Pipes, reeds, and head (20cc or less). You can use pump with 20cc but 100ll avgas from your local airport is best and cheapest. With avgas you can even use 19cc domes.
Traction is key!!! If you don't have good tires, and clutch,power is useless.
Two of my friends have 700's, one stock and one with pipe, K&N, and the EFI mod.
Honestly, they're no threat. With those mods, you can beat both.
A 60 shot huh?? That's funny. Hope he's wearing Kevlar underwear.
A 450 is of more concern then a 700.
Have fun.
