The standard main in the TTR was a #148 30mm carb
with the 32mm Koso I'm running a #157..
not sure.. think it's got a #42 pilot .. standard was #40
needle... centre groove ?

but it's a bit lean on the pilot as it's rich on the main...
but the power jet takes care of that when you snap the
throttle open at low revs...

what I have found over the years to get the pilot right/close
if you can start a cold motor with out choke you are to
rich "big" on the pilot jet...

my bike is a dirt only so it not running at constant revs for
long periods " or even short periods "
so my jetting requirements will be a bit diffrent...
