we put a new rear on my 900 cause it picked up a slice.....and even though my old rear was the same (avon roadrider) and was only a few months old,and even though i ran 36 psi in both,and even though my shock settings,chain adjust marks and all else is set exactly as it was on the old tire.....
my bike is completely different feeling than it ws yesterday in the rear.....it feels like i clicked my koni's up to passenger settings and is way smooth on tracking setting into freeway sweepers and 90 degree in town turns.....
go figure...see what it feels like in 50 miles....

Also just because they line up on the marks doesn't mean the wheels are in perfect alignment. The shocks may not be equally compressing, the fork seals? have they been leaking. Too many factors at play here. There is something going on for sure and I would bet it is the tires being old and decrepid but you are a mechanic and I would assume you know and have ruled out those things. You weren't a Harley mechanic were you?

Hello again...
Although I have been working on Bikes for 30 years and consider myself a fairly competent mechanic who will take on most things I have never owned a KZ before and they sure are a little different to most other bikes I have ridden.
Handling wise, my KZ1000P feels like it is going to be a pig at low speed yet is as agile as any bike I have ridden, the tires are Dunlops and hold the road well, yet will 'track' the slightest groove in the pavement making the bike sometimes feel as if it is bendy in the middle.
My main concern is over 70mph it feels as if I am riding on ice, the bike is very "squirrely" and feels 'loose'.
I have checked tire tread and pressures, the head bearings are fine, no notchiness or stiffness, the swing arm bearings are OK, the rear shocks seem fine as do the front forks.
Is it ME, or do they all feel this way? my old DR650 was rock steady at 80-90mph but there is no way I want to do these speeds on the KZ, she feels happier at 55-60.
Any ideas Guys??

I do like 650ed does to balance the tire and wheel assembly, except that I use two cinder blocks, standing on end. Then I place two 1" x 2" pine strips on top of the cinder blocks and under the axle. As the "heavy spot" settles to the bottom, I slightly roll the axle back and forth. This allows the heavy spot to more accurately find the lowest point. Mark that spot. Repeat the exercise several times. Then start adding weight opposite the heavy spot. Trial and error until the tire will stop at any spot and not roll.
Good luck.
