2013 drz400sm JD jetting kit, need help

[Jcmance]

Hello, I have a 2013 drz400sm with a MRD z-pro full exhaust system and a JD jet kit with the extended fuel screw. Could anyone tell me what settings I should use for jetting it? I live in Leavenworth Kansas which has an elevation of 840ft meaning I should use the blue needle. But, in Kansas the weather in summer is bipolar and can go from hot (above 85°F) one day, to cool (below 75°F) the other; and according to the paper I got with the JD jet kit, it recommends that if your tempatures are over 75°F you should use the red needle. So im not sure which one I should use and I'm not sure what settings I should use with regards to the main jet, pilot jet, etc. The bike is all stock minus the MRD z-pro exhaust. I'm new to jetting so if anyone could help me out, it would be greatly appreciated.

I would use the blue needle, I'm sorry for a reply so late, I'm sure you've already made your decision but it will make it run just a tad bit richer than it would if you used the stock needle, either one will be just fine and will depend on your mixture screw to fine tune it.

Well you've probably already jetted your carb by now, but I would go with the needle that best fits your elevation so that you aren't running to rich or lean, whichever.  Also don't forget to 3x3 your airbox.
