After riding a track the other day for the first time I noticed the forks on my Husa were blowing right through the stroke, more or less, and bottoming...not hard but hard enough for my puny airs!
I pulled the forks off this morning, removed the spring, removed the cartridge, emptied the oil...got about 500ml dumped out and maybe another 50-100ml on the bench & rag from the cartridge. The manual said I should see about 750ml, is this right? If so, I was down on fluid some to begin with.
The previous owner had cut the springs down about 1 1/2" and replaced with PVC shim of about 1 1/4" . I have the stock springs that he gave me too, that's how I know how much was cut down, the stock ones are 1 1/2" longer. I am wondering if this isn't adding to the harshness some? I am considering putting the stockers back in and maybe 20mm of preload shim. I am 205 lbs. now (down from 245!) and raising the oil height to 120-130 mm, stock is 150mm. Mostly riding trails, and some jumping, nothing huge....yet.
Also, if I am changing to Mobil 1 ATF, do I need to totally disassemble the cartridge and clean it before I refill with the new? Or will the little residule fork oil mix okay with the synthetic? This is my first time tearing into forks so I didn't want to get too carried away just yet. :eek:
