This weekend I was adjusting the pushrods on my 85 EVO and I was trying to find TDC on the compression stroke per the instructions in the self help section “Adjusting Pushrods”. My best friend (also my wife) is sick so I didn’t have anyone who could turn the back wheel for me while I placed my thumb over the spark plug hole to find the compression stroke for each cylinder so this is what I did:
1. Remove spark plugs
2. Jack up rear wheel
3. Seal both spark plug holes with wide masking tape about 6” long and
secure end of the tape to Rocker cover as a precaution. I pressed it into the plug holes with a socket to get a good seal.
4. Turn rear wheel in a high gear and when you hear a pop (tape breaking the seal) then that cylinder in starting its compression stroke.
5. Turn the rear wheel a little more to get the piston to the top of the cylinder
I hope this isn't bad advice but it seemed to work for me - Bob
