Warnings:
It is not recommended to run lower than 50 psi in Penske Racing Shocks Motorcycle shocks, depending
on piston and shims being used. Lack of nitrogen pressure could result in cavitation which can result in
loss of immediate damping and rider feel.
It is also not recommended to run more than 300 psi. This could result in stress fractures in main
mounting components, which could result in failure of shock.
Always check with a Penske Racing Shocks technician on recommended pressures for a specific
application and use.
Troubleshooting:
Signs of Fluid:
If the area around the shaft bearing and shaft exhibits a small amount of moisture, this is normal. In
order to reduce friction in the system, seal squeezes are slightly relaxed to allow a small amount of fluid
to be wicked onto the shaft when the shock operates. If an excessive amount of fluid that may “pool”
on the top of the shaft bearing is noticeable, there may be a seal problem. Contact a Penske Racing
Shocks representative at once.
Loss of Gas Pressure:
An obvious sign of reduced or no gas pressure is when the shock (without a spring) will not return to its
fully extended position after being compressed, or it gradually becomes much slower when reaching full
extension.
It is recommended that gas pressure be checked before each race. Gauges to properly check gas
pressure are available at Penske Racing Shocks, as well as at authorized dealers and distributors.
