a good narrow tire will definately outperform a bad fitting wider tire .im not sure about the cheng-shin tires but it depends on how hard you ride,i have used there tubes before with no problems though.like wg said ribbed tires were the thing in their day but so was disco and 8-tracks:whistle: if you want to improve the handling of a Z1 tapered steering head bearings and a needle bearing swingarm are good starting places. goodluck,happy wrenching!

I will post some more pics as I go. This weekend I have of list of things to do, or at least start to do. I need to finish the swingarm work (I had to cut out the center of the pivot point since the frame goes inside the swingarm, opposite out KZ's that the frame goes on the outside of the swingarm), cut down the steering stem, find bearings for steering head, mount rear sets, weld mount for mono shock, make seat, figure out how to mount a hydraulic clutch, make head light mounts, make fork brace, offset front sprocket and shorten rear sprocket carrier so that they line up with each other, paint, powdercoat, make exhaust and a few other things. But besides those things, it is almost done :S

Or z650 frame and bodywork, gsxr1100 motor, single sided swingarm, upside down front forks with underseat exhaust might also be good aswell. :lol:.. Maybe next time

I suspect that the numbers are the sizes of the bearing. 22 mm O/D and 16 mm I/D.

You should be able to cross reference them with any bearing manufacturer. Most if not all of them make metric bearings. SKF are italian and should have a direct cross reference, NTN are Japanese same story.

i tried it but i don't think it will give you modified lengths. the stock chain for the kz650c is 102 but the gs swingarm adds a few inches.

steel is right on the Kawi part# (92046-1115), and the bearing manufacturers part# (HK2216) as well.
Although I can't remember exactely who the manufacturer is.
The bearing size is in the manufacturers part# itself - 16MM.

If Jeff at Z1 doesn't have them, whatever you do DON'T buy them from a Kawi dealer!
My local Kawi dealer wanted $12 each for them lil buggers!
I hit up a local bearing supply shop that I've dealt with before when I replaced the ones on my 650, and scored all 4 of them for $24 - half the price the dealer wanted for the EXACT same bearings.

If you can find a well stocked bearing supply shop near you, they should either have them in stock, or be able to fetch them from their main warehouse/supplier.

Good luck.

I have a KZ650C with the GS1100 aluminum swingarm and I had to go to a 110 link chain. 114 links will be to long if you are using the stock sprockets.

i am wondering if anyone with a gs swingarm on a 650 can help. i was wondering if a 114 link chain would be long enough with the gs swingarm.
