Sorry about neglecting details. 2013 DL650 V-Strom. Bike starts, idles, operates just fine. Downhill and back off throttle for engine braking and it kicks an FI code. Code C65 = "idle speed out of range". But, we're doing 4K rpm in 5th gear. What idle? Forum recommendations for clutch switch but that device checks out OK. Forum recommendations for 'gear position sensor'. Changed with no improvement except lightening the wallet. Seems to me it is a high vacuum condition. Easily repeatable. CPU doesn't store codes, so it goes away as soon as you switch off. Can go hours down the freeway without triggering. Downhill with chopped throttle hits the trigger once again. Forum people and dealer are stumped. Hoping to find someone with experience before these riders venture into Central America.
