Title: Fork oil
Post by: greg1953 on 27 September 2014, 12:29:38 pm

Can anyone recommend which fork oil to use as I'm about to service the front end ?

Gen 1 or Gen II?  Standard springs?

Assuming you're average weight and not the last of the great late brakers, you could probably benefit from slightly less viscous oil to improve the high speed damping reaction.  Or in other words, make it a bit less choppy on rougher roads.

I used 5w Silkolene RSF when I had stock forks and springs in mine. 

Confusingly, the viscosity index numbers quoted for fork oils aren't consistent like engine oil ratings, meaning that some 5w oils will be thicker than others and so on for other viscosities.

Silkolene RSF for me too when I gave my front forks a recent overhaul and new seals. Actually that's a lie. I stood and watched whilst a mate did all the messy bits which was basically the whole job  :\

silkolene use a seal sweller which can lead to stiction on the fork seals. just FYI

Yes but a blob of red rubber grease under the dust cover combats this nicely and there's no stiction evident on mine  ;)
