Went for a long ride Monday with my usual crew. They tell me the 1200 is puffing blue smoke out of the exhaust when it decelerates. OK 1) crankcase ventilation malfunctioning? 2) valve seals, valve guides. 3) bad rings? I suppose I need to get to the heads and do a pressure test. I'm gonna need a proper adapter for my pressure guage. I'm notrying even sure if there is a pcv or pair valve to test, well there has to be. Ideas suggestions?
