C90 final drive plug thread repair?
Howdy folks! I know, it's my first post, and I know, it's asking for help. I've been lurking for a little bit and just trying to learn, but now I've learned that some ahole jacked up the drain plug on the final drive. I went to change the final drive oil and the plug felt "welded" in place, after some gentle coaxing I found out why, there was no plug gasket on it, and whoever put it in last time added some loc-tite to it. I also found out WHY they added loc-tite to it when I looked at the drain plug and saw metal embedded in the threads. Seems that the final drive drain hole's threads are mostly stripped out and now I'm left holding the bag.
Is there an easy fix for this? I figured a helicoil would do the trick, but the M14x1.25 set I got has a thread chaser that leads the tap down into the drain hole, but it seems like it would go to deep. Should I remove the final drive from the bike, or is there an easy way to get the part with the drain hole off so I can re-thread and install the heli-coil? I was looking around and there are not a lot of C90 final drive hits on google to help me out in how to get the darn thing off so I can do that...
I'm stuck, and I'm sad.
