rejetting for altitude?

**wildwade** · #1 24 Sep 2003

My KLR's engine carb and exaust are completely stock. If I plan to travel through mountains, is it a good idea to have extra jets to switch to when the air thins? And if so how difficult is the job? I hear the carb's a bitch to remove. Would it be difficult to get by without rejetting? thanks a lot.

Not exactly a timely response but... I live at about 6,000 feet and routinely ride up to and above 10,000 feet. Have not had a problem with my KLR and have not touched a thing.

Likewise I agree that rejetting is not necessary unless you live or plan on traveling exclusively at high altitudes.

I took my 2003 KLR through the Andes this last year and noticed some sluggishness above 10000' (and more so in Peru at 16,000'- the worlds highest driveable pass), but knew that the rejetting process was more trouble than it was worth. Also, we traveled from 16k down to sea level in the same day and the bike was back to normal.

I think as a general rule, it's not worth the trouble.

I'd pretty much forgotten I'd posted this question, but thanks very much for your answers. I won't worry about it then. The rockies just arn't that high.

Well, I'd have to say the Rockies are pretty high. Not Himalaya high, but there are roads that take you over 12,000 feet. Again, hasn't really affected mine nor my buddy's KLRs and he lives in Chicago which is definitely pretty low.
