broken front head bolt

[boontonmike]

Has anyone been able to remove the front pinch bolt between 2 and 3 headers on the headafter breaking ? It's the 10mm bolt that pinches the headgasket. I, unluckily, had a weak bolt and when torqueing it decided to snap. This wouldn't have been too bad when the engine was out, but it's all in the frame and I would really hate to have to undo half the build and go backwards that far. Hopefully someone here has some tricks up their sleeve on how to remove the broken bolt while in the frame.

My only idea is to use a flex bit off a drill and do the easy out thing. Ive exhaust my other options up until now of trying to get the bolt to spin using small flatheads and such.

Probably not what you want to hear but I'd pull the head or just tolerate an oil leak.

As Chef says, The head comes off with the motor in the frame and you can do that in a few hours at any point in your build

Fire it up and see if it leaks

An easy out or live with a small leak.

No easy outs
And if you have worked on it to get it this far then reverse and fix it properly
oil leaks on a Japanese motorcycle are an abomination.

That's just bad luck. If it was one of the 10mm bolts on the sides of the head you could probably fix it in place. But that upside-down 10mm one on the front? That's got to be the hardest bolt to try and get to and fix. It doesn't seem like that one little bolt makes much of a difference, but without it you are almost guaranteed an oil leak. If it was me, I would have to remove the head, fix it, and maybe upgrade that bolt to a stainless grade 8 so it wouldn't ever happen again!
