76 KZ900 B1 - from crates.

Nice job on the tubes. I made a swingarm for a quad a while back using heavy guage tubing. I was going to buy a tubing notcher like you have, but I found I could bang out a birdsmouth in no time using a pneumatic deburr tool. I just traced a mark using a scrap piece of tubing. Use those spiral carbide bits like for engine porting.

You better believe my pics are on KZR. This link will take you to page 2 of my build: kzrider.com/index.php?option=com_kunena&...mit=20&limitstart=20

That's where it starts. Unfortunately it's all sorta spread out in my thread. If I have time later, I'll put all of the pertinant pictures together, and post them for you. Sounds like your idea is about the same way I did mine. You will probably need to do something like OMR for the upper mount. I was just lucky since the GSXR still had a double cradle frame. The newer bikes tilt the shock further back.

BTW - There is a small tab in between the centerstand mounts (about 1" tall).

Can anyone tell me what it's for? I bought this bike completely disassembled and so not sure what it's function is. My best guess is that it's the upper center stand spring mount, but would like to now for sure before the angle grinder comes out.

Thanks.

It's for the center stand spring. You can cut it out. You would have to be real creative to use a center stand with a mono shock setup.

Thanks for the tip. Is this the kind of bit you're talking about...

Bookmarked that one. Thanks.

The pictures that I promised. The first are the bushings that I made to adapt GSXR pivot bearings to KZ1000 pivot bolt.

If you look closely at the crossbar where the center stand used to be, you can see the tabs that I welded in for the lower shock linkage. !/4" thick plate was used for the tabs.

BTW don't forget that you can click the picture for supersize.

And from the side

Do everything you can to duplicate the donor bikes suspension geometry. It will have an effect on how the rear shock behaves, suspension travel, compression rate....blah blah blah. You're on track, keep it up
