MSA Kart Race Yearbook – 2007
Introduction Welcome to the tenth (2007) edition of the MSA Kart Race Yearbook. We hope that all users will find it helpful and informative. Produced with the agreement and support of all kart associations and the kart trade it includes details of all nationally recognised classes. This yearbook is reviewed and revised each year and with an agreed intention towards an inbuilt stability. Copies are distributed to all MSA licensed kart competitors, officials and clubs and also included with ‘Starting in Karting’ Packs. Additional copies may be obtained from the MSA at £8.00 each including postage. We welcome all practical suggestions for the next issue which should be directed to the MSA.
How to use this book Classes are detailed in their prime form as defined by the sponsoring organisation followed by notes to describe additional regulations used by an association or championship, e.g. Cadet (Comer) is a MSA class; ABkC, BSA, ASKC, NKRA or commercial additional regulations are covered in the footnotes. Where junior and senior classes share significant commonality the main class regulations will be found in the junior section and differences for the senior class are identified in the text, e.g. Formula TKM. General competition, technical and safety regulations remain in the MSA Competitors Yearbook (Blue Book) which must be referred to in conjunction with the regulations reproduced herein and which takes precedence. Full details of international regulations are contained in the CIK Yearbook which should also be referred to for applicable classes. For convenience we have included relevant extracts from the draft 2007 CIK Yearbook where known. Competitors intending to enter International events or classes should obtain a copy of the CIK Yearbook and ensure up to date compliance. Regulation changes from the previous year are shaded.
General Notes 1. Silencing. Sound level requirements for British karting are constantly under review. Competitors should ensure that their equipment conforms to the levels defined in MSA regulations or as amended by venue local requirements. Where appropriate additional regulations are given in Appendix 3. 2. Weights. All classes show minimum weights and these are defined as the minimum weight acceptable for the kart plus driver and equipment (race condition) at any time. Class weights may be amended upwards for club or championship events. Where such a change is detailed in these regulations this will be signified by an asterisk (*). 3. Class Categories. The following table details main kart race categories and their appropriate classifications. The classification provides guidance for clubs as to which classes may be amalgamated if required for race grids. It also provides guidance for the performance categories in which any new class should be made compatible. 4. Class Regulations. Queries on the class regulations should be sent in the first instance to the class promoter, as shown in the ‘Affiliation’ section of each class. All clubs must specify the classes they offer in their supplementary or championship regulations with a reference to the MSA Kart Race Yearbook and their particular association’s regulations, and have a reference to the source of the class regulations if found elsewhere e.g.
‘TECHNICAL REGULATIONS. MSA 2007 Specific karting technical regulations apply together with the 2007 (insert your club’s association) regulations within the 2007 MSA Kart Race Yearbook and the SR’s for the meeting.
ELIGIBLE CLASSES: All (insert your club’s association) classes plus ‘xx’ and ‘yy’ are offered, except that Formula ‘zz’ is not offered. The regulations for all classes offered may be found in the 2007 MSA Kart Race Yearbook. Additionally Formula ‘??’ is offered under MSA Regulation N.1.3, the class regulations are available from: (name and address of class promoter).’
This document has been compiled using the best available information. The MSA accepts no responsibility for any errors or omissions.

