Hey guys, I changed my first dirt bike flat on the front tire of my xr650r and to make a long story short, I found that one of the four bolts that hold the clamp over the axle is broken. Are those just studs that I can unscrew and replace, or what? Any suggestions are appreciated, I would really rather not have my front tire come off when it's not supposed to:crazy:! Thanks.

Yes, they are studs that unthread out from the fork. I used some channel lock plyiers to grab ahold of the broken piece and twisted it out. It took some time, but it will come out.

Ok, thanks for the info. I found them at but shipping is like 9 bucks minimum. Do you know a better place to get them?

I found some a good auto part's (speed shop) they had a selection of metric and standerd stud's.They were just like the stocker's maybe a little bettter grade.

You'll want to get them in metric grade 10.9. That is roughly equivalent to SAE Grade 8.

Ok, thanks for all your help guys. I'll try to find them at a parts house, if not I'll get the dealer to order them for me. Thanks again:ride:

Cant you just buy a long thread high grade bolt at a hardware store and cut the end off with a dremel to match the length of the post you pulled off the fork...then back the nut over the cut bolt to ensure clear threads....voila! you'll have the threaded post you need-->just an idea.

If you can't find what you're looking for try McMaster Carr. You will find about all a man needs there...short of women and good bourbon. Ive turned to them many times when I'm on need of an oddity that I can't find locally. I usually get my stuff 3 days after I order with std shipping.

Since I haven't taken mine out yet, do you know if the threads are reversed on one side, in other words do you have to rotate clockwise or counterclockwise to take them out? I found both kinds of studs.

They are normal threads on both ends. I believe the end that threads into the fork is a wee bit longer if I remember right.

Also a neat trick to help remove the old stud is to grid the remaining end into a flat bar. This give loads more bite to vice grips or a good adjustable wrench.

Before you put vise-grips on the broken stud, if there is enough thread, put 2 nuts on the threads and tighten the outer nut against the inner nut. You should be able to put a wrench on the inner nut and back the stud out. These 4 studs seems to get overtorqued a lot (I replaced all 4 when I snapped one off since it was a used bike and I didn't know what the guy before had done).

That's all good advice, thanks a lot! I was able to order them from a local dealer so I'm in good shape. You're probably right about over-tourquing, the manual only calls for like 9 ft-lbs of tourque on them. I just snugged up the three good ones and threadlocked them so I could test my tire here in the yard. I'll change the broken one when they come in and have a spare for just in case.

I would apply some heat (not too much) to the fork tube where the threads are. I'm sure the use some Loc-tite stuff in the threads. The heat will soften up the goo and make it easier to come out.
