Can anyone tell me what circuit the gray wire that everyone is hinting for me to undo is in? Why is it there and what will undoing it do? I'm trying to get rid of the stutter at a constant throttle position. I've uncorked the exhaust and went one mj richer (165) stayed at Canadian stock setting pj#48 and to the 5th clip position on the needle. I rode in the foothills the other day @4000' altitude and 20c. I felt it was rich enough and was blown away as this was my first big ride on this amazing bike. Plug shows air/fuel mixture good (clean, light tan color). I'm totally happy with it except it's got that inherent trait of not holding steady rpm with steady throttle input. I found what I've been told is the gray wire in a connector under the fuel tank and under the frame just behind the rads. Can someone confirm that this is the one (its in a connector with six sockets/pins and its the only gray wire I could find). Also is this mod applicable to the 04. The tps disconnected helps a bit but doesnt eliminate the stutter. I'm going to try the acv mod too but don't think it should affect the rpm at steady throttle as it is sprung open until a large vaccuum is present.
