KZ900 - updated suspension was created by Bama704
I am taking my '76 KZ900 and doing the swap to a 2003-2005 kawasaki 636 (zx6r) front end, I already have my KZ stem pressed into the 636 triple and it fits like a glove. I need to make the decision on using the clip-ons, or running some risers, would possibly need a new top triple to do this though. For the rear I have a gs100e swingarm that I will be doing as well. Right now the fender for the 636 looks like absolute crap IMO and doesn't fit the look I want to get.

I have the GS1100E swingarm mounted up and after getting the wheel (88-90 zx10 18in.) in it looks to be centered and the sprockets align from what I can tell, but when I test fit the chain it is rubbing on the tire. If I were to do an offset front sprocket that is just giving me clearance to align the sprocket, which is already aligned so it would not help with my rear wheel clearance, right? Do I need to find an offset rear sprocket, or shim the sprocket?

Just to note, the swingarm was not a direct fit. I had to add some shims to either side and then I had to trim part of the frame where the exhaust was hanging for the stock pipe location. I could have cut them off, but wanted to retain the look. After the trimming the swingarm fits nicely now.

A few other things I have done is I cut off the key location on the upper triple tree and drilled/tapped holes on the underside for my gauge mount. Hooked up motogadget M-lock instead of moving the key location, which is pretty sweet. It is behind one of the side covers. Got the rear caliper rebuilt and sorted out, now just trying to work a location to mount my master cylinder. I was going to use the 2 bolts for the engine case but it will interfere with removing my battery. Also got the Tarozzi rearsets put on and they look great.

I’m gearing up for the same swaps. I’ll be following this. Thanks for letting me ride your coat tails. I just responded to a post from IrishWill about custom triple trees for zx6r forks. I’d like to use low rise Superbike bars and stock gauge. I want spoke rimsthough. I already have the GS1100e swingarm

I’m leaning toward these rear sets from Les. I’d like them black chrome finish. Have to ask Les if he can do that.

I'd love to do spoke rims as well, my budget prevents that right now.
Let me know how your's progresses.

This photo of Davido’s build caught my eye. See the riser mounted on the upper tree. Says it’s a ZX9 front end. I can’t find one similar

Guess I didn’t look hard enough. Now what size axle does it have

I am using the Woodcraft clip ons with a 3" riser. They are very well made, and the rise brings the bars up for a "closer to superbike" position.

Mikaw, when mocking up the mc that is where I have come up. I'm guessing that the 76 LTD had a bracket welded to the frame there. Can't find any pictures of one.
