Anybody know whats wrong with my Rincon ATV?

Question

I have a 2005 650 Rincon. I'm having problem with the power as i'm riding on trails. When i give it gas it goes but without all the power. I've changed the spark plug, checked the spark arrestor and i've drained the fuel in the carburator, but that didn't help. Can anybody help me out?

Answer 1

I hope it's not one of the auto-torque transmissions. They suck.
They always get stuck in the high range and won't go back to low range untill you come to a complete stop every time.
