i bought an 06 yz450 last january and love it. however, since i am morbidly obese and the suspension is finally broke-in, i felt that it was time to upgrade to some heavy duty truck springs (at least). :grin: my question is this: is it possible to change the fork springs without having to remove/replace the oil and oil seals? on my 99 yz400 (the older style forks) i used to be able to do it no problem. i had acquired all the special little tools of the trade and all that, but now it seems i need to go buy some more tools. i already bought a motion-pro "fork cap wrench", but it doesn't fit. neat-o. so i want to know who makes a fork cap wrench that WILL work, and what other tools will i need (if any). i'd like to be able to rebuild my own forks completely (i used to be able to with the older forks). what other tools are absolutely necessary? anyways, thanks in advance.
