We have seen photos of K1s having either a Kawasaki or a Yamaha fuel tank. Dustin Motzouris explains why there is a scope of using either one: We run stock or this Yamaha tank since, it just allows extra fuel capacity for the triples. Some boats we use Kawasakii SXR tanks it just depends. We also have internal fill system or regular fuel cap. It's the customers choice. The internal fill I feel is safer as no contamination of fuel through a faulty fuel cap.