When a manufacturer already has two homologated chassis, if he homologates a new design, he cannot continue to produce chassis to the old homologation. From 1.1.2007 a new chassis homologation period came into force. Manufacturers may only produce and sell a maximum of two homologated model styles at any one time. All karts must carry appropriate chassis markings. Reference in this document to 2007 homologation karts means any kart listed in the appendix of karts covered by the 2007 homologation period. B3.3.2 Drivers may compete in any homologated chassis that appears in Appendix 1, providing it meets all other requirements. The next homologation period will commence 1.1.2010. All chassis made after 1-1-98 must carry the official Formula TKM sequential plate securely riveted to the brake side bearing hanger together with the manufacturer's stamped chassis number. These sequential plates are unique to each kart, non transferable and must only be applied by the manufacturer at the time of manufacture. Karts under the 1998, 2001, 2004 & 2007 homologation list must not have detachable plates carrying the manufacturer's chassis number and year of manufacture. Chassis number must incorporate the year of manufacture. In the case of lost/damaged sequential plates, a special procedure is used to issue replacements via the manufacturer. B3.3.3 Chassis to be constructed from magnetic steel tubing, cross section free. The method of welding/brazing is free but for all main chassis joins welding/brazing is obligatory - i.e. no clamping, sliding members or torsional adjustments including additional bolt-in torsion bars. The use of any type of hydraulic or similar damping device for any purpose is specifically prohibited. B3.3.4 Engine must be mounted to the right hand side, driver seated facing to the front. B3.3.5 The rear axle must be of parallel magnetic steel, 30mm nominal diameter, with hub retention. The axle can be either solid or hollow with a minimum nominal parallel wall thickness throughout its length of 5mm. It must be supported in two bearings only, using any type of bearing and retention method including cassette type. No other bearings or stiffening devices may be attached to the rear axle for any purpose. It is permitted to use circular collars around the rear axle immediately next to the axle bearings to prevent axle movement. They must not exceed 12mm in

width and must be fitted for the sole purpose of axle location. It is permitted to semi-drill the axle for grub screw location. B3.3.6 Rear axle quick release fittings are permitted. Hubs may overhang the ends of the rear axle providing they are expressly designed to do so. Bearing spacers or adapters are permitted. Adjustable rear ride height not permitted. Use of non original parts to effect changed rear ride height not permitted. Ride height axle height position as homologated. B3.3.8 The steering must have non-adjustable castor and camber angles. Castor and camber angles of the chassis must be as homologated. Steering column may have more than one hole which can be utilised for twin-hole Ackerman type steering operation. Stub axles may contain more than one bolt hole in their drag arm. Any hole may be used. Stub axles must be as supplied and fitted to new karts by the manufacturer homologating the kart. In other respects such as length of axle shaft and its angle, and the drag arm length and attachment holes, the stub is free. The king pin bolts must be centrally positioned in both the frame stub axle mounts and stub axles. The position of the holes must be non adjustable and permanently mounted. Detachable hole inserts not permitted. B3.3.9 Front ride height adjustment is permitted by movement of washers/spacers between the frame stub axle mounts and stub axle. On 1998, 2001, 2004 & 2007 homologated chassis the maximum permitted adjustment by this method is 12mm. No modifications may be carried out to the homologated design to achieve or increase this. B3.3.10 All karts must have the steering column mounted in such a way that even if the bottom retaining bolt is removed it cannot pull free from its lower bearing. B3.3.11 The only additions permitted to homologated chassis are: Equipment to meet latest MSA safety regulations, seat and a Nassau panel, along with the mountings solely concerned with their fitment. The following must not be added: Rear, front or side torsion bars, or any parts not homologated other than the exceptions indicated in these regulations. B3.3.12 The following parts are specifically prohibited: Components made from Kevlar, Carbon Fibre, Titanium or other similar exotic materials, other than for the seat and floor tray which is optional. The use of plastic or similar materials for components such as wheels, wheel hubs/bosses, sprocket and brake disc carriers is expressly forbidden. B3.3.13 Additional bolt on seat stays/mountings are permitted to a maximum of one per side, position and style free. B3.3.14 Use of sidepods and front fairing is mandatory. Type and style free but must conform to MSA Technical Regulations. Chassis may use old traditional diagonal type or CIK parallel type side bodywork mountings but not a choice. It is not permitted to modify the side bodywork mounting points on the chassis. It is permitted for manufacturers to sell pre 2007 homologated chassis modified with CIK parallel type side bodywork mountings, where suitable homologation/amendment paperwork exists. Note that where a kart is fitted with a traditional front bumper incorporating two vertical front uprights it is permitted to make use of the CIK front fairings. In this case, as long as the two vertical uprights remain in place, the requirement for an aluminium or steel securing block as per MSA rule 14.13.2 is waived. The fairing may be attached to the kart by any safe and secure method in two places, not necessarily the CIK type clips. Sidepods may incorporate suitable holes for starter shaft, airbox trumpet, etc where MSA rules permit. Their ends may be sealed to prevent the flow of water. 2007 homologation karts must use CIK homologated crash-tested bodywork with matching attachments. B3.3.15 Front and rear bumpers must comply to MSA Technical Regulations. Neither may incorporate adjustable torsion by design. Bolt in type torsion bars are specifically prohibited. Front bumper must not use rubber, nylon or similar material in its fastenings/mountings. Rear bumper may use rubber, nylon or similar material for a maximum of two of its fastenings/mountings to the frame but may be secured by more than these two fixings and may for example have bracing struts to the axle housing providing these were part of the original homologation. B3.3.16 Drivers may make use of tank tape, cable ties, thin wire or throttle cable type bowden cable in ensuring that items such as exhaust, bumpers, electrical wiring, chain guard, etc. do not come off during the course of racing. One or more fixings may be used, however the item used must only be there for secondary security and reliability purposes and must not be attached in such a manner that it affects torsional adjustment of the kart or provides any other performance advantage.

