    Can anyone out there tell me how to replace the clinch studs on the bottom of a a pair of CR 500 83 forks.

    I have never replaced them so just pretend that I am the village idiot and give me the long version...

    Also what is the best stud to replace them with ? Titanium???

    Anyone know the size, length , pitch ( Schimme... might chime in here)

    They are a two sided stud. 7mm x1.25 and 6mm x1.0. I am sure they are available somewhere, but I was not able to find them with a cursory search. This was OK with me since I had broken half of them to begin with. My solution was to install a 6mm spiral insert (Helicoil type) into the lower fork leg and replace all the studs with TI bolts.

    I was given this same information, and have been unable to locate them either. A fix that was explained to me was to remove the studs and replace them with 7mm bolts that have had the hex heads removed. They should be Loctite'd into the fork holes and the holes in the cover plate may need to be enlarged to accomodate the 7mm diameter. I have to replace a few of mine but have yet to tackle it, so keep us posted on what you do.

    Stupid question but how do you remove them? Do you have to turn them counter clockwise to remove e.g. left hand thread?

    Just like you guys, I have never been able to find replacement studs anywhere. Luckily I had a few extra lower fork legs to pirate from so I'm still using the original studs. My next step was to do the all 7mm stud trick described above.

    HuskyT - they are normal RH thread. Put two nuts on the 6mm part and tighten them against each other, then back them out by turning the bottom nut.

    I have a pair of 35 mm buggy whips off of a 1980 390 ... are they the same studs as the 40 mm 83 CR500 forks? If so, I have a complete set of replacements that can be salvaged.

    Thanks - T
