How goes it? Missed you and Mosport/Shannon this year.
The only info I have on hand says 135-145cc of 10w-30. per leg.
But that's from a third party manual, not a honda service manual.
If you are racing it....actually even just riding on the street I prefer at least straight 20 wt fork oil, or heavier if you can find it. With heavy oil these old forks almost feel like they are doing something
Hope to see you next year some time.
