vw151 Posted April 16, 2013 Report Share Posted April 16, 2013 Well, the threads in the head of my KLR are gone after my friend was riding my KLR yesterday. I'll have to figure out how to get new threads. Quote Link to comment Share on other sites More sharing options...
r1crusher Posted April 16, 2013 Report Share Posted April 16, 2013 Looks like you might have enough material there to put in a helicoil. That is really your only option other than another head. Quote Link to comment Share on other sites More sharing options...
jeb Posted April 16, 2013 Report Share Posted April 16, 2013 Helicoil like R1 said if you can get them in the right thread or could use next size larger diameter bolt. Quote Link to comment Share on other sites More sharing options...
vw151 Posted April 16, 2013 Author Report Share Posted April 16, 2013 Yep, helicoil or re tap a bigger diameter. Not sure what kind of bolts are available in the next larger thread. Definitely don't want to replace the head if I don't have to. Quote Link to comment Share on other sites More sharing options...
r1crusher Posted April 16, 2013 Report Share Posted April 16, 2013 Helicoils will be stronger and much less likely to pull out again. Start with the same size first as this will leave you material if you need to go larger. You can remove material but you can't put it back.

I may consult an expert for help putting it in. Quote Link to comment Share on other sites More sharing options...
bshultz0930 Posted April 18, 2013 Report Share Posted April 18, 2013 If I was closer I would help you. They are super simple if you have the correct tools and room to work with. Just read the instructions on the pack you buy. Seriously though, don't let it scare you, it's simple. Drill, tap, install new threads, install bolt.

We are gonna pull the head off so we can do it with a drill press. Quote Link to comment Share on other sites More sharing options...
vw151 Posted April 18, 2013 Author Report Share Posted April 18, 2013 How did your friend manage to strip the threads out while ridding it?I have no idea. the KLR650.net guys say this is a known issue that occures often. Most people just helicoil all 4 when this happens. Quote Link to comment Share on other sites More sharing options...
r1crusher Posted April 18, 2013 Report Share Posted April 18, 2013 A friend is gonna help me next week. We are gonna pull the head off so we can do it with a drill press.Good deal. Still seems like a lot of work extra work to put them in though. A cordless drill with a right angle head and you should be golden. But whatever you think is best. Be sure to tape something thick and soft to the deck of the head so you don't nick or gouge it or just be really careful with it. Don't want to put it back on only to find a leaking head later.Also, if you're not already thinking about it...go ahead and coil the remaining cam cover bolt holes while you're at it. No sense in going back in later for another one getting stripped out. Quote Link to comment Share on other sites More sharing options...

The guys on KLR650.net all said the same thing, I guess these heads are notorious for this. Quote Link to comment Share on other sites More sharing options...
vw151 Posted April 25, 2013 Author Report Share Posted April 25, 2013 My friend Rick helped me fix the KLR yesterday. So.... more pictures.BTW, ended up just doing 1 helicoil and drilling by hand since the threads on the other three holes looked good. Way easier than pulling the head. Original Threads in a different hole, for comparisonHelicoil threads. Quote Link to comment Share on other sites More sharing options...
