    GPZ1100 cams (fit ZRX1100)

    Have a set of GPZ1100 cams that I removed from a head needing the double valve springs. Would give a nice cheap performance gain fitted in a ZRX1100 (129hp GPZ v 106hp standard ZRX in Kawasaki's claimed figures at crank supposedly) and probably a fatter midrange than you'd get with the ZZR cams seeing as they retuned the ZZR engine for greater midrange in the GPZ1100. They're in good condition, one tiny pock mark on one lobe but otherwise seem fine. 35 posted to you...

    Hi.

    Out of curiosity could you tell me which model GPZ the cams came from?

    Much appreciated

    From a 90s GPZ1100S (95-98 years), I believe the head was from a 96 model. There are some on Ebay currently if you wanted though most people use the ZZR ones these are a halfway house I suppose.

    Actually the GPz1100E - uses the same head as a ZRX with cam profiles a halfway house between a ZZR & a ZRX
