It's a piece of cake.
195# with gear, or is that just you?
Probably in the .42kg/mm range.
You'll need to make a spring holder. The spring needs to be held below the jam nut so you can get a wrench on the nut. It's as simple as a slot cut into a piece of sheet metal. You can use a slightly smaller wrench to do the trick, too. You'll probably have to hold onto that, though.
There is a washer that is crimped to the end of the oem spring. Make sure you it comes out with both springs. Crimp it good on the new springs before you install 'em.
Remember to loosen the top cap while the fork is still in the triple clamp. Much easier than trying to get it off when the fork is out.
The preload on the oem spring is ridiculous. Make one yourself out of schedule40 1" PVC pipe. You'll probably get a length of it with your springs.
Have fun!!
