2012 300 JD jetting kit

Ok so I think i've got it pretty good now (@50deg. 500ft elev.)
JD jetting kit
Blue Needle 2nd clip
180
42 pilot
1.5 out on the air screw (stock was only 1 turn out & I had not checked that.)

A half turn out on the air screw from 1 to 1.5 out made all the difference took out that little stutter then hard hit of power.

So now that I have it pretty good what happens if I go from my usual conditions of 2,000ft 50-60deg. up to say 5,000ft or the temp is 80deg. coming from the 450 I never touched it no matter where I rode. What is the rule of thumb or should I not need to do anything?

As you go up in elevation the temp also drops and keeps things somewhat even. I wouldn't worry about making any changes for your first trip out. The idle and off idle resp can be adjusted easy enough on the fly by turning the AS out. The rest just take notes and you'll know for next time if you need to lift the clip or drop the main a size or two.

Oops.. Re read you said up or hotter. Worste case the bike will run a bit rich and fluffy, maybe some light burbling and extra fuel usage. Only once you ride it will you know if it requires a change or not.
