So on my 1989 Suzuki gs500 my compression test read 0 compression on both cylinders. It's weird though cuz when you turn the engine over you can feel air coming out of the spark plug holes....I was sure it had low compression but 0 blew my mind. I will obviously have to take the top end apart and see what is going on. My question is do you think it is possible to work on the top end and probably the pistons without removing the engine from the frame?
