I'm taking a 05 Scrambler to Colorado and riding at 7-9k ft. Does anyone have an experience jetting at this altitude? Will the bike run with factory jetting? I'd appreciate if someone had experience or could direct to me to where to find this information.

 

We have a 99 Scrambler we run usualy from 7500 to 10'600 and run a 142.5 main also have a K&N filter and it runs great actualy its a tad bit on the rich side could prob go to a 140 but it never has a prob
