I mainly run Byrons, but I will be trying Tornado Fuel as I have heard good things about it. Someone said possibly Byrons coming out with an even better fuel?
I been running 30% mainly until I was told at my LHS they didn't have any left. Had to step down to 20% and still using the stock OS Turbo P8 plug with flawless performance. With the new clutch setup there surely was nothing to complain about. Just need to pony up for something faster though.
