I need a 2nd opinion. I have been having a hell of a time getting my stunt bike to tune out correctly. Its a 94 CBR 600 F2. Someone suggested to check the valve timing to see if someone screwed it up. So I opened it up and this is what I found. The intake seems to be a tooth off, but I am not sure how perfectly they line up. Here is a pic of the intake came on Top dead center. Does this look a tooth off to you? Here is a pic of the exhaust cam. Perfect.
