Progressive Spring set up question R100 GS
I put some progressives in my 89 GS last week. I couldn't find any info from progressive, or from BMW, about how much, or what weight, of fork oil to use with those springs.
We went to a lighter oil, Aeroshell 4/5 weight, and put in a little less than stock - 390 cc's left, and 420 cc's right.
I like that the fork is stiffer than it used to be, but it feels kind of harsh, especially on washboard or small bumps. I'm wondering what anyone else used for fork oil, amount and weight with your progressives, or if someone has found a good recommendation on it.

Fork oil weight won't matter much, it's a stiff spring compared to stock.
Read your same post on BMWMOA, seems you're "not getting much" there, either.
So, to elucidate- I, too, have liked the stiffer Progressive spring in two front ends now; the third, not so much. I have varied both fork oil weight and amount and also experimented with pre-load spacers from 1" down to zero.
Bottom line-no appreciable change.
The lack of voluminous discussion on this subject probably says everything.
One either likes these springs or they don't.
Opinions are like internet connections- everybody has one.
