Lightened Flywheel
I have a 2013 GTR 35 with heads, cam, and exhaust. I'll be installing a Mikuni next week and upgrading the coils also. My question though is it worth it to have the flywheel lightened and balance while I'm at. What's the pros and cons to having this done?

Re: Lightened Flywheel
Balanced, maybe, to reduce vibration, but it needs to be the whole rotating assembly or you might not accomplish anything meaningful. Lightened, I wouldn't. The weight of all that crap hanging off the back needs to have a balance on the front of the engine, and the fact that the rotating mass of the flywheel helps when you slam the prop in the mud to dig, etc, means I'd leave it as is.

Re: Lightened Flywheel
You already have a lighter version. The older 07-08' were WAY heavier.... It is possible to static balance the engine, BUT the firing order is imbalanced so it will always have a vibration to it...

Re: Lightened Flywheel
Just as the others have stated. The inertia of the rotating mass helps when your putting around. That extra weight helps the engine. Too light and you won't have enought rotating mass to keep it running. Too heavy, and its a load to get going. Those billet flywheels work. And they allow the engine to spin up very quick, thus is why you see them in cart racing, lawnmower racing, etc. They need to have maximun acceleration out of curves and the billet flywheel allows for this. In this application, just doesn't seem practical. I looked extensively in this when doing the stage 2 kawasaki, nut opted not to for the mentioned reasons.
