Im in the process of stripping the forks out on my RC to replace the seals (and bushes if necessary).
I don’t want to run any air in them once they’re rebuilt as I believe doing so contributes to premature failure of the seals, so my question is what is the best weight oil to use with standard springs and no air assistance? I’ve used 10W in my 1100F which is fine for that bike, but would the R benefit from a heavier oil?
When i fitted new Hagon Springs in mine they supplied 10w oil,just filled to the 150mm air gap they recommend,springs out fork fully compressed, forks feel better with new springs and oil, old springs were a bit tired
Hi Keith. Thanks for the info. Which Hagon springs did you go for, I had a look on their site a while ago for the air gap and they have 2 sets for the R. 1 set for a 1980RC !! and a set for a partly covered 1982 R!
They are incorrectly marked as 80 on Hagons website, i phoned them when i bought mine and they pointed out that they are listed as SC08
Found my reciept and the ones supplied were” 400-207-00 Honda CB 1100RC (SC08) 80 (10) 150mm Air gap”
I think the partly covered 82 are RB ones with the year also wrong
I have also seen these recently on ebay germany with are a bit cheaper
