2018 RULEBOOK PRO STREET Changes from Last Season Are Made in BLUE
2018 RULEBOOK PRO STREET Changes from last season are made in BLUE. Revisions during the season are made in RED. Revised 3/7/18 CLASS DESCRIPTION: This class contests the ultimate in street‐legal motorcycles. Created to legitimize illicit street racing, Pro Street is reserved for stock‐appearing motorcycles with unlimited engine modifications. All bikes must be street legal and be powered by self‐starting motorcycle engines. DESIGNATION: The class designation is PST. All entrants must display this designation on both sides of their motorcycle by their bike number. FORMAT: This is a 1/4 mile heads‐up class run on a .400 pro tree. The class will qualify a 16‐bike field and place them on a pro ladder. There will also be a "B Class” for riders that qualified 17th – 32nd and they will be placed on a separate pro ladder. No alternates will be used in either class if a rider is broken. CHANGING BIKES: A racer can change his or her bike in qualifying if there is still another qualifying session for the class, however all previous qualifying data will be erased and the racer must re‐qualify the new bike (You still need to notify the tower to change). The bike and rider that runs first round is the one that must be used for the remainder of eliminations, even if the class is completed on another weekend due to weather. POINTS: This class will be a points class at all XDA, MAN CUP & NHDRO events. BIG‐BORE BIKES: Production big‐bore bikes are permitted a single power adder. -

ZDDP and Cam Wear: Just Another Engine Oil Myth?
ZPlus, LLC Burlington, NC 27215 www.zddplus.com ZDDPlus™ Tech Brief #2 ZDDP and Cam Wear: Just Another Engine Oil Myth? In the Dec. 2007 GM Techlink publication for GM dealers and technicians, GM engineer and author Bob Olree speculated that the current spate of cam and lifter failures being caused by newer oil is a myth, similar to others which have persisted in automotive mythology. He opens with the statement: “Engine Oil Myths - Over the years there has been an overabundance of engine oil myths. Here are some facts you may want to pass along to customers to help debunk the fiction behind these myths.” This is, of course, absolutely true. In the absence of facts, rumors are generated and persist far beyond any applicability to the situation which gave them life. Olree then continues, giving individual cases to illustrate his point. We examined each of the cases in an effort to decide whether or not his point is valid. Case 1 – Pennsylvania Crude Myth “The Pennsylvania Crude Myth - This myth is based on a misapplication of truth. In 1859, the first commercially successful oil well was drilled in Titusville, Pennsylvania. A myth got started before World War II claiming that the only good oils were those made from pure Pennsylvania crude oil. At the time, only minimal refining was used to make engine oil from crude oil. Under these refining conditions, Pennsylvania crude oil made better engine oil than Texas crude or California crude. Today, with modern refining methods, almost any crude can be made into good engine oil. -
Film Thickness and Shape Evaluation in a Cam-Follower Line Contact with Digital Image Processing

Its evaluation in a cam-follower contact is not easy due to the continuous variations of speed, load and geometry during the camshaft rotation. In this work, experimental apparatus with a system for film thickness and shape estimation using optical interferometry, is described. The basic principles of the interferometric techniques and the color spaces used to describe the color components of the fringes of the interference images are reported. Programs for calibration and image analysis, previously developed for point contacts, have been improved and specifically modified for line contacts. The essential steps of the calibration procedure are illustrated. Some experimental interference images obtained with both Hertzian and elastohydrodynamic lubricated cam-follower line contacts are analyzed. The results show program is capable of being used in very different conditions. The methodology developed seems to be promising for a quasi-automatic analysis of large numbers of interference images recorded during camshaft rotation. -
Building Lightning Quick Dragbikes Is Profession for Chris Jones
Building Lightning Quick Dragbikes is Profession for Chris Jones By Terry Witt Senior Staff Writer Chris Jones builds high performance motorcycles that might as well have wings. His bikes can fly down a quarter-mile drag race at close to 200 miles per hour. In his shop in south Chiefland, Jones has built drag racing motorcycles that captured three national titles, won 40 other national races and set national speed records. He is a professional in the motorcycle dragbike business at the national level. His motorcycles have been featured in national magazine advertisements. “Everyone knows on the national level I can build a fast bike,” Jones said. One of his motorcycles reached a speed of 203 miles per hour in 7.4 seconds in the quarter mile. He won his first national championship in 2009 Chiefland professional motorcycle racer Chris when a ZX14 Turbo ridden by John Fernandez Jones stands next to his latest creation, a ZX14 took the AMA Dragbike National Championship Kawasaki dragracing motorcycle that can in the Super-Street Class. accelerate to 200 miles per hour in a quarter of a Jones won the 2012 Manufacturers Cub mile.

Most people refer to them as gel batteries. Our Twin GRAPHICS Power™ batteries have several things that distinguish them as superior to standard conventional wet batteries and other sealed batteries. • They are completely sealed and maintenance free. This design eliminates the need to add water and prevents corrosion and acid CONTROL spills on expensive paint and chrome • They are ready to go out of the box. Their valve regulated design allows you to sell a battery without filling and charging it. • They are UPS shippable. This design is non-hazardous rated by the D.O.T. and I.A.T.A. for all methods of shipping including air, which means it can ship without the expense of a hazardous materials fees SUSPENSION • They have more cranking amperage than the competition. The lack of free electrolyte reduces resistance and produces 25% more cranking amperage than the competition • They are designed for the environment. V-Twins are tough on batteries. Twin Power™ batteries were made to hold up to extreme DRIVE amounts of heat and vibration • They have a flexible design. The liquid free design allows you to mount the battery in almost any position (inverted is not recommended) • They have an increased shelf life of 2% monthly self-discharge rate meaning your bike can sit for an extended -
