I reckon jims on the money, question is what weight you using, if its anything like my 125E, i reckon maybe 20.

I run between 120mm - 140mm from the top on my YZ 250 which has the same forks depending on the track. Closer to the top the firmer they become as they compress. 150mm might be a bit soft if you dont run air in them, I dont, but OK depending on what pressure you run. I use 10w oil, personal prefference only.
