I have a 95 SWS 150 Yamaha. I rebuilt the carbs and set the adjustment to 1 turn out. The manual calls for 3/4 to 1 1/4 turn out. My motor is still " lean sneezing " and stalling out. Will an increase out or in help with this? Or any other suggestions...

did you perform a link and synch?
could be a poor performing fuel pump, does pumping the primer ball help?

could still be trash in the carbs, in the low speed jet or air adj screw.

pumping ball does not help.
Excuse my ignorance, but how do you do a link and sync.

i did remove and dismantle the carbs looking for any debris. i found nothing.
