our new kymco 400 is just run in and we got it back from the service center yesterday.. on the drive home i was quite dissapointed at how little extra power there was after the throttle stop screw was wound right out.

on the flat i could only just about get to 90kph with quite a bit of run up. is there any way we can get more performance from our quad??

it's a 2009 kymco maxxer 400 4x4 with the auto box and switchable 2wd/4wd.

currently our old barrossa 250 quaterback feels faster up to about 80kph???!!
