Since the mid 1970es the name PBI stands for high quality sprockets. After precise manufacturing the transmission sprockets are electroless nickel-plated against corrosion. Electroless plating provides a uniform deposit thickness, disregarding the shape of the plated object.
Socket head screws for the supplied lock washer will not clear 1965-1969 primary housings. If you can't machine the lock washer and use countersunk screws, use OEM 35216-36 lock washer.
PBI sprockets →1979 need WW 77-500 to be installed between the sprocket itself and the maindrive spacer.

Tsubaki Alpha RQ2 530 Secondary Chain
The Alpha type chain by Tsubaki is smooth running with a minimum of power loss combined with the benefits of X-sealed inside lubrication that provides a longer chain lifespan. A great chain for hi-torque, hi-horsepower performance bikes. Available as Alpha XRS in plain steel and RQ2 with gold coloured outer links. Same chain, same quality.
Tsubaki Sigma 530 Secondary Chain
The Sigma XRS 530 is the highest strength chain available from Tsubaki. While the steel coloured version keeps this name, the version with gold coloured outer plates changed it to RQ1. Quality and strength of course stay identic. The X-seals keep the factory-applied lube inside the bushings and minimize friction caused power loss. The choice for top horsepower bikes.
Tsubaki Delta 530 Secondary Chain
The Delta QRN 530 is a non-sealed high quality roller chain. The bushings between roller and rivet are made from sintered metal and oil impregnated (HSL), which in turn results in longer service spans. The side plates are nickel-plated for corrosion protection and good looks.
