Recently bought a CB450 with an intention of rebuilding it. Just did a cold engine compression test. My first time doing a compression test, just following instruction that came with the tester kit. With throttle open, kicked it (kick starter) 4 - 5 times and it reads about 75 psi on both sides. Is this normal? or am I doing the test right? I read in some other posts, it needs to be somewhere around 150 psi. Would appreciate any help. I'm not exactly mechanically inclined, just trying to learn as I go along. :|
