compression test results

[Yamabull]

What pressure should I see for a dry compression test?
I got:
#1-165
#2-180
#3-180
#4-180
#5-170
#6-180
Are these good? The engine has 175k on it.

Those numbers look fine for a hi mileage engine. An important factor is they are all within 10%, no big differences between them.

A couple of questions:

Did you hold the throttle body wide open?

How many times did you let each cylinder compress?

 

[Yamabull]

The throttle body was fully open. I let the engine crank about 5 or 6 times each cylinder.
