Here's some stuff we learned about the new Arctic Cat "F"'s.
F6
MPH: 85-105
RPM: 8000
Fuel: (no premium) 87 Octane only
F8
MPH: 90-110
RPM: 7900
Fuel: (no premium) 87 Octane only
F10
MPH: 95-115
RPM: 7350
Fuel: (no premium) 87 Octane only
Frame front arm straps (up ½ inch up)
Dully runner to single (1 to 2 mph w/arm strap up ½")
Rear coupler blocks in lowest position (improves traction)
Low windshield 2-3 mph faster than mid and 5-6 mph faster than tall
Additional Idler wheels in frame 2-5 mph (based on snow conditions) saves on hifax
96 studs (minimum) is recommended to stop track spinning at low, mid and top speeds in marginal traction conditions (huge difference in acceleration)
2 gram heavier drive clutch weights may improve speed in a straight hard flat drag condition, but will generally pull down bad in deeper snow
