Is that a twin or is it two pipes and two carbs on a single?
It's a 750 twin Mike.
A bike like that one is the reason I have to laugh at many of the riders of today when they complain about their new race bikes. That is a typical (although very nicely done) race bike of the late 70's and 80's. It uses a highly modified 750cc twin Norton engine. Racing cams, extensive porting and flow testing by CR Axtel (local tuner guy). Balanced crank, high compression pistons, special coating treatments and to make them live we had to magnuflux, zyglo and shot pean everything that moved. All fine tuned on a dyno.
The stock frames and wheels were thrown away and replaced with a C&J racing frame, Barnes wheels and disc brake, Cerrani forks and fiberglass or aluminum gas tanks. About the only thing stock on those bikes were the engine cases and they were highly modified. Even the tires were modified. We used to harden the tires and hand cut the tread for different tracks.
Today you can walk into your local dealer and purchase a state-of-the-art racing machine with more power than most riders can even hang on to. You can take it from the dealer directly to the track and be competitive. Yet everyone complains about having to take the time to check their valves and do a little maintainence. :yell: If the riders of today had to go through what we had to back then to build our own bikes, there would be a whole lot less people at the track. :nod:
