It's very easy to over tighten the triple clamps, i think the spec in the manual is to tight? I made this mistake at first.
I think your have to go heavier with your shim stack with the 5w oil.
I tried 5w, but changed it straight back because I couldn't get any rebound.
1, 22x1.0
2, 21x1.0
3, 19x1.0
4, 19x1.0
5, 18x1.0
6, 17x1.0
7, 15x1.0
This is my rebound stack with 7.5w oil, I run the same spring as you.
And yes, you will need a 22x10 at the top, maybe two with the 5w oil.
I'd be interested to see where you get to with it, keep us informed please.
