My bike seems to runs flawless. I run in temperatures from about 60 to 90 degree at elevations from about 2000 to 4500ft. My main is a 168 and pilot 48 fuel screw at 2. My problem is when I pull the plug it appears to be running a hair rich. Not rich enough to be fowling but rich still the same. For fear of messing with jetting because it seems to run so good from the saddle, what is everyones thoughts on running a hotter plug to remedy this? The bike calls for a CR8E/NGK. Do they make a CR7E (slightly hotter)? And what are everyones opinion on doing this, is this this just a bad idea?
