Just picked up a 07 Deuce.Got it as it was coming out of the factory warrenty and was able to get a 3yr. extended.I want to install a Vance & Hines pipe and air cleaner and fuel pack or a Stage 1 download for the computer.Will this Mods. create a problem for me if I have a warrenty issue? Also,Stage 1 down load or Vance & Hines Fuel Pack?What do you guys recomend?
