I got a new XR650R I will be picking up shortly from Kansas. I need to rejet however for Colorado Springs. Anyone have any jetting ideas for around 6,000 ft? I have checked the various websites for ideas but I was hoping to find someone at this altitude to give me some specifics. (will uncork of course)

Check out for some help in this area. If you join the yahoo XR650R group (http://autos.groups....XR650R/messages), look up "pjcarlson" as he's from CO and can give you some tips.

Just got back from Lake City, CO (8,600+ ft)...have been up there with a BRP twice, and have used the following jetting:
162 Main
65s Slow
The bike runs great with these jets...even up to 13,000 feet. BTW, I run a 175-180 Main, with a 68 Slow, in Phoenix.

My dealer here in the Denver area told me that they generally leave the stock jetting in place as it works very well at our altitude. My bike seems to run fine with it, but I have no basis for comparison.
