Several gas stations here in Indiana sell kerosene. It might be hard to confuse it with unleaded cause the hose on the kerosene is only about 2 feet long. Hope you didn't hurt anything.
On A ride \\;here in \\;Alaska from Anchorage to Talkeetna, I had a Buddy who was not looking at he pump and put a Tank full of Diesel in his Softtail. The lucky part is he noticed his mistake before he started the bike. He talked to the station person and got a can and drained the tank. He filled it up and never had a problem. Talk about Dumb and Luck.. So dont feel bad it happens
