Thanks great advice I've been running its through it paces. only 1 hour on it so wanna make sure I break it in right!I say you can give it full throttle, just don't hold it wide open past about 5000 RPM - when you hit 5000 RPM shut the throttle completely - I tell people to 'pasture ride' it for the first tank of fuel - you want to accelerate and decelerate - heat and cool - no high RPM and no extended idling - heating and cooling cycles are as important as run time
