Hi Tomas,

Here is the service info for your bike including fork oil etc.. http://vintagechat2.tripod.com/YZ_DATA_SHEETS.pdf
Also, here is a great magazine review of the H with suspension mods to do... http://davestestsandarticles.weebly.com/uploads/4/8/4/5/4845046/dirt_bike_february_1981_yamaha_yz125h.pdf
If you want to spend some money, then call Terry Hays at Shock Treatment and get all the fruit.. emulators, springs etc.. ride like a rolls royce....

Cheers,
Alex

I run 20w & start off with 110-120mm from the top, leg compressed without the spring, no added air pressure.

Test & add or delete 10ml at a time to suit.
