I've got a 2011 assault 120 with a Midwest mini performance kit(clutch, spring, gears, chain, power intake, jet adjust). If I were to pull the govenor gear, would it be wise to keep the stock valve springs on? Will they wear over time without the Govenor gear?

That will depend mostly on how you gear it and how your child drives it, higher RPMS will be harder on springs. The good news is there pretty cheap and easy to change
There are some things people don't think about much that help springs live longer.
One, good oil, oil is what cools them. A good racing, light weight oil like Amsoil 4T will flow up there and cool them much better then the automotive type oils.
Two, when your sled is stored or sitting for a period of time, even between trips, pull the rope until you "feel" that point where it turns over with little resistance. This is the point when you are not opening either valve. When you engine just stops on its own, often one or both of the springs are being compressed by the cam at that point. That spring will then remain compressed at that point for the amount of time it sits, not good for the spring life
