Looks like my rings might be gone. After crossing a road I hit the throttle & felt that my sled just didn't pull hard. When I stopped, the engine felt like it was running on 1 cyl. Changed the plugs, same thing & back fires at lower rpm. plugged the spark plug holes with my fingers & looks like the clutch side cyl has allmost no compression. I have no warranty, it was up in Dec. I have been bugging my dealer about rings for the last 2 years & all they say is don't worry about it, if there is a problem it should have gone by know. It is a 04 800HO with 5900kms. Has anyone had any problems getting this covered after there warranty is up.
