I pulled my tank for the first time to do some air box mods and did not realize that there are two vent lines, I only saw the upper one and didn't see the lower sorta hidden one until I put the tank back on. I put the line back on the obvious bung on the tank but after a test ride noticed the other end of it was dangling and getting melted by my header, obviously not what it's supposed to be doing. Does the other end of this vent line go to some super secret location or does it just dangle to a more secure spot and vent to the open air like the upper one does. Thanks and forgive my ignorance, I have searched quite a few places including my factory manual.
I don't recall there being a 2nd vent line. The only other hoses I remember are the line to the fuel pump and the crossover hose. Did it attach directly to the tank?
One is the "vent" the lower one is a drain for the gas cap area. re route it away from the pipe and you're good to go. Take the gas cap off (everybody please) and you will see a hole at about 11:00, that drains the caca out of the recessed area. Some bikes had a screw where the hose fitting should go, if you have a screw a little below the vent fitting, remove it , put in a hose fitting and install a drain hose, it'll drain out gas if you overfill it, rainwater, wash water, etc. I found this out the hard way at BtoV when my tank had a quart of water in it from washing it ! Have fun.....
Thank you so much, I thought that was what was up just making sure. Bike is all weird after my switch to a pod filter and re=jet to my current altitude, trying to eliminate the possibilities. Guess I will be back in my carb tomorrow.
To clean up my drain hose situation I got a small Y from an auto parts store and connect both drain hoses together, that way I only have one hose running down to the bottom of the frame. Of course I only did that after aliens abducted my emissions canister.
