Having clean oil in vintage motorcycles is imperative. Particulates in dirty oil score cylinder surfaces and gum up vital engine components. Unfortunately, those particles also clog vintage oil filters, which reduces oil circulation in your vintage Kawasaki engine. Changing your oil filter with every oil change is an insurance policy against engine damage. Z1 stocks EMGO, Fram and HiFlo oil filters for vintage Japanese bikes like the KZ1000, CB750, FJ600, FX750 and many others. We also have excellent prices on hard-to-find oil filter bolts for Kawasaki, Yamaha, Suzuki and Honda.
