i have a 2002 450 foreman 4x4, i have a carb problem i think, bike will start great when cold but wont idle for long and stalls ALOT when warmed up and hard to start have to hold the throtle open and crank it over and over, any ideas on where to start on this???

 

If The air filter is in good shape and clean it maybe time to tear into The carb. Probably not what you wanted to hear though.
