marking on points cam

[DOUG6PIPES]

can anybody tell me , when the rh cylinder is on F on the alternator rotor with the points just opening where should the line on the end of the points cam be

The line on the points cam is TDC for right cyl. so when T is lined up on rotor the points cam line should also be vertical at top.

Keep in mind the engine is a 180 crank.
You install the cam chain with the "O" on the cam sprocket vertical to the center of the head casting and the line on the point cam toward the "O".
Now to set the timing/valves you must rotate the crank a cycle so the line on the points cam is down/vertical to the center of the head casting and the rotor is at "T". ....................lm

Just a suggestion, but as this topic covers several different model bikes, it often pays to clarify which model/year you are referring to. I have a '64 C72 and was thinking you were referring to that model, but rereading it now looks like you are referring to the CB72? This may explain why the answers are differing?

Thanks Muddy you are right, the bike is a 1963 CB72

I'm sorry too as that means I cannot help at all - the 2 points model is still a mystery to me.

Good luck.
