I know the title is confusing. I have and an aftermarket tank and never found a good place to vent the tank. I don't like the one way vents because they I keep losing them while trail riding. Most dirt bikes have the hose vent down the steering stem but the DRZ doesn't have a hole in the steering stem nut. Well that's what I thought, until the other day when I greased the bearings and notice the nut cover pops off. easy fix. Just thought it might help someone else.
