The newer bikes come with the heavier fly wheel already. Not sure I would want to change the jetting if the bike is running good. A throttle cam would give you a little more precise control 1/4 to 1/2 throttle. Good idea. Having the suspension tuned/re-valved is a must gives the bike a lot sweeter ride.
I found fitting a larger back sprocket on gives the bike more control but some might say it makes it to snappy. But I sure like my. It's like a trials bike with a seat and a larger fuel tank.
