Gotowo, I have had the suspension on my DRZ done by Techniks. Pretty much the work Brad has recommended above. Springs front and rear to suit my weight. T-valve in front and re-valve the rear. I can tell you it is the best money you will spend on the DRZ.
Mine now actually feels softer over the small stuff even though it has heavier springs but it now takes big hits and landings from jumps (I’m no supercross rider, I’m talking erosion mounds) without harsh bottoming.
The bike generally tracks better over rough ground and is much easier to get into corners. Before the front would push bad. I have also raised the fork in the triple clamp 5mm to aid with turning in.
Another thing to note is at first I only got the forks done. I think a few others on here have had the front done and not the rear. This was an improvment but getting the rear done to suit made the bike that much better.
Mate I have no affiliation with Tekniks and I pay full price for there service, I’m also lucky enough to only live 10mins from there workshop. This is the second bike I have done by them, they worked similar wonders on my old XR280. I’m sure there are other great suspension tuners out there but Tekniks have my vote.
