If a bike is jetted for sea level.....would you not lean out the jetting for higher elevation?   Higher elevation=less air?  It was stated    "if your current idle jet is a 35 then you might try a 45".  I haven't worked with a Dellorto  much.  I have a 17 Contact 250.  It was a little lean on the pilot.  Went up 2 sizes for winter and 1 size up for summer.  I think the bigger the number , the bigger the jet...Right?

 It has to do with atmospheric pressure AND the bikes come from the factory usually too lean on purpose for emission standards.

I found that out on my bike.  It runs great now.   But, the person from Colorado purchased a bike jetted for sea level. He needs jetting for his elevation. It was suggested he go to bigger jetting?  Is this correct is what I am wondering.

 If you looked at my post, he needs a larger pilot and slightly leaner than stock on the main. Remember we are talking a 200, which was not a full 200cc.

If you looked at my post, I was not referring to your post. The quote is from  Section Swept post.  He stated that it is recommended to go up in main jet sizes 15 %  to start.    I was asking if this is correct.   My jetting experience has been to not go richer,  but leaner, because of less air density at higher elevation.  Is Section Swept correct?  I did not see his current jetting.
