The GSXR 1000 Front end. I had Leon drill holes so I could mount Rental Fatbars.


The Swingarm, and Rear Shocks.

Here is the bike after the front Conversion (Thanks Leon) and the Swingarm install. I was wait for some reasonably priced ZRX rear shocks to come on Ebay (I waited a while).

Hello Guys, My name is Donnon. I've been lurking around here for a bit. I finally have enough courage to post up my "project". I am in no way a mechanic, but I'm not bad with a wrench and tools. I've learned so much here and I want to thank you all. My bike is a 1980 KZ750, which was in pretty decent shape. I know some may be upset because I plan on changing the bike so much. Anyway, my plan is to use a ZRX 1100 swing arm, and a GSXR 1000 front end. I want to thank Leon for the awesome job he did with the Triple Tree conversion. I will be out sourcing more work to him. I only wished we lived closer. I will try to keep a photo log as I go. I've been working on this bike for about a year, and the reason it I work overseas most of the time so I do what I can when I'm home. Once again I want to thank everyone.

I copied this from a post from Jeff Saunders (owner of Z1 enterprises)

Motorcycle Wobble Causes

There's a LONG list of potential area that can cause this.

These are not in any particular order

Wheel bearings

Steering bearings - repack grease, check tightness

Swing arm bushings/sleeves/bearings - replace if worn, repack grease

Fork springs aging - check spring length

Unequal fork oil - if seals leak, then your damping can be ineffective

Rear shocks aging, damper leaks - if you have oil leaking from the seals, the damping is toast.

Worn Tires/Mismatched tires/tire pressures/wrong size tires.

Wheel alignment - don't trust the chain adjusters - I visually align the wheels.

Bent rims/broken spokes - get the wheels off the ground and spin them - check for runout / damage

Front disc warped - check for runout

Steering & swing arm bearings are very common problems, but so are tire issues (pressure/mismatch) and wheel alignment.

Not having a front fender, as it helps stiffen up the forks. I’d suggest a fork brace.

It appears that most of you are using the needle bearings in the swing arm. I have these bronze bushing left over from another project. Hate not to use them if there is an improvement to be had?

I've looked at a few universal steering stabilizers on ebay, but how would they mount to the KZ? I have an original Lockhart 4-row oil cooler on the bike, that I may not even use because it looks like it would interfere with out locating it. What are you guys using?

Also, Steering head bearings and swing arm bushings. What are you using as well? Any help would appreciated again!

Your 77 should have single needle bearings on each side,78 went to the double bearings on each side on 1000 series bikes anyway.

Motor Head, I'm interested in Fox shocks that you used? Also, the swing arm bracing? Any pictures? Have any of you guys used the "Bronze" swing arm bushings?

z1wiz hooked me up with a 78 KZ1000 frame and some 76 Z1 cases to replace the cases on a extra motor I have.
So I put the LTD back together and mocked up my bike with the 78 frame.

***PARTS LIST***
1978 KZ1000 frame
1976 Z1 motor
1976 bodywork and controls
1980 1000C triple trees
1982 1000P forks and rear wheel
1980 KZ1300 front wheel
1982 GS1100 swingarm

OK. I pulled the wheel from the Bandit today and tried it and it looks pretty good.The 3 spoke mag design fits with the ZX9r front good enough.


But I dont see how I can get it to work. The swingarm is centered in the frame (so the twin shocks will line up)
and the wheel is centered in the swingarm ( Itll need a fair bit whacked off the sprocket carrier to do this)
So you would think that the back end would line up nicely with the rest of the bike.
Not so.
Swingarm and wheel lined up

Sprocket carrier will need a shave

Nothing lines up with the overall centerline


Back to the drawing board then.
First, I reckon I should check the frame and be very sure its not bent .Im pretty sure its not but Ill check it anyway.
Then there are 2 possibilities. Either Im going in the wrong direction here ,with the GS1100 swingarm ,and this is never going to work.
Or, Im missing something.
This is the first time Ive done this and Im just making it up as I go along. I have NO IDEA what Im doing !
I am staying positive though and Im confident that itll all work out.,I just need to get past this back end issue.
Any advice would be appreciated.

looks great! You are right, it is at least 10 times harder than it looks. But in our minds eye, the final product is worth it!
Would be nice to have a small CNC machine, lathe, drill press, pedestal grinder, right in my garage!!
Getting tired of replacing file handles!