The only spark plugs permitted are as listed and must be unmodified with sealing washer in place. The list of spark plugs is as follows: DENSO – W27ES-ZU, W31ES-ZU, IW27 and IW 31 NGK – B9EG, B10EG, BR9EG, BR10EG, B9EGV, B10EGV, BR9EIX and BR10EIX. B3.4.17 A minimal amount of machining is permitted to the cylinder head subject to stringent conditions, primarily intended to allow rectification of engines that have suffered head damage. This must be carried out in line with the drawings laid out in the fiche. Note that the squish angle face of 12 degrees plus or minus 1 degree must meet and intersect the liner mating face of the cylinder head at that angle, with no intermediary angles or curves throughout their full circumference. Any form of step, recess, groove or similar will render the cylinder head illegal since it will not follow the original shape. B3.4.18 The cylinder head and/or liner mating face(s) must remain flat. If machining or any other operation is carried out on the cylinder head and/or liner mating face(s), the mating faces must always remain flat over the full extent of their original surface. B3.4.19 It is permitted to use helicoil type thread replacements to repair critical engine fixings on the cylinder head, crankcase and cylinder barrel. Any other type of repair or insert is prohibited. Such repairs must not be used to derive any benefit other than rectification of damage. In the case of the spark plug thread, no portion of the helicoil may protrude outside of the normal thread area. The coil must be inserted to the full length of the original thread and only one continuous coil to be used per repaired thread. In all cases the size of the repaired threads must remain as standard. It is permitted to repair with helicoils threads (M3 or M4) on the carburettor providing they do not perform any other function. B3.4.20 When measuring the inlet and exhaust port timing it is clarified that the maximum contact pressure on the feeler gauge should be only that achieved through finger pressure on either one of the crank nuts. The dial gauge and fixture block used for this purpose must be tightened down at 13lb/ft on each of the two nuts. The nuts/studs must have threads in good condition, lubricated, and with nuts which can be easily moved by finger-only pressure at the point of being tightened. B3.4.21 All gaskets used in or on the engine must be of original TKM supply and must be fitted in accordance with the engine fiche. Only one gasket is permitted on any engine part with the exception of the barrel to crankcase mating face where it is permitted to use up to a total of any three of the standard 3 alternative thickness TKM supplied gaskets. Use of gasket sealer/grease is permitted. B3.4.22 It is permitted to fit additional silencing where required by MSA or local club regulations, provided that the original complete TKM equipment is still used in unmodified form. B3.4.23 The only exhaust end can permitted is that provided by Tal-Ko and marked with the TKM logo. B3.4.24 When taking measurement of the cylinder head volume, the cylinder head must be fitted to the engine in the manufacturer’s normal manner with the standard four brass head nuts (or approved TKM sealing nuts) tightened to 13lb/ft and the two small allen headed bolts tightened to 8lb/ft. The nuts/studs must have threads in good condition, lubricated, and with nuts/threads which can be easily moved by finger-only pressure at the point of being tightened. The engine and other test equipment should be at a cold (ambient) temperature of between –5 C and + 50 C. Any readings taken within this temperature span will be accepted as definitive. The engine must be as raced - e.g. with the same gaskets in position and with no carbon removed from the top of the piston, inside of the combustion chamber, etc. The cylinder head may be removed for inspection by an authorised MSA scrutineer before being replaced for a head volume check.

