I have a 99 Timberwolf that ran great but smoked like crazy. I cleaned the carb and threw a new set of rings it. The smoking stopped, but ever since I got it back together, I have idle issues. at idle, it purrs like a kitten. When I throttle up beyond halfway and hold it, the bike cuts out sounding like I am reving up and down the motor quickly. The timing is fine, but I am lost in figuring out how to get it to fully throttle up and stay that way. Any help would be greatly appreciated.
