    Default 2019 250 sx

    Curious with all the talk about the new carb, does anyone run stock jetting at or near sea level? Results?

    Check AJ's specs, he's in Texas too and very knowledgeable
    His setup was confirmed by others

    I have a 19 TC and tweaked his settings but I'm slow!

    I ran the bike stock for a bit and it was much better than the 17 I had.
    I'm in FL so pretty similar to TX temp/alt/humidity

    I know this thread is a bit old but wondering if anyone has updates on 2019 settings. Raced the bike stock day after I got it. It ran decent. Did the gasket, o-ring and JD jetting kit but haven't ridden it yet. I wonder how picky jetting is on these with weather changes. Going to enduro next week and will be 30-50 deg F. Thinking I need to richen it up from baseline settings.
