Actually its a 12 minute tune.
dead easy.
start the bike with out touching the throttle.
let it run till the fan kicks on.
start timer.
12 minutes later its tuned.
thats your 12 minute tune, plenty of threads on it here.
my header was always red hot anyway so i don't think a few more degrees matters, the tape just keeps it off my legs. It was mostly an experiment, don't know if i would of bothered to do it again. I do like the lower temps on me old legs though.
