Just curious, since I just got my first xi, is anyone nunning a slightly larger than 1% difference and have you experienced any trouble???
Well, I know that 6 revolutions per mile difference is .8%......which is getting real close to the edge. I kept mine at 3 revolutions per mile difference because I always see the XI's at the dealership that way. I'm think that 7 revs per mile would be cutting it close but it should still work.
