Altitude compensation device
Hi All,
A post earlier this week referred to an altitude compensation device for carburettor fuelled XT600. Is it possible to fit these to XT600 without replacing their carburettors? If so, does anyone have a part number or know which models and countries used them. Are they still available / expensive?
Thanks
Mark

Hi mark
The altitude compensating carburetor is different in the fact it has two separate air bleed circuits.
It will add bleed air to the second bleed circuit at higher altitudes and lean mixture.
It is a not a variable circuit but a step on -off type.
I would suspect they are very rare, you would need the carburetor and barometeric pressure sensor to make work automatically.
What altitudes are you operating at?
I have operated from sea level to near 10,000 ft but am running rich above say 7,000 ft and if I operated up there long an adjustment would be in order.
But for a cross country trip its easily manageable by raising idle fairly high above 7,000 ft.

carb is different
No, not possible. The carbs suitable for the compensation device is different; it has two hose connections extra for connection of the device.
You can cheaply pickup such a carb from ebay and just swap jest and needles though.

Why would they need rejetting?
Thanks again

yesyes
I suspect these 3AJ's have been sold in Switzerland, Germany and Holland, if not also in the UK.
It might be that the 3AJ carbs don't fit to your airbox on one side and to the cilinder head on the other side. To check for the cilinder head, check the carb boots section at kedo.com - if the boots are the same for your bike and the 3AJ, you are good (3AJ = xt600z '88 - '91 or something). On the airbox side, you'll have to modding to do.
Re rejetting; basically all the carbs on XT's / Tenere's from '86 till the last XT are the same. Your bike has such a carb with jets and needles suited to your bike. If you swap the carbs why not have your original jets and needles so you know it runs well?
