Same as julie here Ted, unless you've very specific reason to shift for some reason. Very high spring rate would generate need to go upward.

Using their 7.5 viscosity in mountain bike forks as that seems to work well. These are (or the riders specifically ) are very sensitive to any additional and unwanted stiction hence my reference to how well this oil works. They are used in 35~40mm stanchion forks with coated aluminium legs and magnesium alloy lowers with low friction bushes fitted, literally everything to reduce stiction is welcome in their use.

philward:
I enquired on the forum shortly after the rebuild of my 500k2 about what fork oil to use as I found the bike was picking up all the small undulations in the road. I started off with ATF and following K2-K6's recommendations, worked through Motul 10w,ending up with Motul 2.5 w and that improved it considerably. I don't scrape the pegs but works well for my general riding.
