    Does this engine have a large round decal on the clutch cover (right side of the engine) with a yellowjacket showing his stinger? You have bought it and it's being shipped already? A little late for the question you are asking, I have no idea about this engine but......welcome to the forum(^)

    I don't know Stingers, and there are no pics here, but I may still be able to help. Take a long hard look at the fit and finish. If you have the tools and know-how to put it back together, take it apart and check it out. You may see some things that will give you trouble later, or parts you may want to change out for something better.
    Basically, you want to get an idea if it will be worth the trouble to you. I have heard that these little 2-stroke engines can differ greatly in quality, often even ones from the same manufacturer. About all you can do is determine if yours is made well enough to run for a good while. Then, it's up to you to assemble and mount it correctly, check all nuts, bolts, fittings, carburettor set-up, proper break-in procedures, maybe a better spark plug, etc.
    The better it's adjusted and treated, the better it'll run.

    I have a stinger engine... They are pretty good quality. Good casting on the cooling fins, 415 chain and sprocket, ball bearing idler. Really, all of these engines are very similar (and probably come from the same factory). The most important thing is being able to return it for refund or replacement if there is an issue. I know for a fact that the owner of SD Stingers will answer emails pretty quickly, but don't even bother to try and call. If there is an issue, he will take care of you...

    I have one. Bought mine in 2009. I only had to replace the head gasket so far, have roughly 2800 miles on mine. Well also replaced the stock flat head screws on the motor & plate covers with allen head bolts. But if you use a good oil & tune your carb correctly with a good exhaust pipe you should have a great time with that motor. Welcome to the forum!! .shft.

    Yes, a 49cc Huasheng is a longlasting, reliable and quiet 4-stroke motor for a bicycle.

    im sure the stinger is the same or very similer to any other Chinese kit.
    and Chinese kits do last a while if you put them together right.you should be fine.
