09 sportsman 500 bogging down backfiring top end
I recently purchased an 09 sportsman 500 ho. She starts and idles great. When I go a little past half throttle it loses power and almost sounds as though its backfiring.
I've owned numerous 500's in the past and have encountered the dreaded cam problem. This doesn't act quite the same as those did but I still can't rule it out. I figure since it's a different model, perhaps a different issue. I put on a new filter, the intake looks good. I'm out of ideas. I'd appreciate any and all advice!
Not sure if it could possibly be related electrically but my speedometer has stopped working as well.
Any ideas out there?
Thanks so much.
