One of the vents on my '99 WR broke off last fall, on the older style carbs there is a plastic vent coming off each side of the carb. The vent "t's off where one vent tube goes straight down the other goes up and then makes its way down or in my case to the airbox. In order to fix this problem, I plan to plug the broken end and run the tubes off the "other T". My question is ....do I need to vent it in both directions or can I just vent it one direction ...either under the motor with the other vents or to the airbox? Thanks in advance!
