Argh! Fork Bottom Bolt head stripped.

I've got a trackday at Tsukuba at the end of the month and thought I should get around to freshening up the forks. All of my experience has been with twin chamber forks (my CRF450 motard), but I knew going into this it shouldn't be any harder.

Well...

I got the one fork all apart and cleaned and ready to put back together, but the second fork was a party pooper. So I stripped the allen head bottom bolt (6mm). I even tapped a 1/4" allen into it but it only stripped it more. Keep in mind I haven't stripped the threads, but the head of the bolt.

Not sure what else to do than start drilling the head off. But what a pain since it's recessed into the fork lower.

Any other thoughts?

Drill the head off. I've done a few of them. What remains of the bolt won't be tight in the damper rod.

I've used a torx bit to remove a stripped out allen key bolt before, knocked it in with a hammer and then removed the bolt using a breaker bar. I used soft jaws in a bench vice to hold the fork. I dont trust my drilling enough to remain straight without going off line. Confused

A possibility before pulling out the drill bits. Me thinks this one got overtightened by gorilla though.

Will let ya know how it goes!

Try heating the bolt first as well just in case it has a bit of corrosion or if they used locktite on it. I have a nice big heavy 80watt soldering pencil for that kinda thing.

Well, I was about to use a nice torx bit but remembered the set cost a pretty penny, so I started drilling it out. Started with 7/32", 1/4", then 8mm for the final head drilling. Sure enough, the bolt head fell out and the threaded part came out by hand!

Rebuilt according to the tuning page specs and I'm liking it already!
