Hello everybody. I just found your forum and I'm hoping you can help me. I'm "baffled".
I'm restoring a 1974 CB450 and in the process of removing the cam bearings to polish them I managed to get the cam timing off. So, I broke the cam chain and have set the cams several times now according to the HONDA service manual and every time I button things back up, when I try to turn the engine over, I have valves hitting pistons. I'm setting the crank on LT, and lining up what I believe to be the marks on the cams but it will not work for me. Ive even tried rotating the cams 180 degrees, but still no luck. Its really hard to tell what is a timing mark on the cam and what is a casting mark. Any ideas? This is nerve wracking!
