From 1981-2014 the Yamaha PW50 has been the most popular motorcycle ever manufactured.In the early 1980's it was named the Yamaha YZinger then later the PW50 name was given. For 30 years this little 50cc automatic 2-stroke dirt bike has been virtually unchanged and most all parts on all years are interchangeable.

PW50's are very durable dirt bikes. They will last almost forever, being bought and sold or passed down through the family over the years. If you got your hands on a used one you may need to replace and update a few parts to freshen it up or it may need a full rebuild from time to time. Chances are most money replacing warn out or broken parts is a great investment.

Many people do not want to run a 60cc top end kit on their PW50s because it's totally illegal for many racing tracks and clubs in 50cc classes. This new PW50 Power Plate isn't legal to use everywhere some race tracks do allow it because the PW50 retains its stock 49cc displacement.

PW50 Oil Injector Block Off Plug

One of the best performance upgrades for the PW50 is installing our oil block off plug. Pre-mixing your oil and gasoline will eliminate the standard oil pump assembly. The oil pump is not accurate most of the time, sending either too much or not enough oil into the engine causing big performance loss. Even worse, an oil-deprived engine will result in premature wear or in many cases extreme engine failure. Eliminate the risk and gain performance - install our Oil Block Off Plate.

*We recommend using pre-mix Super unleaded quality gasoline at 40:1 ratio with Maxima brand "Super M" premix oil.

This is for use on PW50's or PW80's and not intended for use in oil injection systems. When blending with alcohol it normally requires more oil. Care must be exercised when blending with low specific gravity (below 0.730) race gasoline or aviation fuels and in temperatures below 35ºF as separation may occur. Separation may also occur in alcohol containing a high percentage of nitromethane. Check before using.

Castor 927 is a unique blend of highly refined castor oil, a specially prepared synthetic and an additive system that reduces carbon and gum formation and provides excellent rust & corrosion protection. Castor 927 also contains an exclusive additive that keeps power valves cleaner and working properly. For all of us that wish to keep our air and water cleaner, Castor 927 is biodegradable. Castor 927 keeps on lubricating; where other lubricants turn to carbon or vaporize, and provides extra protection on cylinder walls, bearing journals and other critical areas at temperatures much higher than other lubricants. Recommended Premix Ratio 50-80cc (24-32:1)

Available in 2 sizes, 1 Liter (33.8 fl oz) for $19.99 or 1 Pint (16 fl oz) for $10.99
