Just wondered how many size do you usually have to go up?
temperature range winter: 30
summer temp: up to 100
Just need a guideline to get started and most importantly what is the threshold where you need to change it?
I'd like to get a good idea before hand cuz I'm not too keen on opening the carb when I'm on the trail.

My current temp is 35-50, jetting is (RB moded)
CEK needle, 2nd clip from top
pilot: 45
main: 152
I know I have a slight bog down low and the air screw doesn't seem to do much but it's ok at full throttle.
So what says you? Am I really completly off Image
Thx a brazillion :prayer:

I would try your needle on #3 to try to get rid of your low down bog.
Then fatten the main to 155 and do a plug chop.
You should be pretty close with the 45 pilot IMHO
