My Kawi's rear wheel wasn't spinning nearly as free as it once did. I thought replacing the bearings would help, but now I know there's more going on.

When trying to reinstall the wheel I couldn't quite get the chain adjusters to line up with the ends of the swing arm on the right side. Thought maybe I didn't drive one of the bearings all the way in, but it turned out that there was a small gap between the caliper holder and axle collar that I had trouble closing.

After forcing the gap closed the wheel went on, but the spinning tightened up and the slot of the torque link didn't exactly line up with the caliper. When I pulled out on the top of the caliper things eased up and froze again when I let go.

At that point I noticed the outside of the disc had been scraping on the caliper, even though there is still a decent amount of meat left on both pads, which are worn evenly. The piston wasn't pushed out at all and the pad was even with the caliper surface.

Bled the system dry and took the caliper and rear master cylinder apart, but nothing obvious jumped out at me. As far as reassembly goes I've been comparing A1 and B1 diagrams, and feel like everything should be okay, but is obviously not. Maybe one of you with more experience can shed some light on what I'm missing.

Looks great so far.
Isn't that a GS1100E swingarm?

A 150 should fit fine inside that swingarm. Be sure to check tire to chain clearance though, and chain line.

If you measure from the centerline of your current tyre (or wheel rim) , with all the spacers etc in place, to the chain,that should give you an idea of how far you can go with a fatter tyre.

I have a 77kz1000 with a 81 gs1100 swingarm and an aftermarket 18in wheel that I believe to be 4.25in wide. Does anyone know if I can use a 150-70 tire, why should I or should I not go with the wider tire? Avon makes the tire in 130,140,or 150. Any help would be appreciated

May not apply to your problem, but some places to check:

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.

I have a 2000 GSX750 front end complete, and including the appropriate bearings to make it bolt on the 750 twin. I also have a 83 GPz750 swing arm converted to dual shocks with the matching rear wheel. Forks are polished and have RaceTech emulators installed.

I was planning on installing them on a 750G twin, but have been thinking about using a spare ZX12 front end instead.

.

Spark is good, and I've cleaned out carb (maybe I should re-do?). I have a new battery that's totally charged (via battery tender, not car battery), so I'll give that a try and see if things improve.

For some history, this bike was rescued from a barn in WI., so it wasn't stored outside, but was subject to hot/cold swings. Before last weekend, it had been about a year since it was started-up last, so not a long-long time, but a good while.

I have not tried to let it idle/warm up and just run for 10-20 mins. Would that potentially help clear some stuff out?

Also, it's true that the petcock is old and needs some TLC, but the gas comes out just fine. I suppose I could to a tank clean and see if that helps the situation, but the fuel filter loos good, so I'm assuming I don't have too much gunk coming from that part of the system.

Yes, this will pretty much be a off road bike.
As far as the swingarm goes, it was a bolt on. All I did was add a kz900/1000 triple tree washer to "each" side to take up the extra space. (You know, the chrome washer on top of the triple trees?)
Get two of them washers and your all set. z1wiz told me how to do it. Very easy.

If you want the clearance like I did, you'll need the police front end and wheels, then a set of 365mm eye to clevis progressive shocks. I picked up the shocks at parts n more for $99 new. Part number #06-3604
