02 yamaha raptor bogging
My 02 yamaha raptor is starts up and idles but bogs,sputters and backfires when you give it gas.It was running okay but took a little time to warm up then it all of a sudden started bogging when you give it gas.It was running strong and fast.I have replaced the spark plug which looked okay and tested the wire and coil.It has a K&N filter but is otherwise stock.Do you think it is the carbs, ignition or valves? Thanks for your time.
