It's a metal box with two nuts tack welded inside it. Nothing more. I've been trying to find the time (and money) for a new footpeg mount system as I've stripped them out more than I think is acceptable. Then again, the KLR wasn't built for 6ft table tops (sorry about that Tumu ;) Z DC A5X A12X

Question for my understanding: Why not just drilling to the next larger M? size, and then cut a new thread in? That's what I do with a stripped thread (assuming there is enough material around to allow for a larger hole).

Jeff, A helicoil. I was reading an Edelbrock catalog last night and for some of their heads they even advertise that the intake manifold and exhaust manifold bolt holes have been helicoiled for improved strength. So a helicoil is a better than new repair. You can either go with a stock thread of go up a size for improved strength. WHen reassembling make sure to use red loctite on the bolts - blue is for parts that go on and off frequently and red is for the stuff that should more or less stay permanently mounted. I wouldn't get top concerned about the 'quality' of your torque wrench. Over the years most my bikes have had one to four helicoils. Using the advertised torque I've had more than one bolt strip out on nearly every bike I've owned (the only exception was an Italian Cagiva).

Speaking of this, take a look at the torque value specified for the steering stem nut in the Supplement KLR Service Manual for the 2002 on page 17-5. 43 in-lb. I think I'd question this one. Has anyone else spotted any glaring mistakes in the Service Manual? Matt

Might have been mentioned earlier...if so, forgive me. I've always believed that in a case like this a helicoil insert would be the best thing. Installing it is relativly easy, restores the bike back to original specs as far as bolt sizes etc and doesn't weaken the surrounding areas by reducing the amount of metal. Correct me if I'm wrong. -- Cheers, Dave Watkins 1998 KLR 650 " The Prodigal Son" Abacus Technologies 1025 Fonda Court S.E. Calgary, Alberta T2A5S1 V: 403.701.5746 F: 403.266.0626 E. dave@...

If that is the lower nut, I think it adjusts pressure on the head bearings and inch-pounds might be correct. Let's be sure. (Sorry, I do not yet have the manual.) -Jim in AZ

That sounds more like the torque value for the top steering race. The stem nut is usually a pretty high torque.

If you're right the manual is pretty misleading. I figured it was just a mistake. But this same nut IS refereed to as the stem head nut elsewhere so I could be wrong. Wouldn't be the first time. I didn't realize anybody torqued the top steering race. Isn't this nut that's tightened with either a spanner wrench or a screwdriver? Matt
