Stripped tank bolt

Hey guys... I decided I would try to do some maintenance on my bike while I wait for my new chain and sprocket set to come in the mail. I tried removing the 2 front bolts that hold that tank on but with my steering damper in the way there wasn't much clearance. I tried to remove the damper but those bolts are stuck too.

Anyway I used some pliars with my allen wrench to try to remove the tank bolts, I got 1 out but the second one just never gave and ended up stripping.

What can I do to remove this bolt and replace it with a new one? I've tried the extractors before with my car and it ended up snapping and I wasn't even able to drill through that!

If I took it to a Honda dealer would they be able to remove it without messing up my threads or anything?

I'd love advice, I've always had bad luck with stuck bolts.

Got a photo of these bolt heads, just to see how buggered they are?

I was thinking of cutting a notch in it for a flathead and trying to back it out with my drill. Would this be a good thing to try before going at it with a extractor?

That would probly be pointless, you need to hit the head of the bolt with a hammer to shrink the Allen head hole and then drive the Allen wrench in with the hammer for a tight fit, a little heat and penatrating oil might be of some use too.

Man I'm not sure I would notch it. Doing that would severely weaken the bolt and it just might snap off.
I had alot of success using torqx sockets. They look like an Allen but have more points. Tap a slightly larger one in place and it will have alot more bite.

I recently used an extractor product by the name of "Grab It" from Lowes (click me for linky) to remove a stripped bolt and it worked flawlessly. It was less than $20 IIRC and came with a few different extractor bolt sizes (was sick of borrowing friends' extractors so I finally purchased a kit to add to my tool collection).

IMHO, I'd use an extractor and order up a new bolt from one of the many microfiche parts vendors...g'luck !

If you are handy with a drill, just drill the head off. After you pull the tank and damper mount, you'll have plenty of room to get vise grips on what's left.




I'm always right.

I tried an extractor but it snapped. I really hate using them I've never had much luck. Going to see if I can drill the head off and if not I'll take it to a machine shop and see if they can drill it out and retap it. Any objections to that last part?

Drilling it wasn't gonna happen so I whipped out the dremel. Right when I was almost finished cutted the entire head off I tried to get it out with some vice grips and it busted loose! I've never been this lucky
