Do you have a Yamaha RZ350 RD350 YPVS 1983?
This was always going to be a project for the future… I didn’t have time, and still don’t, to build it and for the longest time I didn’t have a real plan for it.
Is there a Yamaha Banshee 350 with YPVS?
A different version of this motor with no YPVS was also used in the Yamaha Banshee 350 ATV, which was produced for some markets right up until 2012. It is also raced extensively in Vintage racing leagues, as well as its own racing leagues, often dubbed “RZ cups” in Europe and Canada.
What kind of motor does a Yamaha YPVS have?
One thought was to go back to all OEM and build a proper LC2, after all they command strong money as the first YPVS models and they are a nice bike. another was to get a radical 500cc motor and ‘go big or go home’!
When did Yamaha stop selling the RZ350?
Sales of the RZ350 were discontinued in the US after 1986, as Yamaha decided the two-stroke would use too much of their United States Environmental Protection Agency fleet emissions quota, and limit sales of larger displacement bikes, which were more popular sellers.
What was the YPVS on a Yamaha RZ350?
The RZ350 had a variable exhaust port valve called the Yamaha Power Valve System (YPVS) that was controlled by a basic computer. The YPVS could open and close the valve to move the height of the exhaust port and thus affect the exhaust port timing. This provided lower RPM torque while retaining high RPM power.
