Topic: finding copression stroke

[pepsoy]

hello. with the tappets totally slacked and the valve cover on, how do you find the compression stroke on the 1 or 4 cylinder (valves closed) when the tappets are slacked and  all valves are completely closed. or does it matter? do you start with the 1 cyl at the T mark just bc it's first and go from there for the adjustment. i guess it's 50/50 on getting it right!

    Even with the tappet adjusters completely backed off, the rocker arm paddles will hit the cam lobe. You can pinch #1 intake rocker between your fingertips and feel it rise and fall as you spin the engine. Spin the engine until you feel #1 intake begin to rise, then look at your timing marks and spin the engine to 1-4 "T" mark. You are now on compression stroke for #1 cylinder and can set gaps for..

#1   intake and exhaust

#2  exhaust

#3  intake

 Spin engine 360 degrees(one revolutuion, returning to the 1-4 "T") and set gaps for..

#2  intake

#3 exhaust

#4 intake and exhaust

DISCLAIMER:  I may have the specs for #'s 2&3 cylinders reversed. Please consult your manual before proceeding as I am just going from memory. Process described is for a CB750

Sean, I can actually wiggle both rocker arms on #1 when it is TDC on Compression stroke.
