Hello all!! I just recently took apart my motor, replacing piston rings, all gaskets, adjusted the timing, and adjusted the tappets. After all of this, I am still only getting 80psi from each side the same. If I add oil down the spark plug hole, they both got to around 115psi. How can this be with brand new rings?
A little history, the bike was purchased with One hundred and nineteen original miles, how clean the air boxes were and inside of engine confirms this. Only issue, the engine was frozen. I got it unfroze but figured I damaged the piston rings in the process as the compression was 80 on right and 70 on left. After everything was cleaned and new piston rings were installed as well as gaskets and fresh oil, compression is now 80 on either side. This is way low. Im not sure where to go from here or what else I may check. I am at the point were I want to just buy a good compression motor for the bike but good luck with that!
Thank you for your help, any comments are helpful!
