I picked up an ugly CB750 for Freeeeeeee.
I started going through the motor checking spark and compression and came across something strange. Cyl 1,2,&4 all show 135-140. Cyl 3 shows 235+ psi compression.
What could cause it? I pulled the valve cover to see if I could see if the exhaust valves are openings but everything seems to be in order with the cams rotating and the tapets rising after the lobes press them down.
What am I missing?
