    I ride a Bobber Twenty and put most of my miles on while driving freeway to and from work. While cruising or maintaining speed I feel this hesitation, almost like a vapor lock or running on fumes and about to be stranded without gas, or maybe running to lean. If I get on the throttle, the bike will immediately respond and the hesitation goes a way. Has anyone else experienced this or know what I am talking about. The service tech at my dealership gave me cute little "this guy is nuts" smile and then told me the bike is in great shape and is fuel injected so can't run lean.

    Hasn't been an issue, just an oddity. Thanks for any input.

    I have a Bobber 20 and haven’t noticed anything like that, so far.

    Excessive play in the rear sprocket damper?

    And I worry about your technician because fuel injected bikes CAN run lean,........

    That was my thought as well, but funds are tight at the moment and that mod will have to wait.

    I am not exactly sure of the guys role at the dealership, but that comment definitely caught my attention. You know how it is, you rarely actually get to talk to they guy working on your machine. The other thing he had said was something to the effect of "break in period is going well. All things check out. It is still a new bike." (500 mile service).

    IMHO it might be a good idea for you to find another tech. The one that gave you the line I highlighted has no clue.
    Now, as to your issue things I would check would be the fuel filter, a possible intake leak and then the map. Is you bike TBW? That could also cause your problem with a failing sensor.

    That TBW?,.......Noticed that hesitation when I started riding my first Scout but I guess you subconsciously make adjustments for it because after a while riding you don't notice it any more,......Been my experience anyway,..........

    I do not have a Scout, but on my Chieftain I experienced what you described in the mid-range and it would get worse when temperatures dropped and the air was more dense causing a slight lean-out. To compensate for this, or diagnose it, I went to a gas station that sold racing gasoline and mixed in a gallon of it in 5 gallons of fuel. The hesitation in mine was noticeably less due to the richer fuel mixture. The dealer did a re-flash for the fuel calibration and no more problems. Be careful how much racing fuel you try, and start with a small amount first. Good luck! Larry

    Understatement of the year .. Add air without tuning it for extra fuel can run lean as hell , enough to blow a piston ..

    @Jager

    I faintly recall the original Scouts (well some of them) having what was described as a surge.

    I once saw a good video on it, but this does not sound exactly like your issue.

    I think the fix was a ECU flash or remap..

    Have you presented this to your dealer as a warranty issue?
    Just maybe they would flash the machine for you.

    Maybe pulling the battery terminals would help with a reset?

    Sorry, I am not much of a technician here, but just a thought.

    You are correct 4T and it was fixed under warranty after a lot of screamimg from owners, me included,.......the bike would rev up at 1600 revs and if you slowing down for a stop or the like it was simply dangerous,.....but a remap fixed it. I do still have a little blip on my second First Run Scout but its not enough to worry about,.....So sorry @Jager ,....like 4T I have little to offer other than try a different shop and have their tech take it for a ride,.....

    Thank you for the advice guys. Sounds like I need to take it in for a flash.
