I have a '99 CBR 600F4. A spark plug blew out of the cylinder head a while back and I finally got my bike put back together again. I had it pulled apart and put back together once, but realized my timing was off and had to pull it apart again to fix the timing. Anyway it starts and idles fine, revs up fine, but there is a stupid amount of valvetrain nosie. Not just a little bit like it needs to warm up, but an excessive amount. Maybe i'm not getting oil pressure or something? Or maybe I didn't properly torques all the bolts? I made sure that all the shims were put back in the correct spot. Is there anyway that I can check for oil pressure? Or any other ideas why i'm getting so much noise?
