How do you remove the helmet lock?

Hey all, I'm trying to replace the lock cylinder in the helmet lock on my '86 VF500F, and can't for the life of me figure out how to remove the lock assembly. It looks like it's bolted to the frame, but I have no idea how to unbolt it.
Any help would be great, Thanks.

This is the lock in question:

If it's what I think it is those have anti theft bolts.... There are tools for that .... basicly you need to drill and use a reverse drill bit made to take out striped bolt heads.... Hope someone can come up with a better answer.....

Yeah, I've got a few solutions that involve power tools, I'd just like to do it the "right" way if at all possible.

Now that you have a picture (not to clear).... But that looks like a *torks(*not sure how it's spelled) head screw... if so those can be bought at most hardware stores...... I'd spray it with WD-40 now so it's soaking till you get the right bit...Looks a little rusty.....

TPS modules on later Honda carbs had the same thing. The heads on these things break off when torqued on assembly. One way to go is to slot the heads with a Dremel and then use a flat head screwdriver to remove them. Another is a small, sharp chisel tapped in the counterclockwise direction. And then drilling the head off is the other option.

I did the old Dremel trick. I think I'll pick up a couple torx screws for it.
Thanks all!

Good that you got them off. Silly bolts like that -WTF was honda thinking?

I've had really good luck with the old reverse drill trick. A set of reverse drills is a good investment as sooner or later you are going to need to use them. You can use a regular-twist drill to drill the hole for an easy-out but you are just tightening up the fastener even more. Often I have found that the fastener will just unscrew itself before I am even done drilling it out and I never need to even employ the easy-outs.

The name "easy" out is a bit of a misnomer since they are anything but easy but I've yet to even break one since I've started drilling with the reverse drill trick. Maybe it is because they are looser by the time the drilling is done or maybe it is just because I'm not needing to use them as much and have just been lucky. A broke easyout is a real PITA! -NOW you have a problem!

But the dremel trick works too. I just like to use a method that is part of a slow upscaling of force to get out a stuck (or safety-head) fastener that can't be removed any other way. If the dremel trick fails it's harder to drill out and easier to break the easy-out if it escalates to that point.

I've removed countless numbers of these... I've never came across one that I couldn't get with some fresh Vise-Grips right on the edge.
Good luck, Mike.
