Vary your throttle and change out the break in oil at 500 miles or so. I kept it around 65 and below for the first 1000 miles. I've had no problems with my engine since new and she runs like a bat out of hell. You want to give the rings and such a chance to seat properly before pushing it hard. Change your oil at recommended intervals and keeps the valves adjusted. Your bike should last a good long time. Enjoy!
