Based on the reviews not only does king motor bikes and gasbike sell low quality parts with low quality service, they ship out the wrong parts, package them terrible so they get damaged during shipping and they also steal your money by refunding you only 50% of what you actually paid. This company is a Joke. Their warranty and return policy says their restocking fee is 20%-30% which I had a hard time accepting but I get it. I returned my package because it was damaged during shipping not because I did not want it. I then read the reviews of king motor bikes and gasbike.net which are the same company btw and 90% of them are terrible so I opted out of them sending me a new one and requested loa refund. I had a really bad feeling about this. They gave me an option to recieve store credit of the full amount but that would have forced me so business with them again in the future and that's what I wanted to avoid. engine I purchased was 109 plus tax is 119.36. My total refund was a whopping 60.83. That's including tax. Your better off ordering from alibaba.com. Be extremely careful ordering from these companies!
