Any of you 9r B owners removed the emissions from there ride? Do you need to rejet after?? What carb settings you use after this mod? Got 200 main jets in as uk standard at the moment and shimed the needle up .5mm which helps but still a slight stutter between 8500-9500 rpm..Just looking at what setting you guys are using regarding float height/jets/mixture settings ect. Bike has a full 4-2-1 micron race system on it also.
