Will Colorado700r own me a case of beer??? Date set

[Sandeater]

I am tuned at 5,200 ft and ride at 8,500.  It runs like it should, just has less power obviously because of less air.  I got spoiled at Sand Mtn mine runs really good there compared to where I usually ride    I couldn't imagine riding above 12,000ft.  My car has a really hard time above that altitude let alone a single cylinder motor.

when i used to live in colorado springs and drove back to nj i had to have the pcm reflashed on my s10 b/c it was runnin way too lean it was programmed for the low oxgen thin air of the high elevation, and wasn't gettin enough fuel at sea level to deal with the denser air......i'm bettin on runs like crap way too rich

  My rappy still runs awesome from 11k in CO to 1K in WI. Plug chops confirm.  Try that with a carb without re-jetting

I know it will be fine since I and other people change and ride at different altitudes all the time and ours run just fine without doing a thing to them.  I don't think you can compare a fuel injected vehicle with a power control module and O2 sensor to a single cylinder fuel injected motor with a fuel control box.  If yours runs like crap it will be because you are used to being at sea level and the machine actually have true power down there 

Dirt riding sucks anyways, ride sand  :grin_nod: :grin_nod:

Then can you explain the poping and rich stumbles?

I think it was the Doebech Shawn    If I remeber right it only allows a max of a +/- of 8% at any throttle postion

Preddy, you might be buying some beer buddy.  I ride the same areas in Colorado and Wyoming as most guys here and get up to around 10-12,000 and have ridden close to sea level with no problems at all.  I also got away with running 91 fuel in Kansas with my 12.5:1 piston with no problems.  I think you get up here and just get really dissapointed, it sucks when you are used to killer performance and come ride above 10,000 feet where your motor makes 30% less power.  That takes a 70 horse bike down to 50 quick.  I do know I like to ride at the low elevations from time to time, makes your bike feel like a complete badass for awhile!

I know about power loss in the mountains. Gas motors loose about 3% for every 1000' you go up.

My bike ran perfect here and supddered and poped like crazy!

So just to update this thread for future readers....


Preddy (Shawn's) bike ran quite well at Walden Colorado.   


However, he was not running it at the extreme altitude (14K ft) that had previously either.  I believe the current consensiss is that the Raptor does infact adjust for altitude, however may not be able to adjust to extreme diffrences.

I'll qualify our results, remember niether of us changed our PC3 maps for the alt.

Preddy's results:

Omaha, NE (Home) ~980ft to Walden CO. ~8416 ft.  His Raptor adjusted for a ~7,436 ft altitude change 


Colorado700R (Aaron) Results from previous trips:

Colorado Springs, CO (Home) ~6100ft to Tarryall, CO ( riding area trail head) ~8,865ft to Wausau, WI (Parents' house) ~1195 ft.


Also, the trails I hit around Beuno Vista, Colorado are 9,400 ft to 11,800ft.
