Stalling, Spitting, Sputtering, Starving for fuel??? (Check this Out!)

In today's video we are going to talk about an easy fix for your dirtbike. The vent hose on the gas tank cap caused both of the x-pro storm 125cc dirt bikes to stall, surge, bog, and eventually die. At first we thought we were having carburetor issues , but soon determined it was the valve in the vent hose sticking. This causes the tank not to be able to breathe and causes the bike to starve for fuel.
