Mine has recently started weeping from the primary shaft cover. I bought the bike second hand and it looks like this has happened before and 'repaired' with silicone. The only problem is, the previous owner/who ever did the job was a bit rough when putting the bottom screw back in and stripped the threads. I cannot get any purchase to tighten it at all so its gone from a slight weep of oil to full blown leak. I have also noticed the the hole has been elongated slightly too.
Any suggestions on a repair? Will a thread insert work or is the hole too small? Anyone used Loctite Form-A-Thread?
I will upload a picture later on.
