My mate has a vn 304, running 10-1 compression.
If we did a compression test, what should the results be around?

About 170 at a guess, depending on what cam is in it (but a correct cam for 10:1 will be about 170)

to do the test you pull all the spark plugs and fit a pressure guage to each spark plug hole one at a time and crank the engine over with your foot hard on the throttle.

Well really you could, but it would take lots of math :)
