Hello, have you found something yet?

Hah ha ha! Good luck finding anything for the Sachs forks. I emailed Sachs directly and never heard anything back. I have tried sourcing parts for these forks and its like pulling teeth.
The good news is that they are a basic cartridge style fork (i think) so the fundamentals are the same as any other out there.

I'd like to know exactly what kind of fork oil they fill the Sachs with at the factory. I want to keep the valving feeling the same after an oil change. I read elsewhere that they use the GRO fork oil, 5wt.....
BUT... I have had a bad experience with just an oil change on WP forks in the past. The fork oil change felt like a total revalve to me. What went in was a totally different viscocity than what came out. The new 5wt was very different than the old 5wt. (I am not an expert, but I feel totally qualified in saying that Belray cartridge fork 5wt does not feel like factory WP fill at all)..
I would like to see the Sachs internals and service manual as well.

Bailey mate.. I dropped my Sachs oil and it was a blue/green stock and replaced with Silkolene Racing 5w. I can also tell you from a Reliable source in Australia that they use GRO and it is indeed an orange coloured oil, which would be the same as you suspect.
is it... cool. the distributor lives locally here, i'd better get in contact with him.
Anyone have any thoughts on GRO products? I've heard theyre good but never used it.

Lonetree.. Sorry if my post was a bit misleading.. Two parts to it..
1) Bailey wants the same oil and knows its orange/honey coloured
2) Nutty Prof said he uses GRO in forks he works on, which is orange coloured (read on a post where they accidently put Silkolene coolant in a fork -- The green/blue coloured)
I've been using GRO Synth 7 and their 10W-40, premix and trans fluid respectively. The premix smokes a bit until the bike is up to temp but runs very clean. No spooge. Light oily ring around tip of exhaust. Nice coating on the crank when I did my first pull down. Bit of carbon build up on powervalve. Not spoogy at all.
The trans fluid I'm a bit so so about. Theres definately some drag, bit notchy when cold, and somtimes a bit tricky finding neutral.
I guess they do a good job for what they cost. I'll probably go Amzoil Dominator once I'm out of Warranty period. I've been using GRO as thats the warranty terms stipulated by the dealer here.
Great! In the process of subtracting some oil from my Sach's fork, I noticed that the oil was the color of fresh motor oil, a light honey color.
Jakobi, maybe the down under bikes got different fork oil from the factory if yours was a blue-green? Belray is that color.
The Belray oil in my old WP forks on my KTM acted very harsh, lots of stiction. If I sat on the bike, the forks would not move unless I pushed on the front end.
I will look more into the GRO oil and if I can confirm for sure that it is the Sachs factory fill, I will use it.

If this is what Sachs uses for the 5w factor fill:

Then I would get the 5wt with the viscocity of 21 in another oil brand that I can actually buy here in the US.
