|Instructions for Adding Fork Oil to Storz/Ceriani Inverted Forks
Oil Quantities and Type of Fork Oil
To drain fork oil, unscrew the drain screws found of the backside of the lower fork leg near the front axle. Due to the internal cartridge design, a significant amount of oil will remain in the fork after the drain screws have been removed. To properly drain the fork oil, it will be necessary to pump the front forks several times, then allow the bike to sit and slowly drain. It may be necessary to repeat the process several times.
You must use lightweight Cartridge Fork oil, we recommend Golden Spectro GS85/150 which is approximately 3W viscosity. Do NOT use fork oils for conventional H-D forks.
Refill Quantity: 420cc each leg for 31/32" length fork, 490cc for 33/34" length fork
NOTE: If you find the fork is too soft and bottoms out easily, you can add 50cc to each leg quantity. This will decrease the air space inside the fork and effectively increase the spring rate.
