Hello. My father bought my son a 2016 outlaw 50 and we are trying to figure out how to make it faster. We have the throttle limiter all the way out. We have not been able to find any aftermarket parts or modifications for this machine. He is 5 and is racing a harescramble series so we can't buy bigger until he is a little older. Someone mentioned removing a spacer behind the clutch to give it a few mph more but i'm not finding any instructions on how to do this. Any advise is appreciated! Thanks!
