My 3 Top Tips for new owners. Number 1 tip, only run 10 w40 non synthetic motorcycle oil until fully broken in. Number 2, remove rear wheel and clean 6 sprocket to hub bolts, re assemble with liquid "blue" thread locker, allow to cure 24 hours. Number 3, always take bike out of gear when finished riding, the bike has no neutral safety switch, it will start in gear and take off. Alwyas make sure it is in neutral before starting.
