Wanted to ask if anyone had a jetting chart with all the info including ambient temps, altitudes and jets used according to this. I have an 01' CR250 , Mikuni TMX 11A carb. 38mm . I have the book but it's a clymer manual and doesn't have a chart like the Honda service manual , it only tells what it leaves the factory with. PILOT 35 MAIN 420 with a needle size of 6BEHI-73 . I had to sacrifice my good carb and rejet for my sons CR125 ( running awesome now ) and i got stuck with the TMX . I tried it on the stand jetted how it is with fair bottom power 30 pilot No mid power 65 needle and lean popping ( cutting out, stumbling ) 3/4 throttle and up 400 main jet. Thinking i'm rich in the middle and lean on top ? Anyway off to order more brass . Thanks guys.
