My mc18 has always been very smokey during start up and well all the time (at idle). Andy I was wondering if you ever got around to replacing the crank seals on your NSR and did it make a diffrence in the smoke out put. I don't really mind leaving a light in a big cloud of smoke. I have never had any gas in the gear box and have never noticed the gearbox oil level drop. I had the jetting set and have the smallest pilot jet I could find installed.
