What is a good compression test result for a kz750 4cyl? How much difference in cyclinders is acceptable? Thanks in advance for the knowledge! I'm looking to replace instead of rebuild my engine.

150 to 170 is good, anything down to 110 is drivable, should be no more than 10% difference between the highest and lowest.

This is not what I wanted to hear but Rice Paddy has no engine that would compression test good! I guess I'm back to searching for another source.

Search for a member named smithgpz and e-mail him, it's been a long time since he posted so I doubt a PM will work.
He is in Columbus and might be of some assistance.

I will do that. I'm not beaten yet! I started scanning the classifieds for another whole bike, thought maybe I could find one in poor shape but with a good engine. Thanks again for the lead.
