If you're talking about the swingarm pivot bolt that goes through the frame and the engine, you have to kind of wiggle the swingarm from the axle side (helps to remove the shock arms, too) so that you can take the wieght off of the pivot bolt. If it is still stuck, you might be looking at a bent bolt, or possibly seized bolt (then a BFH might do the job).... Both of mine came out quite easily once I removed the weight from it.

Lay your bike down and fill the bolt recess with enough WD40 to create a pool and leave to soak overnight. If its not bent, then it should come out real easy.

Use "PB Blaster" instead of WD-40. It's made especially for freeing frozen bolts. I get mine at Discount Auto Parts.

Fryboy....that trick has saved my a$$ so many times with recalcitrant bolts. First time I used it I built a little dam out of playdo around each of the 6 spark plugs of my 6 cylinder merc (74 280SE with blue vinyl seats....). The garage couldnt pull them during a service :thumbsup:
I sweated a bit myself trying to get them out thinking the garage guy was an idiot :lol:, but they were all well frozen. :awww:

Next morning I pulled all six without even trying.

I'll second the vote for PB Blaster over the WD-40. Amazing stuff it is :thumbsup: Used it many times on stuff others had counted as stuck solid. It has to be seen to be belived. :awww:

You gotta servise the swingarm bearings every 3 months or it will sieze. I let mine sit over the winter and the bearings were toast in the spring. I'm sure you will find your bearings are toast as well.

Some times these things sieze so bad you have to use a sawzall to cut the swing arm off.

Good luck

Get a pivot works kit and some 7/16 (I think) (12MM) bolts 1 inch to 6 inches long and some washers to drive out the old bearings and pull the new ones in.

I just did the job 2 weeks ago.
