Ahh, that makes more sense.

Nice job on the diagram, Ed - that is mostly what I was picturing. The yellow line on the left was a surprise, though: I didn't realize that frame rail was at such an angle.

I think the misaligned shocks will put a slight twisting load on the swingarm bushings as the bike goes over bumps. It might not actually bind until the shocks are close to bottoming (if it binds at all) but it's still not a good idea.

Hope the OP sees the diagram before getting the bike on the road.

Agree that battery should not be mounted to the swingarm. That increases unsprung mass among other things.

Best way I found to get the swing arm bearings out is make up a nice long tool that comes in from the opposite side of swing arm and catches on the lip of the bearing. Then with a good size hammer knock them out. The tool that I had made does not normally leave a groove when removing the old bearings. If you have any type of grooves or gouges inside the swing arm, you will have a real hard time getting the new bearings in place. The bottom tool in photo is the tool I use to remove the old bearings. If you do have any type of grooves or gouges, I would sand the inside of swing arm to it is smooth again.



The other tool is what I use to install the new swing arm bearings. Notice this tool distributes the force of pressing the bearing in place on the whole 360 degrees of the bearing edge. I insert this tool through the swing arm with a new bearing, and place a new bearing on the other end of tool to make sure the new bearing is centered as I install it. I have never damaged a new bearing when I used this tool to install my swing arm bearings. After you install the new bearings make sure the inner needle bearing spins freely inside its outer cage. If not, you have to start over with new bearings!!!!

To your understanding for the recommended tools, (bearing puller)

but how was you able to insert these tool? I mean the bearings is on both sides, you was not "draging"/hammer" it out by forceing the bearing through whole swingarm? Please see attached picture (hope you understand) so I understand you correct.

You need to get the tool beyond the bearing, but how ?

Sorry for not understand.

One question more, on partzilla it`s indicated two bearings one on each side, but as fair I can see are there 4 on my swing arm 2 on each side?

I use a blind-hole bearing puller and lots of heat.
It’s the only way I could get those roller bearings out of aluminum swingarms without destroying everything in the process.
They are invaluable for removing the wheel bearings as well.
Autozone has them in their free loaner tool program.

I need some inputs how to take out the 4 bearings inside the swing arm, please see attached photos.
First I tried to use a flat screwdriver and take it through and hit the screwdriver with a hammer.. I got out the roller of the bearings, but not the "frame" of the bearings... and then I tried to use a screwdriver to collapse it without any success, I also tried to saw it, but was to hard.

SO before I damage something will I got some advise from you people first

Please see attached photos.

Not changing things, take apart to clean up and put back together. Sent out the struts, I want to Black Chrome the frame and swing arm. Hoses, cables, are all shot and need to be replaced.
