Anybody done the valves on an 04WR450.

Since I don't have valve spring clamps or a surface gauge I guess I'm SoL
If you've done yours what did you see, did they require adjustment. How often do they need to be done. Do you need any special tools. How hard is it
Can anyone list a step by step procedure for those of us that have never done valves on the new generation 4 stroke.

No special tools are required except long skinny feeler guages.
Buy the hot cams shim kit for $60. that has all the necessary shims for changing clearences. Instructions are easy to follow from the manual.
Note watch out for the bearing half ring circlips that locate the camshaft bearings! They like to lift up with the cam and fall off into the engine.

After rereading the manual again I did find the section (3-19 - 3-24) that explains the clearence adjustment process. Where did you get the hot cam kit? HAve you had to make many adjustments to yours. Where I ride there is a mix of stuff. I do like to ride fast and occasionally I end up in the sand. So I would have to say that my engine is reving at race speeds about 70% of the time. Doing big climbs or in the sand, or on long straight-aways.
