you would have to replace the output shaft with one from a z1000j or gpz1100 as they are different

For the J style non kickstart engine .
You need -
Gpz output shaft (better than a J as it uses a large nut for the sprocket retention insread of a bolt)
gpz/j gear selector shaft.
gpz/J inner cover/seal holder.
gpz/J sprocket cover.

But beware, you can't use the input-shaft, as it's longer. Just did this with my Z1000J, because I got hold of a set of Z1100ST cases and you just swap all the bits from the J to the ST and voila you have a beautiful engine.

Cheers,
Greg
There's no replacement for displacement!
