One other thought - when you removed the old sprockets did you notice signs of wear of the sides of the teeth in such a way that one side had more wear than the other? I ask because the chain can drag on one side of the front or rear sprocket if the rear wheel is offset even a little due to spacers, bearings, or chain adjusters being off a little, and that could contribute to the noise. Below are pics showing my original counter sprocket after 36,000 miles. The uneven wear was caused by the bike being set up with the chain adjusters on the sides opposite where they belonged (the KZ650-C1 has very slightly different left/right adjusters). The rear wheel was only offset in the swing arm by about 2mm, so it doesn't take much to cause the chain to run out of true. Ed

Yep.

Take a look at my z900 'Stripfighter thread in my sig. I used a '95 Gsxr750 front and the rear swingarm from a '92 Gsxr1100 which uses the same suspension linkage setup. Also search for Testarossa build as well as numerous others on here.

Later, Doug

I finally bought the EBC brake rotors so I'll have to decide on calipers soon. I'm going with a gs1100 rear swingarm with a completely rebuilt, stock KZ caliper. I'd rather get some cool front calipers instead of spending the time and money rebuilding the stock ones.

Any new information since our last posts? Custom brackets for sale somewhere, etc...

Prices look about the same as bike bandit but do they ship quickly? Maybe I should expect to wait two weeks for OEM parts? Maybe because they're so old?

That is strange. They show the swing arm including those parts (which is fine) but they don’t show the parts by themselves. However – they do sell the individual parts, but you have to find the part number elsewhere. I found the 1982 GS1100E swing arm diagram with part numbers here (see 1st link) and plugged them into the Partzilla search engine (see links 2 & 3). Check to see if I picked out the parts you need.

Just checked partzilla for my swingarm caps...they show them at around the same price. Swingarm bearings are a bit high at $704 each! :ohmy: What's up with that? :blink: Spacers are over $700 each too.......

(GS1100 swingarm, btw)

Got my gs swingarm but not really sure what shocks to go with. I have a set of Werks shocks that would be perfect but they have rid ends instead of clevis. I've thought about midifying the gs swingarm to accept kz shocks but haven't been able to find any write up on anything like that. Any suggestions? If I decide to go with new shocks does anyone know what length I need to maintain stock ride height?

it will be much cheaper to modify the GS swingarm. if you don't want to make your own mounts you can just buy some and have someone weld them on. done and done. z1enterprises carry some nice ones.

Its real close...can't remember the exact measurement but that's very close. I want to say the KZ is about 9 1/4 or thereabouts. That's close enough. That means swingarms off a busa or GSXR's will work with spacers or shaving a little off...I think the arm off a GSXR1000 will work so if you can find all the parts from a Gixxer of the year to match the front-end you already have, it should make your life simpler. There will be some fabrication to be done but it looks like it will be easier then it sounded like it might be. I know they use the swingarms off GSXR's and Busa's for swaps so it should fit on yours. Maybe someone who has used one of these arms knows the exact size so you will know for sure though.

Never heard of anyone doing this to a 550 so ... first thing to do is to measure how wide the pivot tube on the front of your arm is. Then you can look for another swingarm that is same size or close to it. That will help narrow down what arms you can use. I agree it would be good to use same wheels for a matched look. Either way, you will probably have to adapt new linkage to your bike. Best thing is once you find an arm that might work would be to buy the complete rear assembly if possible. Arm, wheel, brakes, linkage, etc. Then you could start to fabricate the needed mounts. If possible take pictures of new assembly on original bike to see what angle shock is and how everything fits. I'd look at the arm assembly from your GSXR1000 to see if it would work first beings you already have the front. Or look at the 600/750 series also. You will need to start measuring to see what you have and what will work and then tear into it. It will take work but all of these types of swaps do. Lots of guys on here can help you thropugh the process once you get going...
