if you don't want to deal with a Gaokin you can get rotax version, I dont know if you can get it new from Rotax as it probably OEM buyers only like can am, you can get used or refurb/rebuilt engines though I found on ebay, Kevin says the castings and quality look great for the Gaokin engine, my engine arrives any day now for my initial testing and development. Im on west coast right next to Oakland seaport. you need to add a lot of importing costs over any quote you get from any exporter. been there done that. engine proven in the UTV/ATV/snowmobile industry but now has to be proven for aircraft industry. as mentioned by other member Hisun UTV company out of Texas uses this engine in its UTVS for years now. Hisun WILL NOT sell engines outright. I will make sure Kevin gets the credit for this discovery , lets hope its a success story, we could use one! engine without radiator and coolant and oil is 92 pounds, redrive around 11 pounds, add weight for radiator, exhaust and liquids to get a ballpark final weight. EFI is made by Delphi, engine comes in two versions SO WATCH OUT, you want version WITHOUT CVT and gearbox/output shafts.
