Yamaha Fzs600 fazer how much fork oil?

Answer 1

I assume you have a '98-'03 model with stock springs. If you have changed your springs for aftermarket products, the below specifications do not apply.

Use either of two methods:

A) measure 465 ml per fork leg

B) measure 132 mm air gap (room from the surface of the oil to the top of the fork without the springs and with the fork fully compressed)

Note 1: It is very important to have the numbers correct and - even more important - the same at both sides. If you miss out on this, it may result in poor handling and even have disastrous consequences.

Note 2: Measuring air gap is recommended over measuring volume, and not especially more difficult, it will be more precise and yield better results. You can use any measuring device dropped in at the desired length and fill until the oil slightly touches OR you can overfill and suck out the excess oil with a hose that you drop in at the specified depth.

Note 3: Recommended oil is a grade 10W fork oil.

Addendum: You can tweak you forks according to your liking, e.g. by putting 15W grade fork oil in or reducing the air gap by a few millimeters. But make sure you know what you or doing, If you do not understand the impact of these changes just follow the recommendations.

Succes!
