No, there is more to it than that. For years GM made a two stroke diesel engine that was used in many city buses. The compression was about 22:1 or twice what a car engine would be. You could smell it almost before you saw it coming.
The fellows that post on this forum are very "with it" when finding out things using internet search engines. Ask the question and give the year and make of your engine. No doubt you will get the information you need.
yeah this motor is an 04 yammie 2stroke f40 3 cyl and they are all reading in the 100's - the number just seems low to me as I am used to hearing 125 -145. I figured I would put it out here and see what you guys have to say on the subject. I guess I was a bit vague.. Sorry I am a bit of a noob when it comes to mechanical things
I can live with compression readings over 100 psi on a used 2 stroke.
As long as all cylinders are reading the same plus or minus a few psi.
A hot engine will give different readings than the same engine cold.
Also a "wet" compression test will give a different read than a "dry" test.
yeah this was on a very cold motor this morning I didnt have it running for any amount of time today at all and basically was just sitting there when we did it this morning around 9:30 am after a nice lil frost here in New Port Richey..
