CB350/400 / Cam lobe position and tappet adjustment
« on: April 22, 2018, 08:41:27 PM »
Just wondering if you could help me get something straight in my head.
I have just timed the camshaft (T1-4 marks correspond,cam sprocket lines parallel with top of barrel,cylinder 4 cam lobes pointing down)
Next job is to fit the head and adjust tappets.
According to the manual you first adjust cylinder 1 tappets at TDC with valves shut. BUT if I leave the camshaft in the same position(as above) the cam lobes are pointing up therefore valves are open.
SO-do I have to rotate crank until cylinder 1 TDC and lobes face down.If so,why does workshop manual(p20) show you cylinder 4 with lobes in down position for timing purposes?
OR-do I adjust tappets at cylinder 4 first and do it the opposite way to the manual
Am I overthinking this?
