Im tearing my motor down to prepare for the top end gasket set and throttle/clutch cables ill be receiving soon. also ive never inspected the internals and i know several other things were rigged up that ive already repaired (bought used). So i have several questions that may turn into a wall of text really fast but ill try to separate into paragraphs.
I wanted to remove the motor from the frame to sand down worn and rusty spots and paint it. It looks like there is a long bolt through the valve cover, the swingarm, and 2 motor mounts at the bottom is this correct? I have 2 of the 3 out but i didnt know if i had to remove the swinger to remove the motor.
It has leaks at the valve cover and the head gasket and a few more im currently tracking down. Hence why im getting the gaskets. The valve cover had 2 stripped bolts when i got it and i stripped 2 more. I have retapped these so the leaks may just be the old oil stains now. Also there are i think 4 round caps, NOT the big hex ones on top for adjusting valves but on the SIDES of the valve cover that take an allen wrench. I dont know what theyre for but one of them leaks around it. Any ideas?
Anyways, i know to check the head to make sure its level before i just install a gasket. If its warped i need it decked. I checked it with a framing square and it appears perfectly flat to me but i wanted to know how tight the tolerances are. Would any warpage be clearly visible to me with a plain straight edge or could it be so small id need a micrometer to check it?
Im also inspecting the cylinder and piston while i sit on the fence about boring it, what exactly do i look for? Piston has black crud on it, cylinder walls look smooth and shiny no scratches, intake valves have black crud and exhaust valves are very light grey. Basically the intake valves look like a rich spark plug and exhaust valves look like a lean one. Is this normal? Im attaching a few pics to help out.
Thanks in advance, im just trying to cross all t’s and dot all i’s, i already dropped a washer from the head stud down the ‘dont drop stuff down this hole’ hole that the timing chain disappears into. Failed to retrieve with magnet. Pics coming
