Have you ever bought a bike, and once you had to open it up you found things that made you say "Aw CRAP!"?
These are the cam cap journals from my GS1150. The short towers are for holding the valve cover in place.
Here's what I went through. Kind of a PIA but hey, whadda ya want.
You can see the small crack. While not bad, doesn't give one the warm fuzzies. So, I made a fixture to mount in the lathe and get the hole running true.
Machining the register. Just wanted a true diameter. Size wasn't important.
Once that was done I turned a collar that was about a .001" slip fit on the register I had just machined.
Collar installed with some Loctite RC680. That ought to keep it in place.

Oh, it gets worse. On to the second tower.
This one won't be so easy.
Using the same fixture, I bored and threaded what was left of the original hole. Being careful not to machine any deeper than the depth of original hole. Breaking into the cam journal is BAD.
Next, a threaded insert to screw in place. I also threaded the "tower" portion, because I intend to (in belt and suspenders fashion) slather JB Weld over it to (hopefully) make the repair as strong as possible.
Insert Loctited into place. Will finish it up tomorrow, after everything cures.
