Hi, I was wondering if anybody had any recomendations on jetting for a 2003 Rm/Kx100. Right now, its really cutting out at high RPMs. It has a 138 main in it right now, and the needle is in i think the 5th position. I aslo has an FMF SST pipe and Shorty silencer. any help is appreciated.

I wanna say try a 140 mian. and then if that is a little too rich, move the needle to the 3rd position. Also check your float hight. Maybe it is too low so you are not getting the proper amount of fuel needed into your bowl.

When mine did that we went to a 140 main, 3rd position and adjust the float hight a lil, can't remember how much exactly. And i've been running cleanly for the entire year in michigan. From 80 degree weather to 30 without any problems.
