Was wondering Simon if you ever got the hick-up worked out. My 2018 Adventure Sport has done this from the very beginning and the dealer has logged it into my records but have not located it yet. I can watch the tach drop about 2 to 300 rpm's when it happens. It only occurs in 2 situations, at low speed when I go to accelerate, like in a intersection and when it's cold like in the mornings first start up. This has never happened while I'm driving at speeds and accelerating. Any information would be helpful.

My experience exactly. My dealer that sold it to me also owned an AT and said it is normal, but I've always questioned it. I don't worry since it goes away after a short idle, but I've never seen it on another fuel injected vehicle before.

Hey Tequila, I read in one of the posts that changing from premium fuel to regular might help the problem. Reason given was that Honda built the bike to run on 86 or higher octane and using premium messes with the computer that's programed to the quicker combustion that regular provides. The AT has a compression rate of 10 to 1 which to me says high octane fuel but the manual calls for 86 or higher. Others have switched and not only did the missing stop but their mpg increased signifyingly. So, I just topped my tank off at 1790 miles and will run regular through it and listen for pre-ignition (pings) and see what happens.

Hey Delta. That was my conclusion as well. I was surprised as it is Honda and it is a big engine, but the manual says what the manual says.

Quick update, topped off the half filled tank with regular instead of premium and getting ready to fill the tank again. Seems that the bike is running better and hasn't missed once with the 50/50 mix. I'll be filling it again with regular. Not riding much due to the weather but I'll update again when I get more miles in.
