2018 vee, bought it used with 3800 miles and still sorting it out. Previous owner liked to tinker and I am anal. Not a good combination. Pulled the tank to put the oem air filter back on from a k&n. Also installed original counter shaft 17 tooth sprocket and removed lower kit and put front forks back to the top of the mounts. I guess you get the point. There are two drain or vent hoses to the fuel tank and one small vacuum looking hose tied to the other two not plugged to anything. Where does it go. Has a 90 degree turn at the top. Thanks for any help or advice on getting it back to stock.
