You can run all the vents to the intake snorkel except for the carb vent. It will cause a vaccum and draw fuel into the vent line and cause your atv to stall. You can run a long vent line from the carb up the side of the snorkel or run it somewhere else to get it higher. I ran mine to the headlite pod. There are many threads on this site to show you exactly what to do. Just do a search.
