I set my shift light up because I wanted to run my bike on the new drag strip they were going to build in Townsville, they got the race track part done before I left, in my "closed course" testing I had to gradually shift the rpm it came on lower to account for my slower than I thought reflexes, it's one thing to say I'll set it just below red line and another to actually change it in time, things are really moving quickly at 6000rpm or there abouts.
