2004 kingpin backfire
My 2004 kingpin is backfiring a lot, the check engine light was on and a friend told me about the electric connection on the front of the bike at the base of the frame, he said the connection could be off. So I cleaned it and bent the three prongs slightly a and re connected it. Check engine light was still on, so I disconnected the battery for a minute then reconnected the battery, light went off but still backfires. Anyone have a suggestion?
