so i get the basic jetting. but i have a 2000 cr 125 with a fmf fatty pipe. i bought it with the top end blown. rebuilt it. not sure if it was jetted for the pipe before(pipe was new). we have ran 2 tanks of fuel through it. but it smokes all the time, like when its cold they smoke but as they warm up they tend to clean up.so where should i start for smokeing? needle jet? main? it seems to run ok. have been babing it for break in. but no bogging just smokes like a trucker. mix 32:1
