Hi Kelly, In my opinion you are doing the right move with Seafoam. I use it every tank on my 85 Aspy. Your bike with 58k miles is running lean. There may be dirt in the carbs (likely if it sat with unprotected fuel in the carbs), but 1st you must do a carb balance with mixture screw adjustment. The mixture screw controls idle AND off-idle fine fuel adjustments. Adding a shim to the metering rods and up sizing the jets will also fix this lean condition, but if you haven't changed the stock exhaust there is no reason for making these changes. Take up the offer from Rockford to balance the carbs (very important) and make sure to set the mixture screw as well (procedure in repair manual). Best of luck.