must be made of the authorised and TKM marked measuring plug. Procedure should follow that laid down by Tal-Ko. An ‘A’ grade burette must be used with oil which meets the specification (available from Tal-Ko). Once it is determined that the oil level has reached the top of the measuring plug hole, the reading should be taken within 30 seconds with no more oil added. B3.4.25 As part of TKM’s commitment to noise reduction, it is mandatory to use effective heatproof webbing or similar material wrapped around the exhaust flex to help reduce noise. B3.4.26 The use of purpose designed TKM fin rubbers is mandatory. All new engines are now fitted with noise reducing fin rubbers as supplied by Tal-Ko. These comprise 10 special rubbers all with TKM logo and either marked H or B to indicate whether for head or barrel. Competitors must use a full set of these rubbers, which may be fitted to older engines. The use of more than 10 rubbers is allowed but not advised. Only TKM rubbers permitted. Where fins have become broken on an engine it is permitted to remove excess sections of the rubbers at this point. B3.4.27 The use of one or more TKM manufactured with TKM logo special steel cylinder head retaining nuts with hole for sealing wire is permitted, even if sealing is not required. Use of such nuts may be mandatory at championship meetings as specified in their regulations. B3.4.28 The use of both piston rings is mandatory. The rings must at all times remain free to operate in the manner in which they were designed and supplied. It is the responsibility of the driver to ensure that the rings are not ‘coked’ in place with carbon or prevented from their normal ‘spring’ effect by other methods. The rings should be appropriate to the piston size used and have a maximum ring gap of 0.5mm when measured with the ring placed squarely 5-10mm down from the top of the cylinder bore. This rule does not apply on Extreme engines with only one piston ring. B3.4.29 Where possible it is recommended that the use of officially sanctioned and part numbered Tal-Ko gauges is used in checking engine measurements. In the case of any discrepancy results using TKM approved gauges will be taken as definitive. B3.4.30 It is permitted to use a TKM manufactured with TKM logo flex ring to help increase the life of the exhaust flex. B3.4.31 Permitted Re-bore (Extreme Specification Engines Only). It is permitted to re-bore the barrel in order to take new TKM Extreme oversize pistons 54.25 – 54.75mm. This modification may be carried out to any age engine. It is also permissible to carry out minor machining to the cylinder head to match as detailed in the latest fiche additions. The pistons in these Extreme engines will have only one piston ring. In all other respects normal Formula TKM rules apply. B3.5 Transmission B3.5.1 The drive must be direct, i.e. the crankshaft and rear axle are connected only by a single length of chain. No belt drive, reduction gears, etc., permitted. Engine sprocket to be 9, 10, or 11 tooth. B3.5.2 Karts may be fitted with the optional Formula TKM Horstman dry clutch.

APPENDIX 3 – Silencing
1. Intake Silencers
1.1 In 100cc classes other than Senior and Junior Formula TKM only CIK-FIA homologated boxes are permitted for ABkC championship events. British made boxes conforming to the CIK specification may be used in club meetings by all classes other than the Formula TKM classes. CIK noise boxes conform to the following nominal specification: a) The intake silencer must make a petrol tight fit with the carburettor interface. b) The minimum volume of the silencer must be 1000cc. c) The material must be non splinterable plastic. d) Have a maximum of two openings for the air intake. e) The air intakes must be unmodified and be a maximum of 23mm diameter for 100cc and Junior Gearbox karts and maximum of 30mm diameter for all other gearbox karts.
1.2 A CIK homologated box must not be modified with the exception of drilling holes in the mounting flange and drilling a maximum of two holes in the box wall, for the sole purpose of mounting on gearbox karts. The carburettor adapter is free providing a petrol tight joint is made between the box and the carburettor. All gearbox karts must have a CIK intake box correctly fitted, or one that is approved by the ABkC for that class.
1.3 In order to obtain ABkC approval 10 boxes must be presented for inspection. The boxes must be professionally produced devices complete with production diagrams. During a noise test, which is made on an overhead microphone, static and on both sides of the kart, the box must give at least equal noise attenuation to a CIK intake box fitted to the same engine. The lap times with the box on test must be comparable with lap times using a CIK box. A sample of the box will be retained by ABkC as a reference. An ABkC approved box must be permanently marked with its ABkC approval code in order to be deemed legal for use.
