SmJunkies,
I just got my Mikuni TM40 From procycle.us for my DR650 but there is a problem.
The carb came prejetted for airbox, after market air filter, and exhaust. I have those
mods plus one more.

So it isn't jetted properly because i have a JE High Compression piston 10.1:5

I want to rejet before i install it. The current specs are:
  1. Main Jet=150
  2. Pilot Jet=22.5
  3. needle Clip=3rd position (from top)

What specs need to be changed ?

Please help and thanks junkies
