I did. what happen was about a year ago I went to start the bike and it back-fired and then would not start. I took it to the place where I bought it since it was only a month old and then said that the sparkplugs were fouled. They replaced them and it has ran fine ever since. When I pulled the plugs to check them while I was installing the exhaust and jet kit I checked the gap and both were in specs. One was just a little lean, maybe even closer to perfect but the left side was running rich. Not enough that I would really be concerned with. It was just a little on the black side.
