Hi,
I am Alex, new to the forum. Bought in Autumn the K75RT 1990, I wish I can upload pictures but I cannot figure it out how.
I worked on the thing all winter, stripped down and reassembled, changed and upgraded parts, some maintenance here and there.
Brought it to my mech for a tune up on the engine (sparks, injectors, engine gaskets, etc..) and we found out that one of the bolts of the right cover of the engine, had a stripped bolt. In fact it was slightly leaking. The previous owner was hoping to fix it, but at the end he removed most of the steel casing that is around the bolt, so now you cannot repair it. 
My mech told me he can try to set some high temp epoxy to recreate the casing...let's cross fingers!
Any comment on this would be welcome.

Which bolt? Is the bolt stripped or the threads that hold it?

It is one of the bolts used to attach the right engine cover. The guy probably stripped the bolt and then tried to re-thread the hole, but he completely busted out all the material. I wish I could have images, but basically the bolts are fastened into steel casings, that are embedded in the aluminum part of the engine.

If somebody doesn't know what they're doing then the engine cover shoulder bolts are easy to strip. Torque spec for them is 8 N-m.

If it's one of the threads in a cam bridge. I took one of those to a local engineering shop and had it helicoiled. perfect fix.

I have also had the bottom front one (in the cam chain cover) stripped. I packed that with chemical/epoxy metal and re tapped the thread successfully.

Hi Alex,
