Recently I've decided to replace gaskets and seals in the cylinder head cover, but I've ran into some problems. First, the rocker arm seems to be pushed to a highpoint and when trying to seat the cylinder head cover back on, the rocker arm hits the valve and will not let it seat properly, so my question is; is that something that will be pushed down as I tighten the bolts or do I need to adjust the tappets to their loosest setting in order to seat that well? Any help is greatly appreciated. (I have loosened a few of the tappets, which seems to let it seat a little better, still not ideal though, I've also played with the timing and turning the engine over to get the lowest possible seating.)
Secondly, after pulling the bolts I've realized that most of them vary in length and am curious if that is normal or my bike's previous owner took some short cuts.
Thank you to everyone who has advice!
