I recently bought an 01 FLHTC with 13,000 miles. Records of service work came with it. The former owner installed Vance & Hine pipes and had the dealer install Screaming Eagle (?) box and remap. He later took in for fast idle after warm up. Dealer replaced intake gaskets. The bike still idles around 1100+ rpm when warm, 1050 cold. What do I need to do? I am use to a carb and idle around 600-700 rpm. Thanks.
