hi at that altude the bike is libel to run rich as the air get tinner and colder make sure you air filter is clean

Let us know how it does. NASSIR 2 is in Colorado this year and I am planning on taking some of the same roads you will be on.

heck, my 1000 went over worlf creek pass with a sidecar attached.... just be aware that carbed bikes are a lot slower at acceleration at altitude

You bike should run okay, I've ridden over 11,000 feet with my 1500 and it ran fine though the power is down because of the thinner air providing less oxygen and the carbs being over rich. I get a bit of black smoke at high altitude when I go to full throttle, not a lot but you can see some. It never fouled a plug. Just remember that over 7500ASL you only have about 75% of your rated horsepower available and the higher you go the less you have. High altitude is where EFI really pays off. Wish I had it on my 1500, my 1200SEI ran almost like sea level over mountain passes.

Yes, it will make it ok. At 14k feet it will run like you are pulling a trailer though. At least that is a good description of how our 1100s did atop Pikes Peak.

You'll really enjoy the trip. I used to go up there all the time back in the 70's. Careful on those curves, it's a looooooooong way down!

There are no passes over 14K in Colorado! Mosquito is the highest driveable (4WD) pass in the state at 13,185.(can't ride a Wing there though) You must mean either Mt Evans or Pikes Peak but both are drive up and return on same road neither is a pass.

Several years ago, I rode my 1979 GL1000 up Pike's Peak without a hiccup: 14,110 feet. Your 1200 should do ok. Here is a link to Colorado's paved passes: http://cyclepass.com/t_tpa_co_pav_alt.html

You might try to go to the next hottest heat range plug at altitude. This will not cure the richness but might ward off a foul and burn off some carbon at the plug.



Wish I were joinning you. Have a great trip.
