how fast do u think this quad would go with these aftermarket parts ProCircuit T-4 Silencer, Jet Kit, K&N cone airfilter with prefilter, and a set of ITP XTC Holeshot tires and wats the top speed bone stock?

 

Im guessing the tires are 20s? ok, its slower than stock.

 

around 61-62mph

 

I think they hit about 60 stock dont they?? prolly 65 with the pipe and sh*t, You need to gear it for top end if you want it to go faster the pipe will just make it produce a little more power but you have to turn your sprokets faster to gain topend.
