My 2000 Sportsman 500 recently began running terribly. When I start it, it will idle fine, but as soon as I give it any gas, it bogs down and occasionally backfires. The carb has the same sound as when you are trying to start it with the throttle wide open. I opened the air box and looked around. The carb is a Mikuni. I ran some carb cleaner through it, but no help. Anyone got any suggestions on what the problem might be.
Thanks

 

probly time to either bring it in to get a carb kit put into it. it is 9yrs old. think its time.

 

Thanks, Chuck. Is the dealer the best place to get a carb kit?
