Not that this will you, but I know exactly how it feels to do something like this. You hit a problem and only make things worse by breaking or loosing something..!!

Try JB Weld, the stuff is pretty good. Don't know if it'll hold, but you don't have too many options that don't involve either time or money.

If you like being stuck on the side of the road, try the quick fix, otherwise do it right.

If it can be transported, take it to a shop. Get them to extract it with a heat wrench.
I't kind of a cross between a bolt extractor, and a torch, and the works good.

Then u can just buy a new bolt and all will be good. Cause well, i don't think the jb will do the job.

I hope that i am understand your problem, and not just spewing advice or of my ass.

good luck

I finally figured out what was wrong with cylinder #4, the carb boot had a crack and it is sucking air. So now I am happy since I know what the problem is, but here is where Mr. Murphy comes to visit. All the screws holding the boots on are phillip head and the heads are stripping. So I start to chisel some indents into the head to get them off and the screw hole holding the boot on snaps off the head
. This sucks.

So do you think I can get away with J&B weld on it or should I take it to a welder to fix. There is no strain on the bolt.


What do you think?

I did the same thing. I was trying to be careful and using an impact driver, but I guess I over did it.

Anyway, I JB Welded it back on. But I have not fired the motor up since then, because I changed routes and put in a sort-of Bandit motor.

I'm not sure if the JB Weld route will work long-term in those heat conditions, but it was what I had handy.

I think the JB weld would make a permanent fix if you take the time to clean up the area first, and make sure and don't skimp on the stuff... they use epoxy in the floors of the intake runners on racebikes to alter the intake velocity, I'm sure that if the stuff can stay stuck there, it should be OK on the outside of the head. If it was me, I'd just use the epoxy to build up a big blob where the hole for the screw used to be, then sand/file it flat so the manifold will fit smoothly, and drill & tap for a heli-coil insert. Pulling the head for welding for something like that would break my heart (to say nothing of the checkbook).

...do yourself a favor and use hex-head or allen-head bolts in place of those lame-assed phillips fasteners when you put it back together...

Well so far so good. I cleaned it and used J&B to stick it all back together. Seems like it will hold ok.
The only part that sucks is the only replacement boots I had were stock 86 750. Those boots make it a bitch to put 36 flatslides on.
If anyone come across a set of 36 or 38 intake boots let me know.

Glad you have it sorted mate..get out there and give it some stick.well "to test it of course"...


Remember that it isn't properly test unless you've done a top speed run and at least 5 good wheelies

A guy came walking (limping) by the pits this weekend with bandages all over him. A result of a 'bad wheelie'. Doh!

<font size="2" face="Verdana, Arial">LOL ...ahhh... but was it the wheelie, or the *landing* that was "bad"?
