pw50 power plate upgrade

Price: $52.99

Install this special CNC aluminum POWER PLATE under stock 50cc cylinder for a mid range and top end power increase. Your PW50 will rev out much quicker and run more efficient because this plate will allow the exhaust port to properly open at the correct time as the piston goes up and down. This TOP END MACHINE brand PW50 power plate is made in USA from quality CNC 6061-T6 aluminum.

Please note: cylinder milling is needed when fitting this power plate to bike.

Free instructions and & gaskets are included.

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.

Maxima Castor 927 Oil

Maxima Castor 927 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

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.
