Hi,

I suggest to check wether the carburator has a restriction in the holder
check if the clapets (between carb and cilincer) has a restriction
check if the exhaust has a restriction.

But overall: a race-exhaust, a tecnician who personalizes the carb to the local wether conditions by adjusting the jet, an eventually needed unrestriced cdi will improve bigtime.
