my little brother went to one of my races and wants to try it now im not sure how serious he will b but what kinda upgrades would be cheap yet efficient right now before i even was on this forum gutted the exaust like you all are talking about it has a racing go kart filter (similiar to a k & n) stock shocks but on my 400 i have the stock front shocks how would they work on the rear?
and also should i make it wider or no?
thank you for your time
