Richard's 2014 WR450F lowering and spring for 130 pound rider

I got my yamalink today thanks for the fast shipment. I am a smaller 130lb rider with a 2014 wr450 do you think I should re-spring? The directions are clear for 160lb and up but I am not sure about being 30lbs less factor. Stock spring seems heavy enough even with the 10% leverage increase. Could you clarify?

At 130 pounds I would stick with the stock spring. But reset sag at 100mm and if that is too soft set it at 96mm. Then follow instructions for the high-speed compression and rebound fine tuning of the rear shock. Then raise the fork tubes UP a few millimeters based on where your final rear sag setting is.
