I have a 01 Raptor thats kind of acting funny, it'll start up and run and when I take off it'll sputter and I'll give it more gas and it'll smooth out and take off. But it does this only at slow speeds, I've cleaned the carbs and my K&N filter and put a new plug in it. Does anyone have any ideas. Plus what does everyone suggest for the best aftermarket one-one clutch. Ok to the Bansee, it's just like the Raptor it'll start and idle but wont do anything else it just boggs down. I cleaned the carbs on that to and changed the plugs.
