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.

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

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.

Thanks for the link. When I went to it I remembered that I'd been there before - lots of great stuff - thanks for being so diligent about posting. I'll try to return the favor and keep a good record of my project.

I recently stumbled across this site...

www.radicalducati.com/index.php?page=catalogo-rad

Which has given me some good trestle work (not really a shocker). I just have to figure out how to make something that fits the work already done.

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 - grinder is coming out.

Yup. There's all different shapes you can get. It can run away from you though, so practice on a scrap piece.

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.

Thanks for the pics. I'm gonna get the rolling chasis back together and then see if I can mimic (at least approximately the trail and rake of the ZX-6R), before figuring out where to put the mounts in.

Here is a pic of my upper mount from the top

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

Nicely done. I may have to copy off you later!
-KR

Copy away! My top shock mount is very similar to irishwills bike. I took my inpiration (maybe a little more) from his design

Thanks very much for posting - that looks just the type of solution that I'm looking for. Which swing arm did you use? I'm still learning my way around KZR, is your build thread here?

You bet it is. My build thread is here kzrider.com/index.php?option=com_kunena&...w&catid=11&id=348089
and my swingarm thread is here kzrider.com/index.php?option=com_kunena&...ew&catid=5&id=349329
My swingarm is from an '08 Triumph Speed Triple. It's alot of reading though, enjoy
