750 GPZ cams

could someone post all the cam specs for the 650/700/750 fours, I when to the kawasaki site and the numbers are mostly the same for 700/750 is shows the numbers for GPZ cams but only the exhaust is different and the numbers for the 700 are the same for the gpz, another site says the 650 cams are 306lift and gpz is 354lift another site says 750 cam will beef up a 650 and gpz cams will be an upgrade for all mid fours, I would like to know for sure, as I just purchased some GPZ cams, so does anyone have the exact specs

Did you see this thread?

Specs are in the Filebase, as noted and linked in the thread mentioned above.

so what I understand is that 82 GPZ cams are the same cam as the KZ750 cam nothing special, the chart gives duration but no lift, I did a lot of car engines and when I pick a cam I look for lift as well as duration, this usually will tell me the personallity of the engine,I'm kind new to the cycle engine but its just an engine and all the rules apply, it seems that compression plays a big part in the four stroke cycle engine,if the kz pushes 74hp and the gpz pumps 80 with the same cam then a half point of compression bumps it 6hp thats significant,so in a 650 with a 750 cylinder bored to 810 with GPZ cams(kz750) port job and carb jet with the 10.25 pistons and header I figure around 90hp,usually in a given engine you will find there is a point to where HP is easy to make then it costs a ton to make any more

I wouldn't put too much faith in factory claimed figures.

yes I know, just a theory on paper,but you have to start somewhere

I'd bet that the figures published by Kawasaki are actually pretty accurate.

For a brand new motor properly broken in and tuned perfectly, and measured at the crank, and with everything in perfect condition, and tested under ideal conditions.
