I just bought a 06 EFI M7. I was told it has a D&D pipe and can but I can't find any markings on either. The sled runs good other than a low end flutter on the fuel side. Is this common with the EFI models? Can I adjust it myself or is this a dealer issue? This is my first sled with EFI so I'm a little lost when it comes to tuning. Also, from what I can tell it is running the stock clutching combos for 6 to 9000 ft. which is where I ride. Has anybody changed the clutching for better performance or should I go with one of the kits from Black Diamond or Sled Junkys etc.?
