i have spark on both cylinders, there is gas giong through the carbs, but for some reason its only running on the right side.. Im not to sure why.. I was cruizin on a hot day last summer with my girl on back.. All the sudden I heard a loud noise, like a gun-shot... and oil was coming out the top-ends pressure release tube that connects to the air-box.. It blew off the air box and sprayed hot oil all over my left leg and hasnt ran propery since.I was told it mightbe a timing issue? Can you help.. Thank You Brock
