Motorcycle Oil Tank

Every Engine needs to stay lubricated. This bike is no different. And to do so requires some way to keep circulating through the engine. To properly handle this, most bikes have an oil storage tank in which to hold a supply of oil and lines that run both to and from the engine. A good quantity of oil resides in the tank to make up for any leakage or consumption that may occur. There is usually a vent line that vents the oil tank to the air to prevent vacuum buildup.

My oil tank on this bike also came off ebay. I was willing to pay a bit more for it since it was made by the same company that made the frame. It also has a space to mount the battery for the bike. I figured by doing so, all the mounting holes would line up and installation would be a breeze. Boy! Was I wrong! I will say that I like the overall style and the lines of the tank. I think it really goes with the overall “feel” I was shooting for. So…what’s a little fabrication for a great look?


The front lined up without a hitch, but there was absolutely nothing to mount the back of the tank. I had no other option than to fabricate some sort of rear mount bracket for the tank. I started by buying a bag of shock mounts from a seller on eBay. Next, I had to get some bar material to build the basic mount. I drilled and tapped two holes for the shock mounts to screw into. Then I had to make a angle piece to mount the bracket to the frame. Below are some picture that show the assembly.
