    According to my Haynes manual:

    Oil Capacity - US 93/94 & UK RRN/RRP: 509cc
    - US 95 & UK RRR/RRS: 564cc

    Oil level - US 93/94 & UK RRN/RRP: 110mm
    - US 95 & UK RRR/RRS: 112mm
    (level from top of the tube with spring removed and leg fully compressed)

    Oil type - US : Pro Honda Suspension Fluid SS-8
    - UK: SAE 10W fork oil

    On the last item you'll find as many opinions on "best" weight as sand on the beach.

    Crud the previous owner stripped the head on the hex but at the bottom, preventing me from being able to complete the job myself. Need a shop to get the bolt out almost tempted to just have em do the whole thing

    I need help, the microfiche does not have the listing for the part. I finally got the fork apart, but at the top where the damper settings are under the top fastener that holds all the parts in is a small round spring that holds in a bearing that I assume is for the clicks when adjusting the pre-load or dampening was corroded and snapped when taking it all apart. I cannot find a part number for this and depending on how important this is I would like to be able to put the fork back together when the rest of my parts come in. any help on this would be greatly appreciated. thank you all so far everyone has been a huge help.

    Hi
    This is the microfiche from lings honda in the UK. Don't know whether this will assist in identifying the part you're after?
