Last fall the wife found her dream bike, a 2012 FLSTN with a TC103 engine. My question is during start-up she gets an engine "drag". My FLSTC has a TC88 and starts right up every time. they both have stage one kits. When we bought it and I asked this question at the dealership the salesman told me that it probably had the air filter and pipes installed but the PO probably never had a chip installed? what does that mean or did I misunderstand? Unfortunately wifey had blinders on for the bike and I let it go. The bike does start and runs great but is the "drag" normal? what was the salesman telling me? These are the first HD's I've ever owned with EFI and if there's something more I need to do any insight or suggestions would be greatly appreciated.
