GPz750 forks on a KZ650??

I am reading some posts that hint to using GPz750 forks on a KZ650. Is there an advantage to this? Is it a pretty straight forward swap?

Thanks in advance!

If I'm not mistaken, pz1morton has GPz forks on his 650 he races.
He hasn't been on the site in 4 months though.
I have his email I believe. I'll see if I can track him down.

Here's the answer I got from Paul:

Yes my race bike has a gpz front end & rear.for me it is a very smoother ride and better into the corners.if the person was to go on allballsracing.com they could punch in all the info and it will give them the kit number.at the time they had to make mine up.they could also phone and talk to Kevin [ great guy ] very helpful and knowledgeable too! 1-610-473-0505.it also depends on what year he is trying to graft on to a kz650.

Thank you for the info..
