Runnin on 3 cylinders??

[sknarfs]

When I start my 06 RTX and it's cold it sounds great. But after warm up sounds like it's missing a bit, has been happening this whole season. Still runs really good and my buddies SkiDoo 800 can't pass me but it just doesn't sound right. I have replaced the plugs and still no difference. Any suggestions would be greatly appreciated.

Are you sure it's not a start of an exaust leak?

I'm not sure but the noise hasn't changed all season which is about 1000 miles about 2000 total on the sled

Any chance there is a little water in your fuel?

Sounds like an exhaust leak. When you first start it, stick your head under the skid and look for water vapor escaping from the exhaust system.
