congrats on finding a good swap candidate. I think the older gsxr were some of the longest usd forks you could get.try and locate a member by the name black banshee. pretty sure he may be able to help you with a stem swap?as far as the swing arm first measure the frame width at your swingarm pivot bolt.with axle and wheel set into place try and locate swing arm at tire center line. you will either need to remove material from swing arm and or have some bushings made. also will need bushings made to fit over your stock pivot bolt.that bolt will need to fit swing arm.from there there are options for rear shock mount.for easiest conversion I would suggest using as much of the gsxr components together.wheels, axles ,brakes, master cyliders, rear sets,etc..good luck. and take your time.pretty much anything is possible. just look around this site. there are some pretty nice examples.

Crap...just lost a logn post !

Anyway...thanx for all the nice words.

Here´s some pic´s of the last days progress.

Old swing arm attaching brackets.



Made some new bushings to center the new bolt.












Drilled two new holse to make the rear end 1 inch higher.



New oilfilter installed



Yellow paint marking that bolt is tightend propery.

Do you mean swingarm bushings ?

The chain adjuster parts are the same on both sides, according to Kawasaki.com. I have some problem getting the adjustment set just right, as my old eyes have trouble seeing the marks on the swing arm real well. Thanks!

Sometimes the swing arm marks aren't entirely accurate.

Alignment may be verified by assuring that the same measured distance exists on both sides of the bike between center point of the swing arm pivot bolt and center point of the rear axle.

Where feasible, may also sight (from rear of bike) down along the top run of the chain as it leaves the drive sprocket and mounts the counter shaft sprocket.

The alignment should be absolutely straight as an arrow, with zero defection as it leaves the drive sprocket, with zero deflection between the sprockets, and with zero deflection as it mounts the counter shaft sprocket.

Good Fortune!

Carefully measured today and as you say, the swing arm marks/adjuster slots are a little off. Makes me feel stupid that I have been riding this bike for 25,000 miles with things in the drive train not lined up right. No telling how much extra wear that takes out of the chain/sprockets and rear tire. Thanks!

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.
