voltage regulator or stator

[dmcglone]

i have a 89 worrior 350 it will run for about 10 to 20 mins and then quit it also eats coils bad and at times it has alot of power and other times it doesn't i was wondering if it was the stator or voltage regulator making it eat coils real fast when it quits it it acts like u turned it off and it back fires sometimes

How do know its "eating coils"? The problem you describe sounds like a fuel/carb issue. I don't know what eating coils mean. If your talking pickup coil; how do you know its bad? Did you ohm it out with a multimeter?

No a ignition coil and when u put a good one on it the bike runs good for alittle bit intill it eats it to

Id start with my voltage tester on my battery. Between 14-15 volts is what your looking for here. If that's OK I'd switch to ohms & Ohm out the stator by way of source coil; & then pickup coil. See If both are in spec for your specific machines year.
