SOURCE: yz125 rear shock amount of oil on

The volume is less than about 1/2 quart - it's usually not measured going in since you fill the shock completely - there's no need to measure. Some guys assemble the entire shock, then fill with oil and cycle the shaft, then install the bladder cap last. My method is to install the shaft and seal head and the bladder, then put about 2 PSI in the bladder, then bleed through the compression cap. My method is a bit more complicated to explain, but it's effective at eliminating ALL the air from the oil and it keeps the bladder from being installed in a collapsed state.

As far as the nitrogen charge - 145PSI is stock. 130-160PSI is typical.

Hi Niven

There are also 2 separate drains/fillers one for the transmission and the othe for the crankcase . The measure is 620 ml per side, although some guys run up to 700 ml on the transmission. 10W-40 is the correct weight for the engine side. On the trans side a Transmission specific oil in an 80W or 85W grade. Maxima Extra full synthetic is the best oil you can buy for the engine. Maxima MTL is the best for transmissions.

read your owners manual. the crank case breather tube has a plug on the end of it and needs to be drained periodically.if this is not done over time the tube fills with oil and then dumps into the intake tract.
