Front Fork clamp bolt sheared !!!

can anyone help i changed my front  tyre on my ttr 250 and i have over tightened one of the axle  holder bolts [10mm] which caused it to shear [im gutted] and i think they are welded to the fork as anyone got any suggestions on my options without great expense.

Don't panic Wil - they are only studs and I have sheared a few myself over the years disbelief

If there isn't enough of the sheared bolt protruding to get the Mole grips on then drilling and extracting with the proper tool such as an "easy out" will be needed.

The broken section should screw out if you can get a grip of it. Normal RH thread.

I think I have a few spares that aren't exactly the same as the originals. Will have a look in the morning and get back to you.

I can't find my spare studs so guess I used them all - sorry!

I took a stud out of another fork to show you what it looks like whole. The short threaded section goes into the fork. They usually come out quite easily. See the pic below.

It is odd that Yamaha don't show the stud separately on the fork fiche. It would be daft to have to buy a new fork leg just to get over having a broken stud no

They are 35mm long and take an M6 nut. Nearest I could find on eBay is here

Hope that helps?

I had used all my studs but I had a go at tidying up my workbench today (what a state! disbelief ) and found a new packet of them. They are a close enough match (see below) and you are welcome to one if you aren't fixed up now?
