It will do the same speed as before if you use the same sproket sizes, but it will be able to run higher geared sprokets because of the extra power so if you put bigger sprokets on, i think if you are riding on a flat or down hill road it would probs be a max of about 60 if you geared it right, but it would accelerate slow and hills wont be much good nor will off road. But i have to say 60 is ambitious for a pit.

Not true. Make it as fast as you want to within reason. Mine at least hits 60mph (at the time of testing) and i only have 37T rear 16T front sprockets, standard carb and jet and BBR exhaust. Now my bike proberly goes faster cause since then i now have 26mm mikuni carb 110 jet, ooracing no limiter and bigger wheels 14" front 12" rear compared to my old 10"-10" . When i fit my new speedo and sort my sputtering il let you know my true speed.

Keeping it to the point, like dan-mel said you can add a bigger front sprocket to make it have the same grunt of a standard setup 125 pitbike yet gain more top end speed. And a standard 125 pitbike will hit on average 47-50mph and I dont think 60mph is too ambitious as its only 10mph, i would say anything beyond 60mph is ambitious. But anyways you got yourself a nice powerful engine there so you can do what and how you please with it, I would keep standard gearing on it if it was 125 or go no more than 16T front sprocket, but you got more power so would say dont go more than 18T im guessing.
