do some bikes use the FCR-MX without a main air jet?
I just bought a used FCR-MX39 to use on the DRZ, and it came without a main air jet. so I checked the FCR-MX41 that I have laying around, and it was also missing the main air jet. :thinking:

Not main air jet rather the slow air jet and yes, it is removed.
If you left it in, you'd have to run a very small pilot jet and that would tend to clog easier. So with the slow air jet out, you can run a more normal pilot jet, typically a 45.

I understand that the slow air jet needs to be removed, that's not the question.
my question was, why do these carbs not have a main air jet? is this normal?
(I know that a 200 main air jet is recommended for the DRZ)
