does anyone have this kit installed?

1- i'd like to know what upgraded carb is recommended
2- what upgraded exhaust is recommended, i only see two from DC available online
3- what cam is recommended (along with any additional head work, springs, retainers, valve job)
4- heavy duty clutch springs? clutch replacement?

the goal is to gain power across the board, this is not to drag bike or dune bike, i'd like to keep it reliable and easy to start

thanks
mike
