carb adjusment

Postby flojo » Mon Mar 24, 2014 1:07 am

HI, I have an 86 aspencade. A few years ago, we took a trip that involved crossing the Rocky Mtns. At the higher elevations, the bike lost a lot of power. We were able to get over the great divide but for a time our top speed was pretty low. We live on the west coast at Sea level and the bike runs fine there. Crossing the sierras was not a problem on the same trip, but the higher elevations of the Rockies really reduced performance. I was told that the carbs could be re-jetted to make them perform better in the higher elevations --is this something to consider? If I get them re-jetted to perform better at higher altitudes will that cause worse performance a low elevations? Just looking for opinions

thank you

I wouldn't re-jet unless you spend more than 50% of your riding at the higher elevation.
And yes it will affect sea level operation.It will run too rich.

You can always turn your choke on a little bit at higher altitudes, that will enrichen the mixture and help you get (most) of your performance back.
