Racing station would be a good call... you can lighten the spring by going super aggressive on the valving..

I personally am into heavier springs with light pre-load and just enough dampening to control the spring.
I am not into hydro-locking the valving...or coming anywhere near that...it is not as consistent with temperature variations...and is harder on the internals.

Brockstar racing has a good setup.

Put them on a couple of my builds.

Cisco, I have the same bike. Another option is to add some fork oil and or Schrader valves on each leg to add some air. I did both on mine and although I'm about 30lbs lighter I never bottomed that I recall all season. Prior to the extra oil and only about 5psi of air it bottomed easily. If you search you should find couple posts about adding oil and the Schrader valves. There is limited space for the valves, you have to drill and tap the fork cap for the valve so smaller is better. I think I posted a size and part number in a post last year or so. Also, I got the idea from catsledman's post so you could search his posts also. Fwiw.

i am a mecanic and did the spring job before on my ktm .
i also live in canada / quebec and was looking for spring size for my ride and weight . i buy my spring from stadium in montreal and it simple and cheap . stadium is a motocross shop and i figure they do not know much about snowbike .
my idee was to run valving more close as possible ( 12 to 8 click ) and put the biggest spring before grinding out the fork tube . also that ktm may be living the rest off is life as a snowbike . looking to have ktm 300 for sumer time .

I'm not sure exactly how the spring rates translate between the newer explor forks and the older ones, but on my 2014 500 with 48mm OC forks, I ran .62kg/mm springs and they were pretty much perfect. I'm about 220 in riding gear. The forks were way too soft before with stock springs and bottomed all the time. With the .62 they rarely bottomed, and bike seemed to work better with the front end sitting higher up in the stroke. This is with stock valving, oil level, and clicker settings. I did have to grind down the fins on the black plastic spring guide a little bit so that they would fit inside the .62 springs, but that was pretty minor.
