Front end washes out a lot, need help.

[Roberton]

Hi, i used to ride a 125 because i think two strokes doesnt wash out like a 4strokes. So yesterday i switch to the yz250f 2009 but my front wheel washes out a lot at the corners(flat corners) i know flat corners are hard but on the 125 i can turn on flat corners ass hell, im faster on the 125 than the yz250f ): so i think is my suspension set up the problem,no?

Here's my front suspemsion ser up.

Compression 80
Rebound 70
Spring rate 55
Preload 50
Oil level 80
