After riding the CB puppy for awhile, I just couldn't live with the cloud of burnt oil smoke that wafted by now and then after coming to a stop. My guess is the bike was never properly broken in. Compression was below 100 psi, plus the head o-rings were leaking as is typical- ugly ugly. Here is a quick ride through the process I took to change the rings...
While you are at it, throw those green o-rings that come with the Althea gasket set from Italy into the valve guide inserts. Still getting some valve leakage and oil smoke on hard compression braking.
Good news is that after the first gas refill I went from 35ish to 49mpg. Niice
