I don't suppose anyone has, or knows of, a spare set of GPZ750 cams in decent condition for sale please?
Cheers

Thanks for getting back to me Kev.
I don't know if they'll be what I'm looking for. I have a 650 that has been bored out to 700 and a Wiseco piston kit. I was told a set of GPZ750 cams would make a good bit of difference to the power rather then standard 650 cams. Do you, or anyone else know if your standard cams will be as good?
Cheers

unitrak cams are the best (highest lift) to go for, they're all a little different...about 0.3- 0.5 mm iirc

The 750 cams i have are 36.3mm they are the same as the zephyr cams.
the 650s are 35.8mm. so there is a .5mm difference between them.

Thanks for that.
I'm pretty useless when it comes to engines and that sort of thing, will these cams give me the improvement I'm looking for?
How much do you want for them by the way?

I'm not sure what performance they will give, maybe if you open another thread in the help section, some of the other members will be able to give you some idea of the type of perfomance upgrade these will give.
