um can i see vid of your engine in action it sounds insane
187cc with a bigger cam and most likely higher compression i was using (mikuni) think i settled on a 32.5-37.5 depening on weather for the pilot, and around the 125-130 for the main.....
If you are running 50-60 on the pilot, thats not right :/ neither is the 140 for the main....
The main problem with them is the taper on the needle... i had to stick mine in a drill and sand paper it to get a little more into the mid range...... OR just get a real carby
EDIT: as u dont give us much info on the motor we cant actually help u a great deal mate need specs.
If u are doubtfull on my tune have a look :- YouTube - Yx187 helmet cam
The miss on the bottom end was from my idle jet backing out, and this was running OVERLY rich at the time...
also something for a look see...

To let you just how different they are, here's both side by side
well just as a quick review,
even with the carb running funny down low the 155z hasnt got a chance.
we went riding yesterday(bush riding) our mate has a 155z and straight line and track style riding the 155z gets smoked, and not just a little bit..
what do you expect 196cc is pretty much going to smoke everything on a open track.
