I don't... but Ive stunted, R6, 929rr, crf50, 400ex,raptor 660(sucked) and everything else I have ever rode. I go threw phases and right now its sports cars. Ill be getting back into the game here shortly. Owning my own business, owns my fun time...
I stunted my 929rr for two years and it never blew up... Also if you wanna control them better on any of your toys, turn your idle up to about 3 to 4k rpm...makes slipping the clutch easier and also less throttle jocking....