1.4 The following intake boxes have been approved by the ABkC for use on all gearbox karts with the exception of the Europa, Junior Gearbox, ICC (UK) and Super ICC classes:- Single Cylinder FIS/2RV Motivation Design and Development Filtered Induction Silencer System Assembly, side fitting for rotary valve gearbox class engines, fitted with Pipercross foam filter element. Approval expires 31/12/2007. Twin Cylinder FIS/2T Motivation Design and Development Filtered Induction Silencer System Assembly, side fitting for rotary valve twin cylinder gearbox class engines, fitted with Pipercross foam filter elements. Approval expires 31/12/2007. Single Cylinder FIS/2PR Motivation Design and Development Filtered Induction Silencer System Assembly, for reed valve or piston port induction single cylinder gearbox engines, fitted with Pipercross foam filter element. Approval expires 31/12/2007. It must be fitted with the intake trumpets facing towards the ground. Not applicable to 250E. Note that the intake box designated GB1/94 is no longer approved
1.5 Formula 210. All air entering the carburettor must flow through either a K & N cylindrical filter, Part No. RU 0840, or a K & N conical filter, Part No. RU 9220. These intake filters must only be used with an exhaust muffler conforming to 20.8.5.2. An air box conforming to the CIK specification or an air box approved by the ABkC may also be used.
2. Exhaust Silencers
2.1 Unless specifically authorised exhaust lengths may not be varied whilst the kart is in motion. Any such system must be failsafe in operation, not present a hazard and incorporate a measurable reduction in sound level. It should be noted that authorisation will only be given for applications for Formula 100 National as the majority of classes do not allow such systems.
61 Gold Book Pages 2007.ps - 11/30/2006 7:45 AM
MSA Kart Race Yearbook – 2007
2.2 The following regulations 2.3 and 2.4 are mandatory for all gearbox classes except Europa 125. The following regulation 2.5 is mandatory for all gearbox classes except 125 Europa and 210 National.
2.3 Karts shall be provided with an exhaust silencer lying approximately parallel to the rear axle of the kart, and fed by a gas-tight tubed link pipe of a minimum 300mm length from the exit of the expansion chamber to the entrance of the silencer/muffler. In Formula 250E at least one silencer must lie approximately parallel to the axle.
2.4 The link pipe must have a bend of approximately 180 degrees for engines exhaust ported to the rear. For engines exhaust ported to the front, the bend must be between approximately 45 degrees and approximately 180 degrees. Formula 250E is exempt from these bend angle requirements.
2.5 The muffler must have an external minimum cross-section 100mm and a minimum canister length of 380mm. The canister must be used with muffling material and/or baffling plates to be an efficient silencer. The exhaust exit diameter of the canister must be no greater than 38mm.
2.6 Formula 250E: Mufflers as above, two to be fitted.
2.7 Formula 210. All gasses leaving the engine must pass through a muffler with minimum active length 47.5cm, external minimum cross-section 100mm, with an inner tube of maximum bore 4.0cm which must have perforations over the majority of its complete length. The muffler must be connected to the exhaust tailpipe by a nominal 180 degree bend or flexible pipe.
3. General
3.1 The black flag will be shown during a race to signify that a kart is exceeding the sound level limit for the class or circuit. Drivers must return to the pits and report to the Clerk of the Course. If the silencing system is broken during a race the driver must stop in a safe place as soon as is practical and not attempt to continue or return to the pits.
3.2 Attention must be given to silencing systems maintenance. With the published reductions to permitted levels it is important that flex connections and joints are checked regularly and made good. Exhaust silencers that are capable of being repacked, such as Rotax 125 Max, can suffer from declining performance and it is essential that repacking is carried out in accordance with manufacturers instructions.

APPENDIX 4 – ABkC Additional Regulations to the MSA Kart Race Handbook – 2007
A. General
The Association of British Kart Clubs (ABkC) was formed in 1990 to act as an interface between kart clubs and the sports governing body, the MSA, with whom there is a high degree of discussion and co-operation. The clubs are represented by a Steering Group, which is elected each year during the ABkC AGM, which is held in the Autumn.
The regulations contained in the 2007 Kart Race Yearbook and referred to as ABkC affiliations and/or ABkC rules represent the class structure being used by the Association in its direct drive and gearbox national championships. All clubs affiliated to ABkC have agreed to use these regulations for their race meetings. Without this co-operation it would be impossible for drivers to move from club to club during the racing season and find the same race classes.
This document should be used as an addition to the Club’s Supplementary Regulations and used as the reference point for the classes.
All ABkC clubs must run their meetings according to the regulations set down by the MSA. The officials and all safety regulations must conform to the current MSA Yearbook, the ABkC specific regulations are only the class regulations. The ABkC reserves the right to conform to changes in CIK regulations that occur after the publication of the 2007 Kart Race Yearbook.
