    BSA 1949 A7 500 CC 2 CYL OHV SOLD BSA 1949 A7 The BSA A7 was a British motorcycle manufactured by Birmingham Small Arms Company (BSA) at their factory in Armoury Road, Small Heath, Birmingham in 1946. The 495cc BSA A7 continued in production with minor modifications until 1961.The 495cc twin cylinder engine produced 26bhp and was capable of 85mph. A single camshaft behind the cylinders operated the valves via long pushrods passing through a tunnel in the cast iron block. This system needed a considerable number of studs and nuts to fasten down the cylinder head and V.O.F.

Most motorcycles of this period tensioned the primary chain by drawing or rotating the gearbox backwards on a hinge with threaded rods, this was known as pre-unit construction. The first A7 featured a fixed gearbox, bolted to the back of the crankcase, and an internal tensioner for the duplex primary chain. This gave it the appearance of unit construction and pioneered the system later used in unit-construction engines (eg BSA C12/C15, BSA B40, Triumph 3TA and on). However, in 1954 a re-design reverted to the older system. The electrics (as was universal for larger British motorcycles of the period) consisted of two independent systems, the very reliable and self-contained Lucas magneto, with a dynamo generator to charge the battery and provide lights.

Club Ride Days Above-Right to left; Don, Doug, Peter Trevor and Don’s son Steve out for a Sunday ride mid-January. Trevor’s still trying to bond with his Norton it is running well but he spoke more fondly of his BMWs He has since sold the Norton Peter’s 400 Honda four being checked over Germany vs Russia albeit Adrian’s BMW is far from standard; Neil’s Ural is based on the pre WW2 BMW with many recent factory upgrades President’s rePort – March 2018 We certainly can’t complain about the weather lately perfect for riding and going to rallies. Attendance at the monthly hub runs has been very good and a couple of rides out through the Yarramalong Valley have been great. Quite a few hours have been spent in the Presidential Shed sorting out a number of long overdue projects. A wave of enthusiasm has seen work going on which was long overdue. The 1971 Triumph T25SS Blazer has finally had the leaking timing case attended to and the clutch reassembled. This revealed that the clutch plates probably should be renewed and new friction plates have been ordered.

There’s a theory about how time seems to speed up as you get older. It goes something like this: when you are 10yo, one year is a massive 10% of your life and seems like forever. When you are 100yo, one year is only a meagre 1% of your life and so it seems like nothing as it seems to pass quickly. I think it is Alzheimer’s! No committee meeting this last month due to clashing with the Geelong Show. This also knocked out the Tech/Craft night which is always a bit of fun. As it is November, members are reminded of the many events coming up this month. With the weather being nice, perhaps we will get a few more old cars out on the coffee morning.

They took the A7’s 500cc 62mm bore & 82mm stroke & pushed them out to 70mm X 84mm for a new displacement of 646cc. The bore spacing was wider, so the crank was longer, so the crankcases were bigger & stronger. The one-piece forged steel crank benefited from BSA’s advanced metals division as the rod journals were ‘induction-hardened, ground & polished’.

    Southern Star Magazine of the New Zealand BSA Motorcycle Owners’ Club Inside: Two bikes over the last two winters Women BSA riders 1930s B.S.A. rider Vera Porter rd 23 National BSA Rally Patron: Jeff Smith 2018 Subscriptions Due January - February 2018 1955 BSA A7 500cc Shooting Star. Photograph John Whitcombe. 1954 BSA A10 650cc Golden Flash. Photograph John Whitcombe. Cover: Jacqui Walker up on the Port Hills in Christchurch. 2 Two bikes over the last two winters By John Whitcombe I have been rebuilding two bikes over the last two winters: a 1954 BSA A10 650cc Golden Flash and a 1955 BSA A7 500cc Shooting Star. At the time of writing both bikes are running and almost ready to road test and do the rego and WoFs. The Gold Flash came from Christchurch as a conglomeration of bits consisting of a 1957 BSA Road Rocket completed two years ago and the Gold Flash. This Gold Flash has been my toughest challenge to date and as shown in the photos it was completely disassembled and probably contained parts from more than one bike. This is the reason that I was working on the A7 at the same time, as when the A10 became a bit too much I would put it aside and move to the A7. The A7 was found in Rotorua from a chance conversation that my daughter in law had with a cycling friend. It had been sitting in a farm shed for over 30 years awaiting restoration by its owner. Unfortunately time overtook him and sadly he never made a start on it.
