Does anyone have a genuine Kawasaki manual which gives the correct standard fork spring length for:-
1978 Z1000A2 / Z1R (Z1000D1), KHI Part Number 44026-1003
and
1980 Z1R (Z1000D3), KHI Part Number 44026-1039
No guesses or assumptions please, and I don't need the lengths of any models other than those above.
I'm also after the length of the spacers from above the springs on a Z900A4 or Z1000A1, so if anyone has one lying around could you please measure it for me.
Thanks in advance

Fork Spring Lengths

I`m guessing that the spring free length is 521mm with a service limit of 511mm. That is for the 1000A1 with part No. 44026-071.
Don`t know what you mean about a spacer on top of the spring. Could it be they are aftermarket additions to increase spring compression ?
I had some of those on my LC back in the day !

I said no Guessing!!!
You are right about the part no. 44026-071 being used in the Z1000A1 and that part is also used in the Z900A4. In both cases the standard length of spring is 465 and a spacer is fitted above.
All I want to know (from a genuine kawasaki manual) is:
Z1000A2/Z1R(Z1000D1) spring length.
Z1R(Z1000D3) spring length.
Z900A4/Z1000A1 spacer length )part no. 44028-039.
Am I the only true anorak left?
Thanks

Sweptail - thanks for the spacer info, 40mm makes sense as the Z900A4/Z1000A1 springs are 40mm shorter than the Z1A/Z1B springs which do not have a spacer.
TLC - Not sure that's the "D" that I'm looking for.
So I'm still after:-
1978 Z1000A1/Z1R (Z1000-D1)- these have the same springs.
1980 Z1R (Z1000-D3)
Thanks guys

Re: Fork Spring Lengths
Thanks for this I'll check them out. M7 72 Z1 is so difficult to get on the centre stand as I think there's wey too much sag (About 2 ")
