Grahamm, as far as I know both the 1000j and the 1000r share the same forks (I think the top nuts with the air valves might be slightly different. I think the J1 and j2 had angled valves while the 1000r had valves that pointed straight up). The J3 I think also had holes in the stanchions which a balance pipe fitted over. There used to be a time you could cross reference part numbers on www.buykawasaki.com but this facility dissapeared from the site a few weeks ago.So now you have to check each part number by viewing that particular models parts diagrams which is a bit more time consuming. Maybe we should all bombard kawasaki with emails of complaint telling them to put back the part number cross reference feature. I spent a few mins one day cross referencing fork part numbers and the result was that the sliders and stanchions shared the same part numbers between the J1 J2 and 1000r although yokes were slightly different depending on whether you had J1/2 or 1000r. There should only be one rebound spring (if you mean the small one about 3 inch long that sits in the very bottom of the stanchion) per leg. Maybe the previous owner was a bit of a chubby.
Hope this helps

The J1/J2 fork bottoms are different to the J3.
With the J3 the bottom caliper mount is offset for the larger 280mm disc as opposed to 270mm for the J1/J2.
When you say rebound springs do you mean the small spring on the damper rod??
The Z1000 LTD (K) has 2 fork springs per fork leg and an leading axle.
Pasc your dead right about the J3 with the balance pipe.

Yep,2 3" long springs on the damper rod and no leading axle.the clymer manual shows 2 on the damper rod of 1000R and GPZ1100 B2 ? Any ideas ?

Grahamm,just checked in my genuine Kawasaki manual and there's only 1 spring for the damper rod.
I've got a spare manual I can lend you if you want to cross reference with your Clymer.

Ok, just checked the parts diags at buy kawasaki.com. The 1000r1 and r2 does have 2 springs on the damper rod even though the j1 / j2 shares the same stanchions and sliders the j models only have 1 spring. Not sure what the reasoning is for the extra spring. Looks like your pals J forks are indeed R forks.

Agreed Jack. We musn't forget our anoraks though

[london calling]

No can do Pasc,someone lent me an anorak and as a little thank you I sent it off to Piggy for his executive press service.Never saw it again
Rather discuss Z1000J and Z1000 R1/R2 steering head angles

Jack, sorry mate, my mistake
