How XT600 work in altitude?
 

We have a XT600Z Ténéré 2VG (3AJ Brazilian version...)

We're planing a trip to Chile in the summer, 2 up, maybe passing trough the "Paso del San Francisco", reaching more then 4.750m in altitude...

I'm a little afraid with carb problems in that altitudes... Someone knows how the XT600 perform in that environment?

PS: I know the humans didn't work very well... ;-)

Might be that the Brazilian version has the additional air valve that was also installed on the Swiss version (3DS). You can recognise it as follows: It looks like a cilinder with a dish on one end, two small hoses leading to the carb. On the Swiss bikes it is located just above the ignition coil, left side of the frame, in a rubber ring.

If you have this thing you will not have any problems at altitude. However, without, depending on the carb adjustments you will certainly have problems above 2500 m. Lack of power, holding in etc.

hi,
I recently traveled through northern Chile, Bolivia and Peru on an XTZ660 which has same carb set up as XT600 (Teikei combined slide/CV carb). The bike started to lose performance at about 3000m, and at 3500 was missing badly and would not accept full throttle. I lowered the needles in the carbs, down one notch on the slide carb and as far as it would go on the CV carb (2 notches). I did not change the jets. With this change the bike ran fine up to altitudes of 4700m. This is not an easy adjustment to make however as carb access is very poor to do it in place. Removing the carbs is also difficult. You should practice doing the adjustment before the trip. Note that you move the clips on the needles up to lower the needles and lean out the mixture.
