RZ350 Petcock Upgrade by RZs Unlimited For Yamaha RZ RD350 LCII YPVS F1/F2 83-95

Description: RZ's Unlimited Japanese Petcock Upgrade for Yamaha RZ350/RD350 LCII YPVS F1/F2 1983-1995 If you have the OEM Yamaha RZ350 petcock, only ride the motorcycle with the petcock adjustment knob turned to the "On" or "Reserve" position. To make sure your petcock is working properly, remove the main fuel delivery hose when the motor is not running and make sure that there is NO Fuel Flow when the knob position is set to either the "On" or the "Reserve" position. The "Prime" position flows fuel continuously whether the motor is running or not and is only used to fill the float bowls when they have been stored empty or after a carburetor rebuild. If your petcock doesn't completely shut off or drips fuel with the motor not running, it will, eventually cause fuel to enter the lower crankcase and the left side exhaust pipe. To avoid a motor hydrolock and a damaged connecting rod and or crankcase, make sure your petcock does not leak, if it does, evacuate all of the fuel from the exhaust pipe and lower crankcase before attempting to start the motor. If the petcock is leaking, we recommend replacement as there aren't any Yamaha rebuild kits available to repair it properly and aftermarket parts are not reliable. Some Yamaha replacement parts that are available for the original petcock are not the ones needed to solve the leak of the main fuel delivery passage which occurs when the motor is not running. This common failure is caused by a faulty diaphragm assembly which Yamaha does not sell which is why we produce a quality Japanese non-diaphragm replacement petcock that will not leak. The RZU replacement petcock retains the same fuel flow but has a positive shut off position with a Recessed Shaft that accommodates the original Yamaha RZ350 adjustment knob. Please see photo number 3 and photos with the side cover. An additional part is available to extend the shaft to make it the same as the OEM position if desired. For European RD350 & RZ350 F2 1986-1995 the shaft is the same length as the original OEM petcock. The original Yamaha RZ350 petcock metal 90 degree fuel hose elbow must be reused. Instead of having a "Prime" position and the need for a vacuum hose, the RZU petcock has an "Off" shut off position instead, and retains the "Reserve" and "On" positions which function the same as the OEM RZ350 petcock does. Our RZU upgrade kit includes the replacement petcock, main gasket, sintered bronze element in-line fuel filter, longer fuel hose to metal tee, 2 fuel hose clamps and installation instructions. The in-line fuel filter fits well in the limited amount of space offered, and prevents debris that passes through the petcocks mesh screen from reaching the carburetors. Best of all, the RZU petcock won't leak like the original Yamaha RZ350 petcock is prone to. We carry all necessary replacement parts for the RZU petcock should they ever be needed. NOTE: The original OEM Yamaha petcock "metal 90 degree fuel hose elbow" and "selector knob with screw" must be reused on the RZU petcock. "Regular" JB Weld (not Kwik) epoxy is required for elbow as shown in picture 3, detailed instructions included. All shipments are insured & sent USPS Ground Advantage.
