1983 yamaha yz80 carb jetting

[dodgehemi]

Just wondering if anyone knows what the carb jetting chart is for a 1983 yamaha yz 80. I have a PSI pipe on it and it is set up right now for about 75 degrees f, and would like to know what to run for jets and needle settings for temps down to 0 degrees F.

Cold air is denser so youll probably have to bump up both the pilot and the main 1 or 2 sizes or maybe just the pilot or maybe just move the needle postion down a notch if it bogs some. You're almost going to have to experiment a little with it to get it running spot on.
