Lifan KPX Throttle Response / possible detonation

[Megadan]

If you are not having luck getting in contact with Venom then call back American Lifan and inform them of your issue and see if they can offer an alternative. Sometimes you have to play the game a bit to get what you need. Just try to keep your cool, don't let your emotions run away with you and just approach it like a math problem that needs to be solved.

As for metal flecks in the oil, if the engine has less than a thousand miles on it, that will be normal. Seeing as yours has just 50 ish miles on it, expect a lot more. Part of the normal break-in process. Without being able to hear the engine for myself I can't give much diagnosis, but even if the thing is going to fail, Lifan has a 2 year warranty on those bikes if I remember correctly. Use it. Don't sell it just because you are emotional.
