Also I forgot, the only problem we have had with the bike is the Jetting. Since the bike is manufactured in California they run the carbreautor very lean to pass inspections. What we used was a White brothers Carb Kit. They have all the jets, and new diaphragm pump. They run for about 100$. A cheaper alternative is to buy the Boysen Accelerator Pump Cover which reduces any bogging or throttle hesitation. They run for i think 70$. Either way both will greatly benefit the bikes performance. Other than the carb we have no trouble with the bike. Good Luck.
