Looking for a very good crankshaft, anything with the small alternator nose would do, needs to be in excellent condition or rebuilt, welded too would be good. Just inspected my crank and there's some rust damage on the where the outer bearings run, so it's a no go. Please let me know if you have something, even it's a damaged crankshaft with good outer webs that I can use, I have an hydraulic press. Will pay decent money for a known good one. Thanks, Mick

Still looking for a rust free crankshaft with minimal wear if anyone has anything, also the outer bushes or races with no pitting, anything useful, even damaged. I now have a supply of high quality German needle rollers to refurbish the outer crankshaft bearings if anyone is needing them. I can press out the old rollers and fit new rollers to your bearing cages. P.M me if interested, seems that the complete bearings are no longer available, unless anyone knows different?

Hi Mick,
Crank journal and big end bearings are available from Japan.webike.net Just type…..kawasaki z1 voice….and you should find them easily enough, but it gets a bit spendy though.
Connecting rod bearings are about £28 quid each and you will need 4.
Journal bearings are about £25 quid each and you will need 6.
By the time you add postage, given Rachel her customs duty and vat, it stings a bit.
Im sure you will find a suitable crank somewhere.

Thanks for the info, I don't need the big end or crank bearings as I removed the old bearing rollers and fitted new rollers into the cages, I mentioned this in case anyone else is looking to replace theirs. Still wanting a clean crankshaft or any good parts, thanks, Mick

Hi Rob, is a Z1r crankshaft the same as a Z1 crankshaft, or same as Z1000A1? The reason I ask is, I have a Z1 crankshaft, which I haven't pulled apart yet and was hoping to find another the same so I can build one good one out of the two. I am interested though, cheers, Mick

The Z1000 and Z1r are the same, the Z1 is different (lighter).
