Which fork oil and how much ?

[mcyoungy]

Standard is 5w? Depends who you talk to. Yamaha claim it's 0w. SAE wt is not a good number to use tbh when discussing fork oil. You need to look at oil viscosity and quality. you will find that one man's 2.5w is another's 15w as the viscosity is the same.

This wiki gives some good info on oils:

The OE fork oil is listed there as Yamaha 01 fork oil - it's a Kayaba oil.
