psyctrance Posted January 12, 2006 Share Posted January 12, 2006 Hi All, After numerous valve adjustments, mostly by someone else, the valve cover bolts will likely cheese out during the next adjustment. Has anyone had experience in installing heli colis to resolve the issue? Bike: '97 1100RT - 90K miles and still running great. Thanks, David Link to comment
Rob L Posted January 12, 2006 Share Posted January 12, 2006 I did it on my 98RT. They worked well. I replaced about 7 of the 8 threads! THEN I bought a torque wrench that does 70 inch/pounds Link to comment
psyctrance Posted January 12, 2006 Author Share Posted January 12, 2006 Cool, where did you get the kit? Link to comment
bmweerman Posted January 12, 2006 Share Posted January 12, 2006 I stripped out a couple of mine and tried heli-coils but had MUCH better luck with these More expensive but also more permanent and even I couldn't screw up the install. Good luck Cameron Link to comment

Has anyone had experience in installing heli colis to resolve the issue? Bike: '97 1100RT - 90K miles and still running great. Thanks, David Did one for a fella at a Tech Daze last spring. Easy to do. pack the drill bit flutes with heavy grease - and then drill at a very low RPM - so that it captures all the chips when drilling. Likewise with the tap, pack w/grease before cutting threads. Also, if you're doing one of the two upper bolts on each head, cover the valvetrain with a clean rag/towel. This way you won't have loose chips all over the valvetrain when you're done. Link to comment
psyctrance Posted January 12, 2006 Author Share Posted January 12, 2006 Thanks!, what size should I get? I don't have the manual in front of me, and don't remember the bolt size, I think it's M6. Link to comment
Haynes Posted January 12, 2006 Share Posted January 12, 2006 The bolts are a standard 6mm diameter with 1mm pitch. Link to comment
smiller Posted January 12, 2006 Share Posted January 12, 2006 Heli coils work well and are not difficult to install. Work slowly and follow Mitch's tips and you should be fine. When done the repair will be stronger than new. I learned all this one day when I accidentally set my torque wrench to 18 nm instead of 8... Link to comment
eaglemike Posted January 13, 2006 Share Posted January 13, 2006 I have both the helicoil kit, and the timesert kit. Please let me know, and I can loan one to you. I do have a couple of tech days on KLR's coming up next weekend, and the following weekend, so I need to keep at least one of them. The KLR also uses 6mm bolts on the cam cover, and are notorious for stripping. Each kit has easier or harder characteristics. I've installed thousands of helicoils, and hundred plus time sets. I'll p.m. you my phone number. all the best, Mike Link to comment
KDeline Posted January 13, 2006 Share Posted January 13, 2006 I did not even bother to drill out the hole, the coils are self tapping and went in with no trouble at all. You do have to be careful of the metal shavings though. IMHO the old threads act as a guide so you get the coil in straight. Link to comment

Just my opinion. --Jerry Link to comment

That's is certainly the first time I've ever heard that one. I've been using helicoils for about 28 years. I certainly would have been glad to know that worked before now It's not a method I would recommend. I''m a machine shop owner, and former aerospace quality control manager. There's always the follow the directions thing...........if you care about how long it lasts all the best, Mike Link to comment
Jim VonBaden Posted January 13, 2006 Share Posted January 13, 2006 Drilled and tapped all 8 of my 94 R1100RS. Installed Heli-coils, and never had a problem. Jim Link to comment

Got the tap set from ACE. Link to comment

eaglemike Posted January 13, 2006 Share Posted January 13, 2006 No problem, I just recognized your gray matter did, when you said the inserts were self tapping. MC Link to comment
psyctrance Posted January 13, 2006 Author Share Posted January 13, 2006 Hi eaglemike, Thanks for the offer, but I can get them locally. Really appreciate everyone's help, and will let you know how it turns out. Cheers, David Link to comment
