Hi Lukepentcof.

its 350cc or 11.8 ounces in the Clyma book, but that's for a 1986 onwards model. you can vary the amount you use to suit your style of riding anyways. I doubt it would be that far from the mark.

You can download the whole workshop service manual that has this info and heaps more from here. Hope this helps Thanks for using Fixya.

Use Yamaha suspension oil #01. Amount is 19 ounces. Oil level from top surface w/o cap nut is 3.15" to 5.51". I am sending you a link to a site where you can download a free shop repair manual. It is actually a bit complicated as you will see in the manual.
