What do you mean by side draft or down draft?Gixxer_Six2003 said:Carbs aren't bad at all, especially if they are Mikunis. Getting the screws out is the worst part. Does the RF have side draft, or down draft carbs ? If it's down draft, the emulsion tubes may be getting "egged" out, and letting gas slip by the needle. Get you a manual, take a saturday and pull them off. Clean them throughly with carb cleaner, using the can's straw to blow out all the holes. reassemble, check float height, then put the carbs back on.
