when mine was a stock motor with an old fmf exhaust on it 13/36 sprockets and 20" tires, we got it to 81mph and still had just a little bit more to go

Tire size and sprocket size is going to have a HUGE effect on your top speed, much more so than your pipe, reeds, and air filter. Those things affect how quickly you get to top speed, but it's your gearing and RPM that actually determines the speed.

But let's assume everything is basically stock, with the stock gearing and stock tire size, you're probably looking at 70mph or so.

Like I said, your pipe, filter, and reeds will get you from zero to 70mph a little quicker, but they won't get you up to 80. For that, you'd have to change your gearing.
