Hi, I own a Kymco Superdink(Downtown) 300i 2015. It had a problem with turning on the engine, it failed me while driving. When I tried to turn back on the bike it would not work, I had the turning sound though. After, replaced the fuel pump(JMP). When I started the bike with the new fuel pump, it would stay in 2000rpm in idle and not having power to move, giving me an error saying that there is not the correct percentage of air and fuel in the cilinder. I tried hard ressetting, the version in the manual and what I could find online, I tried to see if any of the airways in the intake are clogged, I tried to see if the injector pulverises enough fuel and it seemed ok by the eye. I was thinking maybe is the pump, because it could be for 125cc, but it seems is the same pump for 300cc.
I have no ther idea, apart from maybe buy another pump to test it. The bad thing is that I could not find the original part, the Japanese one, only tge aftermarket one. If there is anyone with any idea, they are welcome to reply to this thread.
Many thanks,
Para
