you guys actually warm up your two strokes? cuz my buddy with a banshee is always like you have to wait to warm up your 2 stroke so that you don't crack your piston, is he right? what do you guys do, how long do you wait?
Engine parts expand as they warm up, and they are designed to run at full operating temperature. Until all the engine parts are hot, they're not at their proper operating dimensions. Before riding, I always warm my engine till it's too hot to touch. I usually change RPM during warmup with slight blips of the throttle.
Let it idle and periodically give it bursts of the throttle until the radiators are warm to the touch and you should be good to go. But if you warm it up too long you could cause overheating because theres no air moving through the rad fins to help cool the bike.

Yes, and my 4-stroke when I had it as well. As stated in some of the posts the engine parts clearances are designed for when the engine is at operating temp. To hammer it before then can cause premature wear and even cold seizures (though you don't see that much these days...)
To warm mine I usually let it idle for 3-4 minutes with a few short slight cracks at the throttle then ride in second gear for 5-10 minutes then it seems to run like a champ and usually doesnt bog!
