The shifter shaft leaks sometimes too. Then there is the kickstarter shaft. If you need to replace a leaking decompressor shaft, it requires removing the engine because the XL600 can't have the head cover removed while the engine is still in the frame, unfortunately. If only they had made that a splined shaft with an attaching lever, then we could be leak free very easily. +1 on the ricky stator. Great product, great warranty.
Joel, you forgot one--the clutch arm shaft.
Have to pull the cover to do that one.
