Bought a compression tester today and ran a test. My readings came out cylinders 1-4:

165-140-110-165

Just a few specifics here:

-I dont have the carbs or the valve cover on right now, but charged the battery fully before I tested

-Cylinders 2 & 3 (with the low readings) climbed quickly in psi til they got just below 140 and 110 but then would have kept climbing about 2 psi per crank if I had kept running the starter, but didn't want to strain anything. Dont know if that is an indication of anything, but figure I should note it.

If anyone has recommendations for the next step or interpretations of my readings I could really use them. Thanks!
'81 CB750K, '70 C70. As long as the Honda's older than I am, I'm happy...
