rebuild top end (NEW RINGS, MAYBE PISTON, AND HONE OR BORE CYLINDER)
660 will do 60-70 The Warrior was never made in 660 cc. The raptor was the only 660r that Yamaha made.
When you need to, if you seize it or notice low compression, its time for a rebuild, otherwise ride and enjoy it. When I raced, I would usually get a whole season out of an engine, but that was abusing it for a whole year.
Take her apart and rebuild that somebitch!
The top speed of a stock Yamaha Warrior 350 is around 65 to 70 mph. I own a 1998 Warrior 350 and it will go 68 mph. The top speed has not changed more than 5 mph from the time it was introduced until today... I have a 2000 warrior 350 that has been clocked at 117mph and all it has added on is stage 2 carb jets and K&N air filter.
1000
the top end speed is 65mph.
Rebuilding an ATV top end takes some knowledge of engines. Check out my bio page for help.
With the engine at TOP DEAD CENTER (TDC) Adjust the exhuast valve to .007 and the intake to .005.
Boring the engine out will not help the top end speed. This Blaster will go at top end 55 mph at the full throttle.
get a clymer manual for torque specifications.
