I am in the process of studding my 91 kdx for ice. I need some rough estimates for jetting for 10-20 degree weather so I have a starting point for figuring out proper jetting. Elevation is about 7-800 feet. The bike has FMF pipe, and Boyeson Reeds. I would like to have it run a bit on the rich side just to play it safe if the temperature drops during riding. Any help is greatly appreciated! Thank you

FAT! I'd say a 158 - 160 main and a 50 - 52 pilot.

Cool, thanks a lot. I just wanted a starting point to go off of so I wasn't just guessing. This helps a lot.
