I didTWO Mikunis on my Banshee. Take the carb completely apart and clean the hell out of it with carb cleaner. Chuck up a 6" sisal wheel and load it up with emory compound. Now grind the hell outta the thing and slowly turn the 6" sisal wheel into a 2" sisal wheel. Repeat the process with a tight spiral and tripoli. I didn't finish up with white on a loose wheel 'cuz it grabbed too much.

Some serious pressure and buffer "grunt" is required. You might wanna eat a bowl or two of Wheaties before you start. heheh
