gear up kit

How will a secondary gear up kit affect the speed of my ped?

 

what ped? 50 or 125?? they will give like 10/15mph more to your bikes top speed.... as long as its got a bore kit on like 70cc or 172cc.... but will slow down exceleration.... unless you use lighter rollers.... bigger carb and porting... even then exceleration will probs be slower...

 

i run gear-up on a 50cc, now i pull an actual 65 mph, however i have CF reeds and a few other bits.
