    hi folks,
    I'm rebuilding the front forks on my 03 GL1800, and installing Progressive springs. I have Bel Ray fork oil 20, and I was wondering if this was a good choice for oil density or is it better to go with the OEM suggested product?
    Thanks for all input.

    I use 10w Bel Ray and it works for me. I'm sure there are others who believe if pure Honda is not used you will have problems, but as I say have used it (Bel Ray) for 3 rebuilds and it works well. Hope this helps.

      Unless you are a heavy weight?. meaning over 270#'s I suggest you try 15w fork oil.

      I tried them all in my bike and yes I can feel the difference between 5w oils.

      20W was to firm.
      15W was better but I wanted to try 10W the next time a seal gave me an issue to see if I could get a smoother ride?..

      I couldn't wait for a seal leak so I pulled the forks and went with 10W and found it best for my 220#'s with a 150# co-rider.

        Thanks, I started to get seeping on the left side, so I changed to ATF, which I suppose is around 15W. I also disabled the antidive with a spacer, as I it felt very harsh going over bumps, we'll see what happens this season. No, I'm 168 lbs, but my SO is 210 lbs, and we almost always ride two up.

          Is changing the fork oil something easily done at home? The seals aren’t leaking, as far as I can tell, but I have RaceTech springs and wanted to disable the anti dive and thought perhaps I should change...

          An oil thread!

          Do we have an oil expert in the house.
          What do I get if I mix equal volumes of same brand fork oils.
          The mix is 10w and 5w.
          My maths says 7.5w. However I...

          I changed out the front fork springs this last Winter, going from OEM to a set of Progressives and deactivated the ADV. The bike handles much better, but the front is quite stiff. Since I'm replacing...
