Sled burned down on one side did the fix kit got it all shimmed up went for a slow ride one plug is grey other is cardboard brown with a little white how should the plugs look on this sled bought the sled used never got to ride it to take a look at the plugs for myself. Also wondering does this machine jet for altitude or do I need a flash for 3100 feet is it normal for injectors to go bad or ecu, can the dealer put a scan tool to check injectors and other problems right now I am a fan of the old gen ii that I have glad I kept it or I wouldnt have nothing to ride
