What did you expect to get? what gearing are you using? what size wheels do you have on it? If you have a stock 44t and a 26" wheel the engine is turning 10,500 rpm at 45 mph !

Do you notice the pipe effect? if not the a/f mix might need to be adjusted by jetting differently to get the most from it!Or the engine is not making the power to over come the gearing!

any good engine builder will tell you that when you increase the compression you need to retard the ignition.
The Lightning is more retarded than standard but not as much as the Jaguar CDI.
These engines need a 7.5cc head. Anything less gives too much compression which will cause the cylinder plating to flake off and the bearings to have a short life.

Thanks Doc, wasn't sure.
