how much compression should a crf-230 have?

year 2003!

A stock CRF230 should have @ 190 PSI with the engine warm and holding the throttle wide open.

I hope this is the data you are looking for.

well i checked my compression today, stuck the compression tool in my spark plug hole and my dad turned the bike over and i am only reading about 90 psi

by the way how do you check compression while engine is running? My compression tool go's in the spark plug hole

You don't check it with the bike running, just holding the estart button for 5 or so seconds with the throttle wide open
