I had to get confirmation that MotoGP Werks was remanufacturing Cal-Fab swingarms as seen in this article: www.motorcycle.com/top10/top-10-things-motogp-werks.html/8

Red got back to me, and yes indeed, he purchased the company and Cal-Fab swingarms are being manufactured once again!!!





The article is true, the price will be $599. A 150-series rear tire will fit easily.

Right now, they're only manufacturing a disc brake version for Z1s, unless they get 5 to 8 pre orders for the drum version. I'm interested in a drum brake version as I like the lines of the drum on the back of an old KZ, and I do not plan on ever doing a track day on the old bike.

I wanted to put out a feeler to see if anyone else was interested in a drum brake version as well. Let me know if you are!

Thanks!

Oops, sorry guys I thought you already new this. He started with the Gixxers and is now making one for the KZs.

The Gixxer I built for my buddy is delivered, he took it home to California. Then he calls me to tell me to pick up a bike.
He bought me a real nice GS750E as a thank you gift...

Now who out there knows of a good building Forum for the 83 GS...

This one is a survivor, no molestation has occurred. I am about 30 days from finishing the KZ, then its on to restoring this GS.

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.

Is that applicable to low speed (below 50) wobble as well as higher speed (above 50)

My kzp feels like I have a flat at around 40 through a curve

Bad steering stem bearings & swingarm bearings can create a high speed wobble

Well the latheman did a fantastic job on the swing arm pivot set up.Not sure exactly what he did but it works great.
I fitted it as soon as I got home and forgot to take pictures.Ill pull it out next weekend and post some pictures.
Anyway,it allowed me to get the back wheel in and line everything up to see how things stand.Lots of measuements,lots of string and lots of head scratching






and I got the back wheel centered nicely



Now I get a better idea of how the chain will run.


The dotted line is the center of the original front sproket,the yellow area the width of the chain.


The string is the line from the edge of the back tyre,



If I want to keep the 180 wheel Im going to have to scallop the frame. Or I go with a 160 wheel which ,fingers crossed, will fit without messing with the frame.
I found a zxr400 wheel (with sproket,disc and axle) for a good price,so ive ordered that and should get it in a few days.
Well see what happens with that.
