30 degree temperature drop
 

I have my bike jetted perfectly for 70 degrees F (21C). Going to ride same elevation but 35 F (2C). I won?t really have time to try a bunch of settings so looking for a good ball park change... up one size main, lower clip one, etc.
what do you suggest? Just going on a casual ride not a race so just looking for an easy change without a bunch of tests that will keep me from running lean.

If it were me I would throw the next size up main and pilot and tweak the air screw to suit. That is very similar to my range of temps which I get away with the above changes.

If it feels lean you can also raise the needle one clip.

We ride studded tires all winter here with just a air screw adjustment. But we are just doing single track. If we were ice racing at wfo we would go with a big main.
