[QUOTE="Bill Thomas, post: 142761, member: 485"] I raced my L/ning rep' for 7 years, It was not as fast as it should have been, My road Special was much faster, But I did have 12 to 1 pistons and 36 mm Delloroto carb's, In the road bike !. But by the time I built the L/ning they had started messing with the petrol, You could not get 100 octane leaded petrol at the road pumps anymore, So I had to drop to 9 to 1 pistons, Some of the racers cheated and used aircraft petrol, But I didn't want to go that way. Others don't agree, But I think the BIG piston gives a lot of extra power. If I had my time again, I would use a "D" Distributor, Even though I would have to carry a battery, With dead loss electrics, The battery would still last more than a race meeting. The old type mag' was a Bodge up of an 180 degree mag', You can't have 2 strong sparks, With a 50 degree V Twin. And when you convert it to Manual , I think it's even worse, I had it done by a top Mag' bloke. If you could get a Scintiller Mag' they were different. Good Luck, Bill. [/QUOTE]
