Bests & Worsts Reviews from Amazon

First and foremost: This is not a Honda or Yamaha... if you are not mechanically inclined and own some hand tools, you will probably be quickly disappointed, so move on. If you want a high quality bike that you will not have to repair, maintain and customize, go buy a new Yamaha PW50 for $1500. If you like like tinkering, customizing and enjoy a bargain, read on. Overall, this little bike is a good value. Like all inexpensive Chinese powersports products, it is for the most part solid and reliable. The frame is solid with good welds. The engine is a Honda GX35 clone, parts aplenty. The plastics and controls are cheaply made and will break at some point. Replacement parts are dirt cheap and readily available. The clutch/chain drive is the same thing as many pocket bikes and bicycle engine kits, readily available. You WILL have to tighten bolts, add lock washers and fix piddly things. Initial impressions and suggestions: 1. Immediately drain the oil that comes in it and replace it. Mine had fine metal particles from machining (They don't do a great job cleaning engine parts before assembly) I put in Mobil1 10W40 and will change it again after the first few hours of use. 2. This little bike is way too fast for a beginner. The stock twist throttle appears to be adjustable, but is poorly designed and made and does not actually adjust. Replace it with a thumb throttle (with an actual stop screw to limit speed) for about $15 here on Amazon. 3. Other reviewers had mentioned the rear sprocket loosening as an issue. I found the initial chain tension extremely tight, and not lubricated. Remove the rear axle nut and chain adjuster to get a straight shot at the socket head cap screws, remove them one at a time and add lock washers (and a drop of loctite) to each bolt to prevent this issue. Lubricate the main drive chain with some real chain lube. 4. The gear reduction chaincase (from the clutch to the rear drive chain) has very poor lubrication from the factory (looks like very small amount of clear silicone grease). Remove the four small and two larger bolts from the cover and put a healthy amount of real chain/bearing grease on the internal chain and sprockets. 5. Check the bike over after each use until you are comfortable that the little issues are worked out. I will update this review as we put more hours on it.
