This is an old Kawasaki GPZ 1100 '82. It's a friends bike and he askeed me to put on a 5,5"x17" rear rim and an up-side-down front. Well.... i took the challenge, 'cause my tickets to Australia cost (a lot).

Ladies and Gentllemen, i introduce you, the Kawasaki GPZ 1100.

Of course, the 1st think you do is to disassemple. I started from the rear arm. It was an after market on it. Nikko Baker from Holland.
Image

You can see the differences between the 2 rear arms. The one i purchased it's from Suzuki gsx 750 (on the right). It's with double shock absorbers, and will do just fine for our job. The owner wanted to keep the suspension that way.

Image

After only slightly mods with some bushes, i kept the original rear arm shaft from the GPZ and put the GSX rear arm on. Looks better ha?

Flatside carbs and now a modern suspension, huh? Nice. You keep good company.

In order to allign the engine and rear rim sprockets, i had to narrow the rear sprocket mounting at 12mm

Image

After that, i turned to the front end.

Image

Which finally disassempled

I started today the work on the front end. This is the triple clamp of the up-side-down. Its' shaft doesn't fit on gpzs' frame though.
Image

So i made a new shaft, that could fit both the triple clamp and frame.
Image

Look at the differences
Image

I took off the old shaft and put the new one.
Image

Then i gave it a very good welding, with George helping me
Image

Ready to fit in
Image

That's the way gpz looks like now. (Nikos helped me take this shoot).

Im doing something similar to a 1980 Yamaha XS1100. Shaft drive>chain drive conversion. R1 forks, single sided swingarm. Right now, its just a bare frame on the patio and a parts bike stuck in the back of my jeep until my lazy friends come help me unload it.