Information printed in italics relates to regulations that will come into force in the future should the member Clubs agree. Regulations which contain numerals in brackets e.g. (N.14.8.1) are references taken from the MSA Motor Sports Yearbook. Changes are shaded.
Definitions The ABkC Kart Racing Regulations, were until 1997 published separately and were known as the “Green Book”. These regulations are now incorporated into the 2007 MSA Kart Race Handbook, known as the “Gold Book”, published by the MSA on behalf of them and all the Kart Associations. The MSA British Motor Sports Yearbook, is hereafter called the “Blue Book” The CIK Yearbook of Karting Sport, is hereafter called the “Yellow Book” and is available on the CIK website http://www.cikfia.com/

C.4 The ABkC encourages the use of water cooled 100cc engines and regulations to include these have been introduced (see Formula 100 National 10.4). The ABkC recommends the use of acoustic engine covers or other measures such as inserts between head and cylinder fins to reduce noise to the limits in air cooled classes. This will be especially applicable in the Formula A, ICA and 100 National classes. C.5 It is recommended that clubs incorporate into their supplementary regulations that only one set of slicks be used during a race meeting.
D. Gearbox Class General Regulations
D.1 It is important to note that at club level all 250cc monocylinder karts may race together for either one or more sets of trophies at the club’ s discretion, and similarly all 125cc classes may race together for either one or more sets of trophies. If necessary all gearbox classes may race at the same time. D.2 No more than one set of dry tyres may be used in an ABkC gearbox championship meeting for official practice and racing plus one spare front and one spare rear if the original is damaged as specified in SRs. In the event of a tyre being punctured or damaged during racing an extra replacement tyre may be permitted at the discretion of the Chief Scrutineer and Clerk of Course. D.3 In Formula 210 no form of digital re-programmable ignition is permitted, either by re- programming the ignition system from an external programmer, or by means of add on circuitry. Only a simple add on resistor/capacitor passive circuit is permitted in order to introduce a fixed delay curve to the ignition system. No variation of this curve is permissible whilst the kart is in motion. No active devices such as transistors or integrated circuits are permitted. Devices may be required to be laboratory tested to determine compliance. D.4 Drive by wire and traction control devices are expressly forbidden. D.5 Gear change in Formula 210, Formula 125 Open, Formula 125 ICC (U.K.), Formula Super ICC, and Formula 250 National classes must be mechanical with no electrical, electronic, hydraulic or pneumatic operation or assistance. No form of ignition control to aid gear changing is permitted, for example continuous traction system (cts). D.6 Bodywork Definitions related to karts used on long and short circuits. D.6.1 Long circuit bodywork trim is recognised as including anything in short circuit bodywork trim plus any nose type conforming to kart general regulations, fully enveloping panels, and wings either full width or part width. D.6.2 Short circuit bodywork trim is recognised as including a front fairing plus side-protection bars or side-pods to prevent wheel interlocking as per general kart regulations and optionally either a Nassau panel or bubble. Lateral bodywork and front fairings must never cut the plane through the top of the front and rear tyres. Rear vertical wing ends are permitted but any form of wing or winglets or fully enveloping body panels are not permitted. D.6.3 No part of the kart other than the bolts or clamps fixing the floor tray, the engine, the seat and seat stays, or the brake discs, the front kingpin bolts, the sprocket, the wheels and the tyres, may protrude below the bottom of the main longitudinal chassis rails. The floor tray may be clamped direct to the lower edge of the main longitudinal chassis rails.

MSA Kart Race Yearbook – 2007
D.6.4 The minimum permitted wall thickness of the rear axle is 1.9mm D.7 Kevlar and carbon fibre are not permitted in Formula 125 ICC (U.K.), Super ICC, Formula 210 or Formula 250 National except for seats, silencers, Nassau panels and instrument panels, Carbon fibre or Kevlar bodywork is specifically permitted in Formula 125 Open and Formula 250E. D.8 Homologation and Registration of Engines for ABkC Championships and Club events. D.8.1 ABkC will only allow the registration of new engines into the Formula 125 Open and Formula 250 National classes on a three year basis, the next permitted update of engines in these classes will be for the 2010 season. Engines being put forward for registration should be presented for inspection to the MSA or their designated Association by 1.6.2009. 2007 was the start of a three year period. Engines homologated by the CIK do not need to be separately registered by the MSA unless specified in class regulations. D.8.2 In Formula 125 Open engines must be registered by the CIK for use in Formula C, ICC or Super ICC. Any change to this regulation is not anticipated until the 2008 season. D.9 Re-programmable ignitions Formula 250 National: The ignition system type is open but the electronic unit box and the coil must receive only one feeding energy source of the rotor/stator or of a battery and one crankshaft pick-up signal in order to set the ignition signal. The advance and cartography may under no circumstances be modifiable from the driving seat under normal racing conditions.
