    70-71 is probably right top speed. You should look into getting the R&D rideplate machined for more top end speed if that is what you are looking for.
    Most people on here use the Riva EFI controller. I believe Rossnemo has some experience with the powershot. He has a nice thread that stickied on the top of the 2stroke yamaha section on efi controllers. you should read it
