    Has anyone tried fixing a stripped spark plug hole with it? I'm thinking it would be possible to add some to the threading in the head (if it isn't too far gone), let set, then chace it with a die. The idea is to do it cheap, with the head on the engine. Just wondering if anyone tried it.

    And no, I don't ride a KLR :lol3.

    Worth a go... I tried making a screw head with it once, without success.
    It claims to do threads but I've never tried it so wouldent know how effective it would be, I reckon it would be ok as a temp measure as not too much stress is placed on it, but how long it will hold out for before it begin s to scrape off into your barrel when taking your plugs in and out, I don't know.

    It won't handle the compression of the motor. A Helicoil insert is not hard to install. It is best to remove the head though.

    As JB Weld is duct tape in a tube...it's not a magic cure all. Use a helicoil in your application.

    Time-sert beats helicoil for spark plug and all other thread restoration.

    They make spark plug repair inserts, every auto parts store will have them. Drill it out, run the tap in, thread in the insert, then hit it a few time with the set and a hammer to lock it in place.

    Not really. I used it to fix the zipper on my Aerostich. It's still holding up after 3 years. :D

    Use a thread repair kit for your spark plug though. It's best done with the head off but you can get by if you put some grease around the hole, and on the tool before you start makeing any metal shavings. I did it that way on a VW one time and it worked out. That bug is probably still running. :lol3

    Yeah, I had 2 stripped plugs on a POS KZ400 once. NAPA sold me correct repair insert and friend suggested I pack the tap with grease to catch the shavings. I went slow, removed tap often and mopped shavings out inside of cylinder best I could before fired it up. Worked fine, considering the project. On anything I have now, I'd pull the head, however. Unless it is my lawnmower...

    Note to self: JB Weld has 1000 uses, not 1001 :lol3

    Just an idea I had for a "quick" fix. I've used the helicoil insert before.

    Thanks

    If I were on the road and needed to get home, yeah I would use it. And I would buy the insert kit at NAPA on my way home...

    I tried this once and only once. When I was younger and itching to ride I fixed and old Kawi dirt bike that had the dual plugs in the head. I figured it only used one of them so it wouldn't hurt to glue the stripped one in with JB Weld. Well it worked.........for about a mile or so. Then spit out the glued in plug dinging the tank then smacking my leg. I normaly don't mind a good walk but that one sucked for some reason. I ended up biting the bullet and getting the heli coil kit at the auto parts store and did it right.
