Hi everyone I'm new here I was recently given a 1976 honda cb500t and have been working on it so it will be my first bike when I turn 16 in a month. So I pulled the motor out rebuilt it using newer used pistons with 10,000 miles since my bike has 28,00 and the motor was seized when I got it. I honed the cylinders and put standard size rings on the newer pistons. Put the motor back together with a new cam chain and didn't really do anything to the head except for clean it up and throw it on. I then painted the motor gloss black and put it in the frame and did a compression test and got basically nothing out of both cylinders. I then adjusted the valves correctly and got 130 pounds out of the left cylinder and 30 out of the right which is not right at all. I expect one of the valves not seating right? What should I look for if I have to take the head off again? I'm not too familiar with the dohc torsion bar type engine so don't really know what to look for. I expect the compression to go up in the left cylinder since there isn't any oil in the crankcase but only oil to lubricate the cylinders and the rings still need to seat. I would really apreciate the help and sorry for the long post!
