    Up to 1400m, Do I have to adjust XRW's carburettors?

    Hi!

    I´m going to drive up to 1000m - 1400m. How high can I drive without adjustments?

    What happen if air is too thin? Poor performance maybe? What else..

    I've been up to nearly 3000m (9,000ft plus) on my XRV without thinking about the carbs or experiencing a noticeable loss of power. I wouldn't worry about it.

    I believe you'd be well on the way to 4500/5000ft before having any trouble and even then,one bike can be fine when another will start playing up .

    edit : at these levels though temperature and humidity can also come into play (I see your in Finland)

    Geez ! another edit : I meant of course 4500/5000 metres (thats very very high ! I've only done a few hundred or so over 3000 )

    I've been up to 5000ft on my africa twin with no adjustment to the mixture needed!

    Okay thanks!

    5000ft = 1524m So probably I don't need to be worry.

    This is my first trip up to mountain, what problems thin air can cause?

    Lack of power due to an over rich mixture because there's less oxygen at altitude (sort of like riding on full choke with a warm engine).
