never done it with pushy forks but it must be pretty easy.. just undo the caps, pour it out and chuck in some new shit?? the oil hight is measured with the springs removed and the forks fully compressed isnt it?

7.5W is kinda light. Might explain the ultra-quick movement of the fork. Says a lot for the valving though because I almost never bottom them...

They're not too hard to do yourself. I'd only go to a shop if you needed specialist tools or just don't want to have to worry about it...

Fair enough, I was lucky, we had some ATF sitting in the shed, and the oil I was looking at from RS was going to cost a mint.

height is easy enough to guess chewy just take springs out push the fork right down and fill to about an inch below the top .. don't forget to wait a bit and pump them up and down so the oil can move around

Yeah, still haven't done the mods to mine yet, just to keep everyone updated.

Turns out you need a specialist tool to take the bottom bolts out of the forks, a marzocchi-only-super-narrow-socket-fitting for fuck sake. No they couldnt just put a normal allen head bolt in there, or even a normal bolt that you could access with a normal socket, they have to put a goddamn recessed bolt that fits in the fork with such tight tolerances you need a specialist tool to access it.

MARZOCCHI! READ THIS AND KNOW THAT YOU ARE ALL ARSECLOWNS!

*EDIT* - I did however manage to change the stock oil out for some 12ish weight (my LBS' 'secret pro blend' apparently) oil and the improvement is massive, I highly reccommend doing this if the forks are bit pogo-ish as it improves the rebound dampening out of sight.

I'll still do it, but I've got to wait for the tool to turn up at my LBS. I swear as soon as I have this stupid bolt I'm going to go to Brisbane Bolt Supplies and getting an allen head bolt to replace it.

Okly dokly. I was gonna pull my DJ3s down tonight but not if you need a spesh tool. That's a bit rude. Screw it. Might change the oil though, I've got some 10W & 15W Motul lying around that should make a difference.

I have found a socket that fit but it was in Bunning's personal set so i could only borrow/hire it. I am still looking for one that fits... What you need it a 1/4" drive so that it is nice and narrow, in 12mm. I have tried some crap ones from Super cheap auto but they suck ass.. i am still on the hunt... Anyone know a place i can buy high-quality sockets like Snap-on and stuff like that??

If it's not a high torque application just do what me and dad always do, get a cheap socket and bung it on the angle grinder till it's thin enough to fit, we have a whole bunch of "custom" sockets, just be careful if you're using them under a lot of load because they can be weak if you've ground a lot off them.
