What type of oil should I be running in it? I am 140-145. I am not smooth and like to do drops??
5/15 wt?
The leg with the rebound adjustment is the leg that is supposed to get the heavier oil correct?
Also, what springs should I run?

Intrested in trades for that super 8?
how bout selling the avy alone? i could give you a fox to replace it with....
as far as the boxxer, the rebound leg of course controls the rebound, so you'd want the heavier oil in it. also the oil levels should be slightly different, i forget which one gets more though.
Wait for jamesnobrakes or jm_ to come around and help you, he is the boxxer expert.

i'd go 20wt rebound, 10 compression, then go from there, if you feel you need more rebond 30 is the max, compression doesn't seem to be ultra-effective, meaning don't expect it to get lots plusher if you use heavier compression oil, sometimes using more low speed compression damping(ajuster underneeth the compression leg) or using a slightly heavier compression oil can make it feel plusher, so don't be put off by 10wt, the boxxer orifices are huge and you have to use pretty heavy oils to make any difference, and even with all of this it will still feel "fast" and the rebound will not feel like it's working, however its "just enough" to keep from bucking you, so it will feel fast but that is the way boxxers work, and you can't really slow it down like you can a marzocchi, so don't go on an endless tuning serch, because it doesn't have a big tuning range and ajustments don't make a HUGE difference like they do in other forks.
Anyway, hope this helps, you want to switch out the oil about every month, like if you are riding a few times a week, because it gets comtaminated easily and quickly, doing this will extend the seal life and ensure good preformance.

Here is what I did to my '01 Boxxer
you are a tad lighter than I am...I'm in the 150's but setup should be similar. If you want to keep your Boxxer smooth, Just make sure you keep the dust seals clean and you should be fine. But I do recommend changing the oil at least every 6 months depending on how much you ride. Here is how mine is set up...
- I use one soft (grey) spring and one Med (Yellow). This might work for you as well, if it's too stiff, try 2 silver springs. I don't use any preload spacers.
- For oil, I use RockOil (www.rockoilusa.com). You should measure the amount in volume, 200cc in each leg. 20wt in the Rebound and 10wt in the Compression. just make sure that you cycle each upper tubes in order to completely drain the old oil.
- here is a BlackBox trick. Take the stock compression check valve out and drill 8 5/64" holes. That is 2 new holes between each of the 4 holes. Here is a pic of mine (After/Before)
it smoothes out the compression stroke. One tip on drilling the holes is to do it from the bottom, as it is easier to judge where to put them. Just match the drill size to the other holes.
- By drilling the extra holes you will increase the low-speed compression damping & rebound damping because you can use 10wt oil without spiking, & the higher oil levels will resist bottoming. I recommend leaving the high speed adjustment where it is.
- Another thing you can do to smothen your fork it take a scotch bright pad...soak it in 10wt oil and polish your stanchions with it...makes them super smooth.
- Again, when installing the new blood make sure you cycle the upper tubed 20-30 times in order to get the oil to fill the valves.
- Install the springs. Completely top out the fork! let it sit for while then install the top caps.
ok i understand everything except for "cycling". what exactly do you mean by that? like compressing and decompressing the fork?

also, what are the stock springs in the boxxer? i believe that the springs that came with mine are stock.
does anyone have like a .pdf file w/ the boxxer manual or some sort of pic with a schematic? that would help! thanks.

yeah, just like you do when you test the fork out once it's build...this will get all the oil out (when you empty it) or oil in (when you refill) in the rebound/compression assembly. Go to the Rock Shox web site and download the Boxxer Service Manual, it's extemely helpful and had many pics that will guide you through the steps.
Acadian, how many miles have you put on your boxxer with this "mod"??
I am concerned that this is more of a "psychological" improvement, rather than an actual one.

Common, say it with me Acadian; OIL SHOULD BE CHANGED AFTER 40 HOURS OF RIDING
Thats not 6 months, and that is IN the manual as I remember it(got it on my computer anyhow).

I haven't really tested it as I got injured as I was making this mod. I just rode the bike around lately and the stroke feels a lot more smoother. I've also heard from others that have made this mod that it indeed improoves the fork. TF does this for a reason...when you send your fork to them they do this exact same mod.
Why do you think this is a "psychological" improvement?
Psychological imporovments are where someone tells you something will make your fork or bike feel better, and since you "think" that it will, your mind will think that somehow it feels better, when it does not. The mind is a powerfull thing and fairly easy to influence. Take fork "tuning" for example, where techs at a shop just set up a fork according to the setup charts and weight, but when people get them back they think its 100x better, that may be an overstatement but sometimes the differences are not nearly as big as they think they are, and the setup is something they could have easily accomplished on their own, but they think its getting something magical done to it at the shop, and when they get it they thing it feels that much more special.
