Title: Was there ever a final decision on fork oil
Post by: Seamus on October 07, 2010, 05:35:20 PM

Looking to refill the front forks on the K2. As already known, the original manual recommended 10-30 oil. Was there special fork oil in 1972?
What is the modern view? I was thinking of using a modern 10-20 fork oil. Any reason not to?

Cheers

I'd go with that, seems sensible. If you go too high it starts to make the bike bounce on the partial hydraulic locking rather than deflect over small bumps.

Thanks Ash. That was my gut feeling, but it always helps to tap into the experience on this forum.

Cheers

There was no specific fork oil back then and Ive never seen 10-20. 10, 15, 20 yes but not a multigrade in fork oil

I put 10w40 mutigrade oil in mine once because I didn't have anything else but it made it a bit too solid.  Now, I use only single estate unfiltered extra virgin olive oil.  ;D

Joking apart I think off the shelf fork oil does the job fine.

I used 20w in my F2 forks

It seems all o.k to me

I just went into Halfords and bought a bottle labelled "Motorcycle Fork oil", works for me.
