Bobby's right the carbs need to be disassembled if one of the carbs has one piece of blockage in at the bike will not run correctly and the only way to do it right would be to tear the carbs down go to the right top of the home page and the search carb cleaning carb disassembling you'll find a thread that somebody has already done this,the only other way to do it would be to take the carbs off and take them to a local motorcycle shop and have them cleaned it's more expensive that way but the only way you're going to learn is to do it good luck Jim
