Here are some X7 Tips: 1. Adjusting the idle RPM: All you do is twist the throttle and find where the cord goes on the engine. When you find it, twist the throttle and you will see what motion it turns the little mechanism on the engine. There is a little screw on that mechanism that is used to adjust the idle throttle. Try not to make it too high, because the bike will want to start driving on its own. 2. The battery: The battery that comes with this bike is a low quality Chinese battery. It is not necessary for running the bike, in fact my bike didn’t even have one. It is only for the electric start. The alternator in the engine will keep the lights bright when under throttle. 3. Two-stroke Oil: This can be purchased at any store that sells lawn mower supplies, etc. Any questions, just ask! I would be happy to help!
