My b-bike 04 R1 had a water oil pump failure last year and overheated pretty bad. Fixed that but since then it has very low power problem I'm trying to diagnose.
I went to test the cylinder pressure and see if a valve or head gasket may be out of whack. Started with #4 good, #3 good, #2 and#1 bad like no compression...nothing! Recheck #4, bad like nothing, wait what?! Why would #4 retest fail?
Maybe the air cutoff valve is messing with my cylinder pressure tests?
Ideas?
