not much... i just got bored today and felt like doing this... its fairly easy... most of you would kno how to do this anyways
step 1: find a shocked razor fork... like the ones that came on the b2's or something like that
step 2: take out the springs and other stuff that is there
step 3: grind down the top portion where you took the springs out (the is optional though... if you can find the right size stuff just put it in there)
step 4: drill holes in the top portions where you grinded down
step 5: place your materials between the openings
step 6: bolt that stuff together and you gots a wannabe SR Fork... lol
i also took out the little spacer thing that comes on it stock... but thats if you want to use like a 110mm wheel in there
