I'm not familiar with that specific bike. Maybe you can grind down the outside of a box end wrench, thinning it out and use that? I've done it before, but like I said, I don't know exactly what the situation is without a pic.

cut the nut in half with a dremel tool. it's probably not overtight but corroded to the stud.

Put some liquid wrench on the threads and let it sit for a couple minutes. Then put some more and use a vise.

Good luck.

find some "KROIL" or "PB BLASTER" in that order, and get yourelf some of the MAP (yellow can) gas it gets hot fast. het the nut up and give it a spray with the oil (do not inhale). give it a half ohour or so and give it another shot then see if you can get it loose.

do not forget to threaten the little piece of (^&(^ as this seems to scare it off. you may also be able to find a small set of vice grip or mole grip brand locking pliers. those off prand things are junk and only good for keeping the tech manual from blowing away

If you grind where the red is, you should be able to squeeze the wrench in there. A six point box would be ideal. It's alled "homemade special tool". Snap-on sells thin walled box end wrenches.

yeah i thought about sanding it down, the close end side and maybe it would fit...but i think ive decided to just use a rotary tool and cut a slit in it
