The Zephyr Zone

So, I can't help noticing that Japanese and other customisers use what looks like a Z1 or Z900 tank on their Zephyrs. In my opinion they not only improve the look of the b...

So, as well as replacing the HiVo chain and the cam chain, I bought a set of starter clutch springs and a new starter sprocket from Cradley Kawasaki. Have f...

Fitted new starter clutch, problem went away. Now, 5k miles later, the starter motor just spins over, won't tu...
