Want to have your bike look retro in its smallest details? I think that Toxic Choppers is the first company offering a finned sand cast oil cap to match other ribbed custom parts, like the ones offered by Crime Scene Choppers and others.
It is provided with a “no leak” double Buna N o-ring seal. This finned oil cap will fit on any Harley or custom oil tank with a 1.25” ID push-in filler neck. Creating a custom oil tank? Just use 1.5″ X .120″ or tubing for the filler neck also provided by Toxic Choppers.
