I'll stick with a stock sleeve bored and a fresh piston with a little more comp.....

Good decision. I've overbored a few single cylinder dirt bikes, and a 3mm is pretty radical. You'd be taking a lot of mass from the cylinder and that would limit coolng ability - wth the extra heat generated fom a bigger, higher compression cylinder and less metal to conduct it away, problems would unsue.
Also, don't go too big and powerful on the Savage unless you can find a really special clutch to fit the motor - mine still won't take the torque from my upgades even with uprated springs!
