Hey guys, I am going out of town this weekend to ride. However, I will be going from 100' to almost 800' sea level. Do you think that I might need to change my jetting inorder to ride at this level? Thanks

Shouldn't have to change the jetting unless you go over 3000' or so above SL. Have a good trip.

 

You'll be fine. I go from my jetting set ideally for 1700' at home to over 13,000' on some rides in Colorado. The CV carb on our KLX has a wider latitude of fuel delivery at different altitudes.

 

Thanks Amigos!

 

riding from san francisco to san diego.....i went from sea level to 6,000+ feet of elevation changes on the i5....i didn't do any jetting adjustments....bike ran fine...

 

In Death Valley I have had my bike from -200 to near 8000' above at Steele pass. No carb adjustments. I suppose one could make some adjustments if you were relocating to a significantly different elevation for ultimate performance. Too many people sweat the details when they should be riding. Have fun!

 

I'll add one caveat to the altitude deal, and it's a small one. The idle changes the most in the extreme cases like I encounter in Colorado. You can address it by just reaching down and turning it up a tiny bit. The best way is to have a Kouba fuel mixture idle screw to replace that inaccessible OEM unit. When you get to Colorado and are maintaining a higher elevation on a more regular basis, you can turn the screw in a bit to lean the mixture at idle. With this and the idle adjust ****, you can take care of just about anything.

Also people not used to going to high altitude places like CO are under the impression that you're always at those extreme 10,000+ foot elevations. In reality you're only at the very highest places for very short durations. So if you try to jet for those extremes, you'll get lower than normal performance for most of your riding. So unless you're running overly rich settings at your home area, just about anyone should be fine for nearly anything they'll encounter.

The OP's 700-800 foot differential will be totally unnoticeable. Even in CO I don't really notice any serious effect until I'm cresting something like Imogene Pass outside of Telluride and Ouray at over 13,000'. That last 200 feet or so of climbing does cause some chugging but nothing that hinders the ride.
