    Carb adjustments for a cross country trip

    What is the forum’s experience on carb settings for a cross country trip where conditions/elevation varies?
    I have 2019 TW200 and seems to run great here in Michigan (1000 feet above sea level), basically with stock carb and settings.
    I tend to ascribe to the “ if it’s not broken don’t fix it” approach, but is that wise when on is contemplating something like the TAT?
    Can I get by without having to change things on a trip like that?

    Plenty of people are using the stock tune for that use. The only thing I'd recommend is a flex jet so that you can properly keep your idle and starts consistent. Not necessary but nice to have.

    I commute at 200ft. So for me it made sense to richen it up a touch. Otherwise I would have left it alone

    after you figure out the carb, don't forget to reinforce the sub frame, it doesn't have much of a chance of surviving on a trip like that, in it's stock forum

    If you are getting along with stock carb settings from the factory like I did for a long time, you will not need to change anything

    You will be fine with some minor idle adjustment up to 7,000 feet. Above that it will still start and run, but may bog some at WOT in fifth. Above 9,000 you will lose a lot of power and may have to stay in 1st, 2nd, or 3rd. Above 12,000 you will be forced to change the main jet to 2 or 3 sizes smaller to have enough power to climb steep hills. I go to a 118 in Colorado at 8,000 and above.

    I ride mine on the beaches of the Pacific Coast...and at 10,000 ' in the Mountain West with stock settings and have had no problem.....however I am not riding for hours at highway speeds of 55 mph...….obviously there are bikes that are more suited for a cross country trip.....I have done it with 650 and 750 road bikes on blue roads.... but....what the hell...I admire your spirit of adventure...…

    If I were you I would plan on eating in restaurants and staying in motels and traveling as light as possible to maintain the bikes very marginal highway performance .....and my very marginal body...….. including my very marginal butt....

    I ride from about 1200' to 6500' with 130 main jet. Seems ok for 200cc's.

    That’s good to know
    You have hit on the exact premise of the idea!
    Travel light,hotels,TAT so not much highway.
    Still in the dream/planning stage, but I suspect smaller and lighter might keep things in perspective...
