Brand new CappilliniMotoOil Filter kit. This converts the CB350 to a real oil filter. It includes a chain driven oil high flow oil pump and a CappiliniMoto Billet aluminum oil cooler. These guys make some of the nicest vintage Honda racing parts.
This kit costs over $1,000 from CappilliniMoto plus tax and shipping from Italy. I'm asking $550 shipped in the continental US.
