That looks like it should work. Great price! Ed

Ok so do to having more money than spare time, I'm looking into other options in regards to building my bike. I've got a79 kz400. I was originally goin to stretch the stock swingarm myself but as I've said, time has been short for me.

Now as I understand it thanks to lurking around, a gsxr swingarm is a likely candidate for a swap.

First, is this true?

Secondly if it is, will it really matter if its from a 600/750 or a 1000?

Thirdly, what kinda issues can I expect to run into and what else will be necessary to make this swap? I know the obvious things like wheel, shock and links. But what else?

Thanks in advance guys.

That's why I couldn't find them! Was looking for "bushings" not "bearings". Thank you immensely.

Good news! The 1979 KZ400 does not use swingarm bushings. It uses needle bearings and they are an "Active" part,so they are still available from Kawasaki. Partzilla lists them at $9.30 each (needs 2). Ed

Well, got it back from the sandblaster, got it in primer and did a test fit of parts to throw in a 9 inch extended swing arm. Things have come to a screeching halt do to a move to bigger shop. It doesn't look like I'll be riding the 4th of July. As soon as the move is done, it's back to the KZ. Thanks for watching guys....

Sure I'll post it for you.

These fit a lot of the Harley models, I think that's why they were set up with the heavier springs. Such a small and simple part, but what a freaking difference over the dampening rod factory set up.
Don't forget to replace your steering head bearings, have a close look at the swingarm pivot bearings also. I replaced all of the above. Also under braced the swingarm while it was off. Tried the Progressive rear shocks, with a couple of spring rates and while they were decent enough, I ended up switching to a set of FOX Racing Shocks. They are 14" instead of the 13.5" eye to eye, which made it a bit easier to get on the center stand when the Vetter Bags are packed on.

I'm doing a rear swap on my bike soon, I'll have the full rear end off. Swingarm, wheel, brakes, shocks. Do you need just the wheel, or the whole deal? My bike is the '78 C2 model, spoke mags

Picked up the 600 swingarm yesterday. It needs some cleaning/polishing, but it'll make the whole process MUCH quicker to do the swap. Hopefully some shop time this upcoming week over an evening to get things started. Pictures will follow

When adjusting chain slack, owners commonly use the crude rough markings on the swing-arm to align the rear wheel.
A more accurate alignment within the swing-arm may be achieved by confirming equal distance on both sides between the swing arm pivot bolt and rear axle (measured between center-points).
Such alignment should also result in perfect alignment of the sprockets so that the chain runs straight and true between the sprockets.

Ideally, when the bike is rolling straight forward, the center-line of the rear tire will overlap the center-line of the front tire, but overlapping tire center-lines isn't critical, whereas perfect alignment of the sprockets is critical.
Many fat-rear-tire bikes, including factory showroom models, don't have overlapping tire center-lines. But they are all supposed to have perfect sprocket alignment.



Good Fortune!
