Back in 2008 I went from 750ft in IL up to 10,000ft in Rocky Mtn Natl Park with a stock bike. I took extra jets and played with them some, but finally settled on simply removing the airbox lid. It would bog at wot, but fine up to that. Good enough for the time I was there. Some info in this old thread before I went.

I was back there last summer with a 351 and FMF Q4. Took extra jets and a kouba screw. Bike fired right up and ran without issue. Up to the tree line on the old Rollins Pass rd . 10,000ft +/- Never changed a jet and the kouba screw is still in the bag :( I should put that in this winter while the bike is apart.

dan, I wouldn't go to Colorado or anywhere else with you. I'd be constantly terrified of seeing an upside down, out-of-control, KLX flying at me...just like that scene in your last video...LOL!:D

I live at close to sea level, maybe 300 ft, and I ride up to 3000 ft. At 3000 it does start to sputter slightly. I'm running the 132 and 40 with no airbox lid. So can anyone answer this: The higher you go the less air your bike will need or more? If I went to say 10,000 would it help if I put the lid on? Or is that going the wrong way?

EMS_0525 01-20-2011 05:12 PM

Thats the wrong way.... there is less air up there.... you need less fuel...

So if I ran with only half a tank it would be ok? LOL:p:p:p

Deej I think you run on half a tank all the time. :D LOL

But like EMS said , you need less fuel or more air at higher elevations. You need to keep the ratio of oxygen and fuel the same, and there is less oxygen in the air at higer altitudes. Removing the airbox lid once I got out west was enough to get my ratio close to where it should have been. I know you lid is off already, so you would have to go to smaller jets to correct the ratio on your bike if it was really going to be an issue. Sounds like yours is fine for the majority of your riding.
Dan @ 1/2 tank also :)

OUCH!!
And I was thinking of inviting you along to haul extra fuel around for us in that honkin tank of yours :D :D

I promise no flying KLX. I'm sure EMS could tone it down a bit, and Cjcrashesalot sounds like a safe rider just by his name. :D You could make the trip up from Tejas in a couple years. I know you can spare the time, your always gallivanting around on month long trips.


EMS that sounds like an awesome trip!! Should be fairly inexpensive too, camping in the toy hauler, and cooking your own food. . ""honestly i dont care, as long as im not at work and on a motorcycle ill follow the leader."" Agree 100% :):):)






no riders were hurt in the making of that video

Yea when im out there im not going to ride the same i do here at home. It is going to be a vacation for me, not a fast pace ride. Stopping to take lots of pics and take it all in. Ive never been there before. Plus i dont want to get hurt a couple days into a 14 day trip. Its going to be awesome. This is the year my life is changing...
