O.K. I just started riding this bike and the other night I was doing first gear wheelies with no problem. I would just get it to 5500 chop the throttle and it would come right up. Yesterday I rode home from work and then went out to a parking lot and could not get the bike to wheelie. It was real hot out, like 90 and the water temp read 210 so Im wondering if it is harder to get the bike to wheelie without could air? I tried taking it to 7000-7500 and still no wheelie.
