as per the other thread. That bike is mine. It is in rolling thunder and ray's book. Someone quick quick rode it in the 70s. Anyone know who.....? (the number is a bit of a help ~ no not Barry Sheene!))
At one particular race they weighed it three times as they couldnt believe how light it was.
The rider in question told me that he was leading a rather famous Suzuki rider until..... the new fangled ignition packed up!
Hence on those early bikes the factory riders often switched back to the old ignition set up to give themselves a better chance of finishing the race!
