Bolt Kits

Those old, worn out bolts holding the covers on your vintage Kawasaki engine aren’t just an eyesore. When steel ages, it becomes more brittle over time. And the steels they made 40 years ago aren’t up to today’s standards. Vintage Japanese performance engine fasteners are also susceptible to high-RPM vibrations and the stress of being under torque for years. These factors are a recipe for a snapped engine cover bolt. Z1 offers 400 different engine bolt kit options to help you renew your old ones, or complete your Japanese motorcycle restoration. We have engine bolt kits for vintage Japanese bikes like the Honda CB750, Kawasaki KZ1000, Suzuki GSX1100, Yamaha YZF750 and many more. We polish our stainless-steel Allen-head engine cover bolts for 24 to 48 hours to give them a bright and even shine. When you’re ready to give your vintage Big-Four motorcycle a fresh, eye-catching appearance, look to Z1 for your engine case and engine cover fasteners.