E. Lap Scoring & Points Scheme Recommendations
After a survey of the procedures used by member clubs when lap scoring and calculating the grids for the finals during a meeting the following suggestions are made to enable the drivers to understand the system. E.1 System (A) The first placed driver in any heat will be given 0 points, 2nd place 2 points, 3rd place 3 points and so on until the last placed driver, or System (B), the first placed driver will be given the number of points equal to the maximum number on the grid plus two, the second placed driver the maximum less two, the third the maximum less three and so on. E.2 (A) A driver who fails to start a race will take 1 point more than the number of drivers that started the race, or (B) I point less than the maximum number of starters. E.2.1 If the grid is part of a meeting when drivers may not be racing in every grid used for that class, then a non finishing driver will take (A) 1 point more or (B) 1 points less, than the largest starting grid used in that class. E.2.2 Drivers who fail to finish may be given points according to their positions on the lap charts. E.3 A driver who is excluded from a race will take (A) 1 point more, or (B) 1 point less, than the number of drivers that started a race, calculated in exactly the way as in MSA Yearbook Section (E.2.1.) The C of C may decide to increase this penalty under certain circumstances (MSA Yearbook Section O.2). E.4 Lap scoring, when transponders are not being used, should take the form of at least three people independently observing the drivers, this is important should a dispute arise in order that a majority decision may be made. The practice of one person “calling” the drivers is not encouraged! E.5 In order to enable the judicial procedures to proceed with the minimum of complication the lap scoring team are advised to include the following pieces of information on their lap scoring sheets: a) Race start and finish times. b) Number of starters and number of finishers. c) Any other observations pertinent to the result of the race. E.6 In accordance with MSA Yearbook (C 7.1.9) the Chief Lap Scorer will be a judge of fact in respect of laps completed and finishing order. The Chief Lap Scorer must forward the race finishing order to the results team and the Clerk of the Course.
F. Transponder Lap Scoring
F.1 The ABkC and MSA has introduced transponder lap scoring. The nominated system for all ABkC clubs is the AMB TranX 160 system introduced from 1.1.2001. Every driver will be expected to
68 Gold Book Pages 2007.ps - 11/30/2006 7:46 AM
MSA Kart Race Yearbook – 2007
own a transponder by that time, although clubs may hold back up stocks for hire. Clubs not able to comply may apply to the ABkC for a waiver. F.2 The transponder must be fitted in an approximately upright position (ie with the ’R’ clip to the top) on the back of the seat fitted at a height from the ground at 25cm +/- 5cm measured to any point of the transponder. F.2.1 Deleted. F.2.2 Deleted. F.2.3 Transponders must be mounted in accordance with the manufacturer’s recommendations. F.2.4 If transponder lap scoring is in use then at least one lap scorer must manually lap score each race per N 4.9. Transponder decoders must be a certified and approved type. F.2.5 Where timing by transponder is permitted kart timekeepers must be MSA licensed.
G. Tyre Testing Guidelines
G.1 A photo-ionization detector (PID) with a calibration certificate for isobutylene at 100ppm issued in the preceding 12 months may be used for testing for chemical treatment of tyres. G.2 A reading greater than 3ppm on a PID as described in G.1 with the sampling probe within 5mm of any part of the tyre or tread, where the reading is 50% greater than the average readings found on tyres from other competitors in the race will be deemed evidence of chemical treatment as per MSA Yearbook (N 14.6.8.) G.3 If chemical treatment of tyres is established before the race, using the above technique or any other, the competitor will not be allowed to race as chemically treated tyres may constitute a safety risk and contravenes MSA Yearbook (N 14.6.8.). If the event regulations allow then the competitor may at the discretion of the chief scrutineer be given the opportunity to change tyre(s). No additional time will be allowed for this.
