Stripped fork studs
So I just got new tires mounted and balanced, and after I got the axle in place I torqued down the nuts. The manual said to torque them between 26 to 37 ft lbs so I went for the middle and torqued them to 32. The left side went fine, but when I torqued down the right side I stripped the threads on the stud. I was able to get the nuts off by using a wedge to push the nut down while I loosened them. What are my options now? Should I use a die to cut new, smaller threads on the stud or can the studs be removed and replaced?

Re: Stripped fork studs
Replace them. Recutting smaller can compromise strength. You don't want the wheel to come loose.
Think of how stupid the average person is, then realise that half of them are more stupid than that.

Re: Stripped fork studs
Any idea where I can find replacements? I can't seem to locate any. Even the parts diagram of the fork doesn't show it as a separate piece. It's for a 1973 Suzuki GT250.

Remove the old one(s) and measure the length. They are 8mm thread. Any local bolt or fixing supplier will have something similar or even a bolt. Use new washers too.

Re: Stripped fork studs
Suzuki parts diagrams list those studs for some of the other models.
GT250K: https://www.partzilla.com/catalog/suzuk ... ork-gt250k
GS550: https://www.partzilla.com/catalog/suzuk ... front-fork
Those GT250 studs were used on lots of other models. With a bit of sleuthing you should be able to get a useable net set from Suzuki.
Looking at the GT380 shop manual: https://www.oldjapanesebikes.com/mraxl_ ... /index.php
The front axle nut spec is 26 — 38 ft-lb. That is the big nut on the axle.
The front axle stopper nut is 9.5 — 17 lb. Those are the axle holder nuts that you torqued up to 32 ft-lb.
Would be a good to replace all four of those studs & use new washers + nuts.

Re: Stripped fork studs
Thanks for the advice. Replacing it was cheaper and easier than cutting new threads.
