Hi all,
Just fitted new piston rings, refreshed all the engine gaskets etc, and thought while I was waiting for a new battery to be delivered I thought I would do a cold compression test.
No spark plugs in.
Full open throttle.
All carbs and air cleaner attached.
No battery so used the kick stater.
Think the results seem promising. Cylinder 1 155psi. Cylinder 2 150psi Cylinder 3 155 psi Cylinder 4 160psi
The compression on a warm cylinder according to the manual is 170 psi
Does a cold test give accurate readings or will the true condition of the engine compression only be found when a warm test is Carried out.
