progressive springs xtz 660
 

I recently upgraded the suspension on my xtz660. I firstly put a hagon on the back and it greatly improved the road handling. A few months later I put hagon progressive springs on the front.

The set up works well at road speeds above 80 Km/h and has improved offroad and dirt road performance.
But at road speed of bewteen 50 km/h and 80 Km/h there's an irritating "bounce" in the front suspension.

I have 10 weight oil in the forks

Any ideas for improvment?
