OK I hate a wasted thread, and I searched for jetting info already.
Sudco, Keihin, MX south, all have jets and info, but it doesnt seem like they go small enough.

I swapped out filters to a two brothers and they recommend a 85 main and a 40 pilot. 022-2-MJ85 and PJ40. Where the heck can I find these? Where is anyone ordering small jets?

Thanks.

Anyone know what the jetting is for a 138 or 143 CC upgrade? That may be my next mod. :nod:

Most of the time a bigger displacement is "jetted" with a bigger carb on most of the pitbikes. The carbs are pretty darn inexpensive and getting the parts such as jets is pretty difficult.

What carb do you have? In the 138 Lifan, a 22mm Mikuni with 15 pilot and 95 main works perfectly. With a bigger displacement, a 17.5 pilot and 105 main works well.
