Need compression specs for 03 YZF450 ???

Can anyone tell me the acceptable specs for the cylinder comperession on a 2003 YZF450 ? Thank you for any help.

With the Auto decomp cam I dont know how you would check compression on a YZ450? :cry:

Cranking compression??? you want to know or the spec head compression. The head is a 12:1 conpression ratio. I'm not sure what the cranking compression is. I've never put a gague on it. LOTS!!! lol..
