#90622 Bad Man (User) Live For The Ride! Fresh Boarder Posts: 16 Gas Tank Vent!! 3 Years, 11 Months ago   My question for all of you is this; I've notice that my gas tank creates a vacuum when the weather starts get a lot of moister in the and the temp falls, but on the days that are sunny and warm I have no problems.. About 4yrs ago I wrecked said bike and have since rebuilt and took it on a trip to the lower 48 from Alaska, When we got into Canada we hit nothing but rain and mud from construction the bike kept dieing, we would stop and cleaned out everything and kept going that was the first time it has ever happened, no problems when we got to warmer climate, was wondering if that tip-over plug (for lack of proper name) might have something to do with it? The bike still does it sometimes. Thanks for the help, Stan Church   Logged     In Alaska We Ride Till The Sun Goes down, (OH MY BAD!)

Check and make sure the line isn't kinked and blow thru it to make sure it isn't plugged.   Logged     My Site Black Ice is Shiny, Black Ice is Deadly, Ya Wanna Ride My BlackIce?   The administrator has disabled public write access. #90628 Musky (User) Platinum Boarder Posts: 15137 Re:Gas Tank Vent!! 3 Years, 11 Months ago   Do you still have the rollover valve in the tank vent line?   Logged       The administrator has disabled public write access. #90644 StarMyram (User) STARVE to RIDE, RIDE to LIVE Gold Boarder Posts: 906 Re:Gas Tank Vent!! 3 Years, 11 Months ago   Check that little 1/8 inch rubber hose that hangs out just in front of the rear wheel, to the left side of the spring/shock area. It may be clogged with all that construction mud. I think this hose vents the fuel system somewhere. Mine usualy has gas fumes coming out of it when I park the bike on a hot day, so I know it's a vent line that's connected to the fuel system somehow. It also collects a ball of mud when on wet clay roads.   Logged     A Fallen Man is not a failure.   The administrator has disabled public write access. #90701 Pop Rivet (User) Platinum Boarder Posts: 3123 Re:Gas Tank Vent!! 3 Years, 11 Months ago   StarMyram wrote: Check that little 1/8 inch rubber hose that hangs out just in front of the rear wheel, to the left side of the spring/shock area.
