Do you make a 2012 WR450F YamaLink lowering link?

Do you have the Yamalink for WR450F 2012? My weight is about 77kg (170 pounds). Do I need to change the spring or it’s just about to re-set the Sag? How can I pay you? Pay pal or trough website?

The 2012 WR450F is on our website HERE and so is the shipping information HERE and sag information can be found HERE.
