New Evo owner. I have a 97 Badyboy and my left tank doesn't empty on ly the right one works. Hell i didn't even know that the left gas cap came off. My last bike was an 04 and they told you not to touch the left cap because of the fuel gage.

Also, after i removed the dash to have a look see what was going on. I found a what appears to be an overflow drain on the right half tank was melted off????


I don't understand why the left doesn't drain because that is where the petcock is attached. You would think the right would stay full and the left would drain!

Help please
Jamie

 

Left and right tanks are connected by a hose at the lower front of the tanks that transfers fuel from the right side to the left side. Tank's fuel should always be at the same level when the bike is upright.(liquids will seek the same level) The hose under the dash that connects the two tanks together is a vent line to prevent the left tank from forming a vapor lock. Right gas cap has a vent hole, left has no vent hole. Left side gas cap has left hand threads to prevent mixing up the vented cap with the non vented cap.
