    08 xb12 run switch, wait for fuel pump to shut the hell up, then hold start its makes a starting sound hesitates then fires up. Starter? Low battery? Spark plugs? Possibly just a tune up needed I'm @ almost 10k an I bought it 50miles ago. HD is 96$ to even look at it. You geniuses are free, with minimal description.thx

    Mine does that all the time on first cold start up of the day, I thought it was normal.

    I've got a 2010 XB12Ss with 16,000 kms.

    Same behavior here. Bought a new Scorpion AGM battery and get the same results, so now I have a spare. My ground and + cable are good.

    Assuming your battery and cables have a good connection, on this forum I have read that an improperly adjusted clutch could worsen the situation (ie, lightly dragging clutch). I also read a suggestion that switching to Iridium plugs would make it better.

    I would just like to find a good AGM battery with higher CCA. That should take care of it.

    Mine has always had a slight pause before starting. I've had the bike since 2007. I have now 37,000 miles on it.
    Start it up and ride.

    In my case, it was start it up and have the alarm go off in 10 seconds because it saw a voltage removal event (~50% occurrence). The alarm defaults to "enabled" when voltage is applied.

    FYI I did briefly remove the alarm to rule out overnight voltage drops as the cause of my initial hesitant start.

    That is normal...

    It's due to the cylinder being in compression cycle.
