Help needed,  cant seem to cure the forks on my 200 from topping out,  i have 220 ml of 10 wt oil in each leg , have fitted new springs from inmotion with a 50mm preload spacer . Have tried different lengths of preload from 35mm to 65mm and also increaseing oil quantity upto 280 ml in 10 ml increments but still didnt make them any better.    Any suggestions would be appreciated.

I had a similar problem on my Beta TR34. The rebound on early forks isn't great. I tried various things but in the end settled on heavier oil and it stopped the top out.
