What and how much money would it take to get my 400ex to go 70 MPH.If anyone knows or has an estimate please answer thanx.

 

$25, change the gearing

 

i doubt u even have to spend that much. u can get a crappy front (countershaft) sprocket for like 10 bucks. i wouldn't mess with the gearing tho. u'd be better off savin ur money until u can get a good full system exhaust.

 

I bet that your quad will go pretty fast now hey. I put bosin reads in my warrior.

 

Put some bosin reads on it and a K"N air filter on it

 

hey Hubis where did you put the reeds? in your pocket? it's a 4 stroke they don't have reeds.
