Pretty new to all this but I picked up a buddies old c50 to try and get it running. Probably been sitting a year or two. I changed the oil, new gas (tank seemed pretty clean), new battery. It wasn't starting and I thought it was a fuel issue so I took out the pump and cleaned the fuel filter and made sure the pump was working. Started easier after that but still wouldn't idle unless I was giving it gas. So I had the injectors cleaned and its still not idling! The FI light is on when the battery is on but turns off when I start the bike. Any help is appreciated!!!!
