help on compression with a cr 250

[cr lover]

i have a 96 cr 250 and was woundering how to find out what the compression should be with a stock motor. i did a compression test with the throttle wide open and it was 215.i was woundering what an average 250 has for compression.

My YZ 250 (03) not yet broken in gave 195 with the throttle wide open. I'm going to re-check it after a few hours riding to see if there is any difference.

my 96cr250 with like 10-12 hours on th piston and rings had 210 psi.

From Eric's book:

"A 250cc bike should have 170-230 psi (these numbers are for sea level)."
