Hi! Brand new to Busa motors. I'm a motorcycle engine tractor puller and I recently bought a GenII busa powered tractor. I at some point want to add an air shifter and I've always heard that you had to back cut the transmission when adding an air shifter. I've read several posts where others have put air shifters on their bikes but I never read any mention of doing anything to the transmission. Will I have problems later down the road if I do this and don't properly address the transmission?
