Kawasaki vulcan 750

Quien me puede ayudar con mi kawasaki 750, pues en varias ocaciones cuando estoy en marcha se me bajan las revoluciones como si se fuera a apagar, que puede ser eso, ya limpie el tanque y revise las bujias y todo estaba bien.

llenas el tanque de gasolina hasta arriba? eso le puede tapar el tubo de respiro.
chequea la parte (tubito) debajo de la tapa de gasolina, y soplalo a ver que no este tapado. es el roto que esta debajo de la tapa arriba en el tanque.

chequea este pstado www.vn750.com/forum/showthread.php?t=17572

Don't know if this will help or not. You may want to check out the diaphragm in the petcock or the vacuum supply to the petcock. The bottom line is the vacuum supply and the side lines carry fuel to each of the carbs. The vacuum activates the diaphragm to allow the fuel to flow. Could be you have a weak diaphragm or for some reason are loosing vacuum. Just a suggestion.
