just wondering, how much of the exhaust port can you grind out with still having the right amount of back pressurel to run properly?

yeah, but now i have a yamaha jog that i just bought so, i presently don't need the elite, which allows me to work on it.

If you can afford a 70cc polini evolution bore kit, it helps but nothing beats a honda!
