Helicoil vs loctite thread repair
#2
I've only had one experience with Heli coil. A few years ago a roommate who is a mechanic accidentally stripped the threaded hole for the spark plug on a Suzuki 650. I believe the heads were aluminum. He used the Heli coil but it wouldn't solve the problem and I had to get a new head eventually. So, in aluminum it didn't work.

That's a bad one. No loctite for sure and a helicoil is not the best choice. You first might see if Harley has a self tapping drain plug (common in automive). Basically it's oversize and when you screw it in it taps a new thread. On the helicoil, though it would work, they tend to come out when you take the plug or bolt out. I guess you could use some thread lock on the coil, but there would be no guarantee. If Harley doesn't have a self tapping plug, your best bet would be a Keensert (if they make them thst large). It's like a helicoil, but it has two wedges that you force in mechanically that lock it in place permanently after insertion.

IMO the best repair is with a Timesert. Its not a Slinky type thread repair. Its a solid bushing. Use ATF for running the Timsert tap in and it prevents galling.

I have never used one personally but have a friend who swears by them as a much better alternative to a helicoil....
