I have always broken in engines hard. It's all in varying the rpm's. Dont stay at any given throttle position for more than a mile or so. Use Premium fuel, and oil. Ride around some back roads for a few days. twist the throttle easy into all your takeoffs. let off easy on de-accell. Just vary it constantly. Most of the break in is waiting to see if something/anything will indeed break. Listen to the whole scooter for ticks or squeaks. I would run for 2-3 days, and change the motor oil. run for about another week, and change it again. Because you are accelerating the break in you will need to accel. the service. At your second oil change adjust the valves, and your idle mixture. The idle is set rich to keep the valves lubed during breakin, and will need to be leaned out as the engine spins easier. Under the general topic there is a link to get to a service manual for your people. That will help alot. Common sense will tell what is happening w/ the engine. The recommended break-in is a blanket to protect both parties. I have run brand new builds at full throttle, w/ no ill effects. You just have to listen... Just my opinion. Welcome to the forum.
