mine is not exactly stock. [img]i/expressions/face-icon-small-smile.gif[/img] but I hit the rev limiter at 93mph. Going to try again after I slap on a CDI with a higher limit. Be nice if I could just throw on a bigger rear sprocket, be way over a 100 easy.

9200 rpm (approximately the OEM cdi's rev limit) will get you 93mph with stock 13/40 gearing and 20" tires according to a gearing calculator.

A larger rear sprocket (more teeth) will reduce your top speed, not increase it. You could use a smaller rear (I know a 39 tooth will work without rubbing the chain on the OEM hub, not sure about a 38 but some have run them) or a larger front sprocket.
