Did you check that you're getting full rpm out of your engine? Belt clutch or centrifugal clutch? What size rear tires?

For one thing your final gear ratio is 7.50-1
If you are running governed 3650 rpm your doing about 23-24 mph with your setup ,that's why you have no straightaway speed

With the governor removed you should have a Billet Flywheel.
