I was looking around for fork oil after my interesting time in France, and found that using the Weight Number as a comparison between brands is meaningless. For instance my Girly should have Kabaya 10W which in the linked table has a viscosity of 37.2. Other brands 10W vary in viscosity between 32 and 47 :bug_eye Good luck with getting it to handle as it should with those numbers :icon_lol:
I'm going to try Silkolene Pro RSF 7.5W as its very close at 37.19.
There's lots out there, but here's the table I used:
https://transmoto.com.au/comparative-oil-weights-table/
Have always used Silkolene 15wt never used anything else and the quantity to taste,just don't expect a smooth ride on a cool day for the first 30 miles till the oil has warmed up.
For those with the old forks I use 720cc .
720cc is what my book says to Chris. Which Silkolene 15W? There's 48.45 and 92.95 which reads as "stiff-ish" and "treacle" :bug_eye compared with the recommended 37.2.
I guess it's the 48 one, which is still quite a bit stiffer than stock, but then again, you'd need that.
I've just used the Silkolene tool (here : http://fuchsmoto.lubricantadvisor.com/default.aspx ) and it comes up with what I ordered and which is near the original spec. I aknowledge you need stiffer forks Chris hence the 15W but nice to know I made the correct choice by two different paths.
I used RF 15w last time, liked how it road but 15-18k later when it came out it was filthy and somewhat grey. I fear it started some early wear of my forks.
