Trying to remove the right side passenger peg/mount from the frame. They're freakin' rounded bolts on the outside so its impossible to get a hold with vice grips. GAHHHH

Hammer and chisel?

That or a dremel and cut a slot in it, try a fairly good slot edge screw driver and the vise grips on the driver. Might give you a bit more control that way.

One time I actually broke the head off a screw on my truck. My dad welded a bolt to the remaining piece of screw and we removed it that way. In other words, we replaced the head of the screw. Very happy

There are special sockets available for bolts or nuts with rounded heads, they work well. You can get them off a tool truck or I think that Sears has some. Peace YAM

I, too, rounded off the bolt trying to remove the right-side passenger peg perch. Frustrated, I stood back and looked at the situation and realized that, if the bike fell on that side, it looked as if the perch would protect the rear brake master cylinder as the perch sticks out further. I elected to leave it alone.

We've used SheWolf's method, too. However you decide to go back at it, apply heat first.

It looks like that is a Torx head bolt so my idea of the special socket will not work. The idea of welding a bolt to the head of the stripped screw works well, it also adds heat to help things out especially if there is loctite on the threads. Another thing that works sometimes is an air chisel, it will bite into the edge of the bolt and turn the head, for that matter a regular chisel will work.
I have been a mechanic for many years and dealt with many broken and stripped bolt heads. Good luck.

Sorry to hear that, almost stripped a sprocket bolt myself.
Sears have the perfect kit to remove stripped heads for $10.00

Good luck.

Please post a link.

I'm thinking some curved vice grips may do the trick...

I cheated.

I knew I wanted them off when I bought the bike. And I'd read stories...

So I casually asked the shop how much to pop them up while doing the prep for me. They said "Ah, no charge..."

When I got the bike, they handed me the mounts and pegs and told me to go see the parts guy who would give me a couple of replacement bolts...

... seems they don't come off very easily for genuine Yamaha mechanics either...

i had to put a little heat on mine to get them off. You can also drill a hole & use an 'easy out' to remove the bolt. Drilling the hole gets it hot & usually loosens it up, too.

Ugh, I just fought those bolts like hell too....

The other side came right off, no problem.

I ended up with 2 stripped nuts, with a broken-off Screw extractor in each one!

My solution was to use an angle-grinder to create a flat top and bottom on the nut and grab it with a vice grips. This worked. As it turns out, the threads were coated heavily in thread lock (orange?).

applying LOTS of heat might losen the thread lock enough to make it actually come out with the standard hex wrench.

Although I like a slot as much as the next guy I would just take a drill with the appropriate size bit and pop the head of the bolt off, after the peg mount is removed the bolt will come out easily
No mess and no potential of slipping with a tool and hacking stuff

i fought these stupid bolts for i dont know how long, too long!

striped them, ruined a couple allen keys, snapped an 'ez out'.
never felt more dumb in my garage than when trying to get these out, and I have done a lot of dumb shit in there.

Im pretty sure they are thread locked on from the factory or when they are assembled, cause after 40 seconds with the propane torch on them, they came out super easy.

good luck

This method sounds good. I don't have and angle grinder so I'll go up to Sears and buy a cheap one. I do have a heat gun so I'll hit with that before the vice grips...

A little heat works wonders with loctite, sounds like you'r on the right track. If the heat gun does not work a small butane torch or a propane torch should do the trick.
