Along with what 2Many said, with the race porting, and the ATV8 pipe, there is instant throttle throughout the powerband. No dead spots at all. I've had a few Polaris engineers ride it, and they just came back with big smiles. [img]i/expressions/face-icon-small-happy.gif[/img]

I run the 15.5:1 dome, HPD race port/ATV8 pipe. No starter, milled flywheel, slip-on K&N, retarded timing, reverse removed, 39PWK, girdled cylinder, HPD reinforced block, 100LL aviation fuel mixed at 40:1 Polaris plain blue 2-stroke oil. Starts (pull start) on the first pull all summer long. No cooling fan, Redline Water Wetter. There's more, but you'd get bored. [img]i/expressions/face-icon-small-happy.gif[/img]
