If you do have the suspension shortened, have it resprung and re-valved to suit you.

And yes, as William1 noted, non-stocksuspension links do affect linkage ratios....some for the better, some for the worse, depending on whether they have an increased or decreased leverage ratio and where the pivot locations are.
Feel free to post more questions on TT or email me direct for additional info.

Often, if you need more than a inch, then shortening the shock is the right thing to do. But if say, you need to lower the seat height 1.5" and can thin the seat .5" and using a 1" link, you will probably be ok and it certainly is a lot less expensive.

The forks are easy to add a spacer in. Just get a machinist or a hole saw and cut some delron. for my daughters bike i used a 1 inch thich piece of delron and a hole saw (probably about a 1 inch). I then took the plug that was in the hole saw and drilled out the center to the diameter of the rod plus a few millimeters so it would slide freely. I used 2- one inch spacers in each fork.
I pulled the cartridge damper apart and put the spacers on the rod. That way the rod cannot extend the full length. IE: it is now 2 inches shorter.
Add 3 spacers if you want it more.
BUT dont add more spacers than the rear is lowered. IE: if you buy a 2 inch lowering link, only lower the front 2 inches. You want to maintain the correct angles for the steering geometry.
I did not use a lowering link. I had a race tech suspension guy put a spacer in the shock when he changed the oil. again, you can build a spacer from Delron. But the measurment is a little tricky. You need to meausre the length of the shock when it is fully extended, and then compress the rear by 2" or whatever, and measure the lenght of the shock again. it will probably only be about an 11mm spacer that is needed in the shock to get the 2 inches in the rear. DONT USE the 11mm as the number. measure your own. 11mm was the lenght for my KTM and was just an example.
I also am 5'7" and I only lowered my KTM 1.5 inches to fill comfortable. I cannot flat foot with 2 feet though; only one. 1.5 inches also maintains good clearance for the rocks and roots. and still feels comfortable for Dual Sporting.
