    Today I saw what looked like a sensor sitting right on top of the rocker cover, loose, just flopping around.left it there went for a ride till up to temp then stopped and cable tied it up high, more in a cooler flow of air over the top of the radiator.Rode back the way I came noting the temps on the dash each way.10 Deg difference. So it seems there is an airbox sensor and this other sensor take readings from a h ot environment. Could be why these things are running lean and stalling. The dash allways has read way hotter than ambient but now is still a bit high and drops quickly 3-5 Deg from stopped to back on the move. Fuelling from low down seems more crisp, no stalls and seems to be pulling harder. I plan to fiddle with it's position to get the lowest number when on the move.

    FYI.

    If you are talking about a rectangular plastic in-line item, mine came loose too. I just cable tied it up out of the way but have no idea where the factory had it. Pretty sloppy work by the Factory on this item.

    Go to my earlier thread "Where does this go?" To see pics of what came loose on my bike.

    How many wires? If its got 3 wires I'll whip up a poor mans booster plug but will take it a step further by making it user adjustable.

    Ok, you all have seen it , so it's a loop of wires hanging down from the main wiring loom just on top of the rocker cover, with a plug cover to the left of the motor, don't know what it does leading to a dead ended bunch of wires in a plug looking set up with a rubber boot sealing it with a anteater snorkel to the dead end filled with silicone. I can only think they put it there to pass emisions testing. hotter air has less oxygen so the ecu gives less fuel for less emissions. Sorry, look from the right and there she be. I like the fiddle , hope this helps, definite sharpness increase IMO.
