Fork Spring Lengths

#1 PostAuthor: Hack » Thu Sep 10, 2009 9:10 pm

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

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!!! :D

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? :roll:

Thanks

From the Kwak manual. Z1000D are service limit 533mm free length.

Mk2 are 536.5mm stock and 527mm service limit.

Interestingly the Kwak manual makes no mention of the spring spacer but my parts book does.

Always good to have more than one source of reference eh ?

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

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 ")
