KTM 350sxf 2013 Suspension?

I have ordered a KTM 350sxf 2013 and I am not sure if I should also order stiffer springs. I have approximately 200 lb (92kg) completely geared up and the manual say that the standard setting is for riders between 75 kg and 85 kg. The standard settings are a 4.8 Nm/mm in the fork and a 5.7 Nm/mm spring in the shock. So if I am over 85 kg the manual recommend a 5.0 Nm/mm in the fork and a 6.0 Nm/mm spring for the shock. At the moment I ride a 2011 350 sxf with a 5.0 Nm/mm in the fork and a 5.7 Nm/mm in the shock. My 2011 is fine with that settings but the 2013 models seem to be much stiffer from the settings. In the current motocross action magazine test from the 350 sxf they also recommend the standard springs but I am not sure how heavy that riders are.
