Fusion 600 with 9200 miles. Pulls fine up to about 7500 RPM's but that's all it has. Tops out a little over 70 MPH on the speedo - normally has no issues up to 80, and probably more. I switched to my spare belt (used) and it was slightly better. I was riding in Canada without much access to parts. I won't ride the sled again this year but wanted to have some ideas on what to look into. I know the plugs are a few seasons old and the powervalves could probably use a cleaning. Belt deflection looked ok. I do have a new belt to try also, but I forgot to bring it with. Anything else to look at? I am hoping to upgrade in the Fall but want to make sure it's running right first.

Check compression on that engine with that many miles on it.
Engine has about 6000 since rebuilt but yeah probably good to check. Put about 950 on it the past few days

I agree with Indy, very hard to see but the smallest crack will cause exactly that, had that happen a few times on my Poos.
Thanks for the input. I'm not sure when I'll get a chance to look at it, but hopefully not too long from now. The sled is stored in a garage a few hours from my house, so I try to be prepared to fix it when I get a chance. Looks like the bellows are about $26 each. Do you think it's likely enough those are bad that I should order them ahead of time or is that just one of many things to look at? I have the gaskets for the valves - I just didn't get around to cleaning them before this year.

I think it is likely enough they're bad, even if they arent, over time they get really thin and are prone to wearing a hole through them so you're already pushing it even if they are still good. My 07 iq 600 carb I sold to my buddy wore a hole through both of them by 5500 miles when he had it.
