I use my bike for mostly daily riding but go to the drag strip probably every other week during the summer. I haven't done anything major to my bike just a few small things to make it faster for the strip. I've decided to stretch it since I geared it and now the wheel won't stay down. My question is that my buddy has a 4" over swingarm, would that be enough to keep me down or would that even make a difference? Also, how much would that affect drivability?
