Commando drain plug

When I was changing the oil in my bike I noticed that the drain plug didn't want to go back in as easily as it should. Had to fuss with it and it seems loose in the threads. I expect the threads are worn out in the crankcase. What would be the best way to repair it? A Helicoil or a threaded insert?
Next question is how do I insure that the drill will stay exactly aligned when doing the repair?
Orlin had suggested that I use the larger plug to hold a fixture that would keep the drill in the correct location so it doesn't wander. If I don't have to pull the engine to do this I would be happy. If I do then using the table on my drill press would work. Ideas?

You are most welcome, John in Texas ... if you look in for 'sale section' a couple of pages back .... there was a partial set of timeserts advertised ... I had made an offer but no deal ... you may want to take a look .... I think there were 3 or 4 left in kit and the bit and thread cutter were there just used the one time ... maybe ... anyway good luck ...

Got my Timesert kit the other day. Did a test run on a spare set of cases I had. That worked out well but I did use smaller drills and slowly increased the hole size until I used the one supplied with the kit.
Put my bike on the lift and went after it again working my way up with the drills. The biggest problem I had was the I couldn't see as well as I would have wanted to, this isn't a job to be done by Brail. My wearing bi-focal glasses doesn't help. Greased the drills and taps to catch the swarf and had put some oil in the bike to wash out what little if any might be in the crankcase. Going to pick up more oil and filters today and run the engine and change the oil and filters at least twice just in case. Oil and filters are cheap insurance.

Yes, I found the same difficulty with doing this and did largely the same thing you did to flush any swarf. I also bent a couple of q-tips and soaked their ends in oil and used them as brooms to sweep out the hole before flushing.

Good for you John in Texas .... glad to hear you got it done ...
