    Has anyone had the experience of riding from seal level up to higher elevations ? I’m talking 6…. 7…. 8,000’ elevation. I’m sure at that elevation the air fuel ratio would be so far off that riding the bike would be unbearable and probably not too good for the bike?
    Any quick tips or tricks I can use to help me on this journey ? I’m looking to ride from the SF Bay Area up to some very high sierra locations and would like to make some adjustments on my carbs with out a lot of time. I’m willing to take 2-3 hours for this, but anything more than that might make me change my mind.
    Thanks in advance for all your input

    there are charts and graphs that can show how a/f can be transtated from sealevel to any altitude, common in small planes. so maybe a 120 main would need changing to less, like 100 or so @ 14k feet.

    Should be ok. I'm at 2000m, 6500ft, and ride to the coast and back no issues with standard jetting.
