Fuel kills the plug, how you can lean it out I don't know. How do I know this, I rode around Tasmania a few years ago on an Enfield, had to keep buying plugs in a sixpack, nobody had any idea what was causing it, got back home and dropped the needle one notch and solved the problem. Motor ran fine through all the rev range and then for no reason it would just stop and you could not reuse the old plug. How is the aircleaner,if it is a bit clogged it could be causing it to run rich
