I have a 92 warrior and it have, 11:25:1 piston and a whiteborther big cam and a big gun and a K&N air filter I am running it with the air box lid and it have stock jett's in it now, it run's good but I think it could be better. Should I try a richer jet, One more thing what sprocket's should I try it have a 14/39 on it now and I am running 20' tire's

 

Yes,it would run much better with a jet kit.

 

ok now what size should I start with. And how do i get it tune right?
