Swingarm swap and cleanup:

[T8erbug]

Not sure aluminum would be a good application here. I'm no pro but from all the research I have done it the past swingarms undergo a lot of twist and torsion. Since the inner sleeve you'd be making doesn't actually contact the rollers because it sits inside the stock bearing race I would think you're fine to use steel but I think anything softer than that at 1mm thickness would be pretty easily warped and crushed.

I think I'm going to have my machinist friend make up some steel bushing sleeves to use the GS 750 bolt in the 1100 swing arm. Is there anyone else here that wants to go in on some while he is making them? I could use some input on the exact width to make the bushings not rattle around inside of the swing arm, yet still allow the frame to squeeze the thrust washers/ dust caps/ inner races/inner spacer to keep them fixed. I'm thinking 224.9mm or so, maybe 224.8mm. I think the inside frame width is a hair over 225mm.

I am also thinking that making them out of aluminum may be beneficial as well as much easier for the machinist. With aluminum, we could make the sleeve 225mm, and tightening the bolt down may crush into the soft metal while compressing the frame enough to keep the inner races and sleeve fixed as they have to be. Steel would maybe make it a negligible amount more rigid, although slightly heavier

After reading Chuck's post so far, I think the way I did it was easier. A bit labor intensive though everything aligned, fit and is tight and the inner swing arm bearings are on the stock race. My machinist looked over my inner races and said, I wouldn't even attempt to try and match those especially material wise.

Yep, so you'll need a longer chain. I did the '82 1100E swing arm and 530 conversion - forgot to take that onto account. Doh!

I'm also doing this mod. What size 530 chain will I need to get if I do a 530 conversion with the 1100 swing arm? I'll be going with a 18/49 sprocket setup too keep it as close to stock as possible. How many links will my chain need to have?

I ordered a 120 link high quality 530 chain so I had some wiggle room getting the right length set up. I don't remember right now, I think I took out 4 links. Don't bank me on this, you'll have to check your set up.

Once you get the sprockets on, just make sure they snugged down though not tighten down yet. mount your rear tire on the swing arm and push it up all the way forward. Tighten the axle nut up some so it doesn't slip back. Take your chain and wrap it around the sprockets. On the back sprocket, align the ends and see how many links over lap. Now loosen the axle nut some and pull the tire back until you get some space between the adjuster and the front of the slot in the swing arm. Check where your links are. You want just enough slack in the chain where it can be adjusted some on the adjusters once installed for good. I believe I had about 1/2 space between the adjuster and the front part of the slot on the swing arm. Take off the excess links. Install your master link adjust the chain, lube it and go ride. Oh yeah tighten every thing up first lol. Torque specs, lock washer tabs bent down front and rear sprockets, new cotter pin and all that jazz.
