So I've got a little 125 ATM which seems to pull nice a strong through all the gears, however it seems to hit top speed far too quickly. It goes strong right up to 60 then can't go any further, due to the limiter, when I know its got more in it. So was just wondering how easy it is to change the final drive in my gearbox? Almost just a cruiser gear. If so any info on where i could get one from would be great... cheers
