a buddy of mine has an old dirt bike with the spark plug threads stripped out. we were thinking about using a helicoil but i thought i would ask on here first. has anybody used them before and if you have do they work ok the bike is an 1982 honda XL250 i would post it in the honda area but yall have been so helpful to me.

thanks kyle

 

Helicoils work well for plug thread repair. You can get a kit at autoparts stores.

 

yah man as long as you drill the hole on center everything will be just fine....they hold their own too

 

Someone put a heli coil on one of my old two stroke bikes once. The thing kept backing out. Someone makes a thread insert for a plug. I have seen them in pictures and they look real good. They are pinned in place so they can't back out. I have no idea where you can find these things, but I would try to find them if you could. If you can't, then the H-coil would work.
