Hopefully I can find someone that knows better than me on this one... I have an 09 Dl1000 with 20k miles which runs and drives great. It does occasionally have what feels like a miss or stumble at full throttle from 8k - 9k RPM. It’s difficult to describe other than it doesn’t pull smoothly when this phenomenon occurs, maybe 5-6 very brief surges while accelerating which I can only guess are misfires on one cylinder. It normally pulls fine and has plenty of power and pulls strong through the entire rpm range, although I don’t run it to the redline that often. I have no FI light or codes in dealer mode.
So far I have:
Replaced the TPS and adjusted to spec per the FSM.
Replaced the throttle bodies and injectors
Synchronized the throttle bodies
Synchronized the secondaries
Tested all sensors and verified in spec per service manual
Cleaned all grounds in ignition circuits.
New NGK iridium plugs
External fuel filter mod
Fuel pressure test and flow check within spec
Replaced ECU
Added ATRE
Added power commander 5 and remapped
I haven’t been able to pull the stator cover cap to check valve clearances because the cap is stuck and rounded the hex, so that’s ordered and on the way. Otherwise it’s a solid bike and never misses a beat under 8k. My OCD perfectionist side needs to figure this out though.
Thanks in advance for any help or insights. ?
