R60/5 Drive Shaft Filler Plug Stripped
On the newly acquired R60/5 (1973) when I checked the drive shaft fluid, I removed the top bolt (not an allen hole) and saw a piece of metal attached to the threads on the plug/bolt. When I tried to tighten, it started spinning.
If it were the bottom I'd be more concerned - wondering if I could either find a longer bolt or use a little red or blue loctite to hold it in place between maintenance cycles.
Otherwise, I could remove FD, take it to a machine shop and get it re-tapped for next size up or heli coiled.
Open to suggestions.
Teflon tape temporary fix
If you want to take the bike around the block or a little further you could always wrap a couple turns of Teflon tap around the plug and reinstall it for a temporary fix. After all its on the top and you may find other little things going on with the bike during your test rides that could be fixed while the threads are being straightened out.
If you have the mechanical ability and tools to remove the final drive and swing arm to take it to a machine shop you should be able to fix it yourself by simply removing the final drive and either helicoil or time cert it or go to a bigger plug all together. Just pull the final drive and be real careful not to bottom out your tap or insert on the drive shaft bell.
