Are there any negative effects from cutting the throttle stop screw too short? I cut way more than 11MM off of mine. Also, found a neat way to get a little more air in the airbox. The black cover on the right side of the airbox can be removed by drilling out two rivits. Once it is off drill several 1 inch holes in the air box. You enduro guys might not want to do this because the chance of getting more crud in the airbox but for a dual sporter like me it might help.
