Hi,

I am new to this forum. Picked up 2 69 Z50's. Can someone tell me what is the stock cylinder compression range for these bikes?

Thanks,

Tim

Between 120 and 180 is good for a stock motor. I've had a motor that ran with 80 psi.

168 psi as per manual, as arlindsey said, 120 to 180 for a healthy engine.
