Engine - Top-End

It can be tempting to throw in the towel when a pulled spark plug from your vintage Kawasaki comes out drenched in oil, or blue smoke starts fogging the road behind you like a mosquito abatement truck. But don’t worry; you can handle this. That oil is coming from one of two places. It’s either valve blow-by or worn piston rings. KZ900 and KZ1000 piston rings from Z1 are direct OEM replacements. We also have standard and oversized CB750 SOHC intake valves, KZ900 square keeper intake and exhaust valves, GS1100 and GS750 intake valves, KZ650 intake and exhaust valves and more. Z1 is also a great source for OEM equivalent cam chains for Japanese motorcycles from DID, K&L and EK, as well as Kawasaki cam chain tensioners. And when it’s time to reboot your vintage Japanese carb holders, Z1 has you covered.
