Yes it's an awesome manual, super legit information, and tons more modifications you can do, I'll post more info soon. I googled the intake and found this
I'm very excited as well for tuning this bike. Now I'm trying to figure out how to construct a intake like these, if you know how or can figure something out keep me posted. It would be awesome to find one but I'm sure are very hard to find.
Another thing you can do is open up the rotary valve a couple degrees on either side, there should be a template online (or at least be able to find the exact amount to cut away) to emulate the valve from the G31M Centurion Baby Green Streak. It's a very easy exercise to really tap into some of the potential of these motors.
