Going higher the air is thinner, this will richen your air fuel mixture. It should not be a problem especially with a CV carb unless you are running real rich already.

Your bike will be fine. The carb will adjust itself well enough to get you through, as Cruiser says.

I was in CO with a buddy that has a 2002 Heritage. He has a carb and didn't adjust it at all.  Motor was stock with a set of V&H Long Shots. He was fine.  The only issues he had was when climbing into the higher elevations he could not keep up.  He described as the power would just flatten out and wouldn't pull anymore.  We would wait for him at the summit and then head down.  More of an inconvenience than anything. Pulling a trailer is a different story though.

That was probably due to the Longshots.

And don't be afraid to work that transmission.

Any engine will lose power at elevation. You need to change your riding style if you want to keep up. Down shift and wind 'er up a bit more. My bet your buddy rode it like he would on the flats and the engine did not have enough power to keep up running at low RPM.
I am an adult?? When did that happen, and how do I make it stop?!

All these answers are presuming that you have the original CV40, or any CV carb. is that correct?
Have you corrected the jetting now, if not, you had better, or was that the upgrades to the "carb upgrade"?

Many start rich at sea level and at elevation they go stinking rich. Sluggish.  Of course high elevations derate the power, the cv does not compensate completely.

Went out west a few years back with 6 other bikes, only one was carbed (03 lowrider)and the only time it acted any different was at the top of Beartooth pass. Just cranked a little longer before starting. No other issues   I see the pile of 8ft firewood in the back ground, I assume you have a hot water boiler. Bet that pile is going down fast this year. Below zero once again this morn.

LOL, several years ago I was doing top end on my bike and noticed that the wrist pins were a little loose, so took it to a local to have new bushing reamed. Guy did not know what he was doing and got both of them crooked, and the pistons were moving up and down at a angle. I did not realize what he had done and the bike was running fine. I had about five k on it and left for a tip to Colorado, got to New Mexico and knew something was not right, but figured that I would fix when I got home. Did the passes, bike got worse and worse climbed Pike peak in first and second gear.
I was not about going all that way and not seeing the sights even if I had ship the bike home. On the way home I was using a quart of oil every 100- 200 miles, yea I was buying it six at a a time and keeping four in the bags. No interstate, back roads at forty mph.
Got home pulled the heads and had both top rings broke, a quarter inch + gap in the rest of the rings. Needless to say the rods had to be rebuilt so pulled the motor for a bottom end rebuild as well.
What a great trip, would do it again, oh yea hit a deer last day in Colorado.

We're based in Denver and when we bought new FXRPs in the early 1990s they had the early Keihin CV cabs and we had to have the main jet on each one changed to a smaller size or they ran too rich at 5,000 ft.  We never needed to go up higher while escorting funerals in the area but did notice the later FI models needed nothing even at 11,000 ft.

I have a 2000 carbed FLSTF with the Andrews 21 that "lives" in Colorado.  I've never had any kind of issue with elevation changes going up and down the mountain passes and I would be surprised if you experienced any issues.  My house is at 7300' but the bike is jetted for 1000' and the only discernible difference is that first start on a warm day requires very little choke at 7000' and higher.  A cold start at temps below 40 degrees will require full choke and about two twists of the throttle.... Because I occasionally ride the bike to lower elevations such as Phoenix at 1000', I've never bothered with "mountain" jetting.  Bike still has plenty of power and that cam is especially suited for the mountains with it's flat torque curve.  When I ride with other people, I notice I don't have to downshift nearly as much as they do and no, I don't lug my engine either. 

As a rule of thumb, a normally aspirated, internal combustion engine will lose 3% of it's potential maximum power output for every 1000' of density altitude gain so yes, you will "feel" the loss of power but that would be true of any normally aspirated engine.

Have a great ride and I would not recommend riding in low angle light due to the elk and deer wandering about !

we haven't determined exactly when we'll be leaving yet, but we definitely are heading to the Durango area as a base camp for a few days
