Well after being fed up with valve issues on my 04 and 05 CRf 450's I just bought a 06 YZF450 with about 15 hours on it. The bike is really clean and has been rejetted with a full Dr. D exhaust. It starts on the first kick and I don't even have to crack the throttle like I did on the CRF.

My left fork seal is flowing like a river. I have heard some people complain about the fork seals on the YZF's. Any suggestions, aftermarket seals etc.

Any suggestions on seals or anything else on the YZF would be appreciated. I'm the oddball ball of the group now since all of my buddies still ride CRF's.

I've had good luck so far with the seals from MSRhp (through Thumper Talk). The OEM seals are a little um, lame.

I only just did my first fork seal on my 06 450, left side, mud riding included 150 hours of use so far, must be just a luck thing
