I have a 2006 YZ450 for a spare bike that has a lot of hours but still runs very strong. I have put probably 4 or 5 different clutch cover gaskets in it over the years and the odd time they leak a couple rides after being put in. I just see a little seepage on top near the kickstart never very much.
Am I possibly putting it in improperly? I make sure not to over tighten and tighten on one across from the other like the pattern when putting a truck wheel on. It could also be possible the cover is warped but my plates have never shown signs of overheating.
If there's a trick anyone knows that I haven't figured out please let me know!
