Hi,
A few days ago I brought my 2006 DL650 out of winter hibernation. It’s been sitting unused for about 4 months which is the longest I’ve ever left it as normally I ride pretty much all year.
Anyhow first ride out I notice a massive drop in power at high revs. Bike feels like it’s been restricted or in limp mode. Then I see the red light on the clocks and the FI error on the LCD. Back home I read about the dealer mode and make that change on the connector. Error code is C28 (secondary throttle valve actuator) and happens after about 5 -10 minutes of riding - but the power drop is present all the time.
Further research and I’m beginning to understand most likely cause is something has seized in the throttle bodies. It’s a little out of my comfort zone but I’m probably going to attempt a repair myself. There’s quite a lot of stuff to take apart and put back together before knowing if it’s going to work, so I’m a little hesitant. Could anything else be causing this? Any quick fixes or tests I can do before the tank comes off?
Cheers
