Which kz750 is most similar to a kz700A?

The rear shocks are already at the stiffest. Both front and back feels extremely soft. I think I'll change the fork springs when I'm at it, if nothing else then I know they are new

Edit: Ed I'm going to get some like yours I think. Dave Quinn told me to contact Hagon UK so I'm mailing with them now.

If you look in the manual it will show you how to measure your fork springs to see if they are within service limits. Normally they do not need to be replaced. Ed
