It was in for service on this ongoing problem I have. The bike backfires, dies, and won't restart for hours or now just dies and won't start again. They rode the bike trying to replicate the problem but couldn't. The pipes were perfect when it went in, but they blued bad after the 50 miles or so they put on them. They were doing what I asked them to do, which was ride the bike, so no problems there. I'm just wondering that if the blued pipes might point to the cause of my on-going problems could be the carbs?
