I just completed my first rebuild, putting the engine all back together. I have installed the camshaft at top dead center on cyl 1, and to my understanding is also top dead center for cyl 4 (please correct me if I'm wrong because it makes sense in my head but I'm not 100%), now I am getting ready to do the valve adjustment before putting the engine back in the bike. After watching a few YouTube videos, I'm seeing different things. Some are setting top dead center for cyl 1 and adjust exhaust and intake for cyl 1, exhaust for cyl 2, and intake for cyl 3. Then rotating 360 degrees for cyl 4 to be at top dead center again and doing the rest of the valve adjustments left. Then other people are setting top dead center for each cylinder they are about to adjust. Can anyone clarify this for me please?
 
It can be correctly done either way.

Okay awesome, thank you! With the option of doing the cyl 1 and adjusting four of the valves, mine seem to be off and it has me very confused. I have cylinder 1 at top dead center, in between the exhaust stroke and compression stroke, and the cam sitting how it is positioned in the first place with the timing line, on the side of the cam, horizontal to the ground. But the exhaust valve on cylinder 2 is not budging, intake is wiggling a little, and on cylinder 3 the exhaust valve is moving but not the intake. Not adding up, is there something I missed here? I could adjust the valves by TDC of each cylinder but I just want to make sure nothing else is off because it is opposite of the booklet for cyl 2 and 3. Please let me know if I can clarify on anything.
 
I like to adjust them one cylinder at a time each on top dead center. Makes it easier and then you know you are adjusting them correct with no confusion.

Yeah, to be correct it has to be TDC on compression #1, so rotating while intake valve opens, then closes, then next TDC. Also the same if doing each cylinder individually at TDC. I agree the latter can be more certain than the "book method".and both valves on each cyl. should be at max lash (on the heel).
