I have a 85 GL1200 that sat over the winter. I started it up and the only way I can keep it running is to keep the choke on. I removed the intake and carb assembly and removed and blew out the main and pilot jets with air. I put it back together hoping it would run right but no luck. I read on a forum one needs to remove and disassemble each carb and clean. It doesn't seem to me there would be anything else to clean that you can't access from the bowl of the carbs. Any advice????
