i have posted theese questions on the tech talk, but there was said, here can i get more response.

so:

i have looked around, to make my boxxer race perform better.
i know, i have 2 options to do this: blackbox kit and mojo boxxer kit.
so the question: which one is the better? or is better one of them than the other?
what exactly is inside of a mojo kit? (you could be more specific than "2 cl oil" or like this.) - pics, drawings, anything that can help me, is welcomed.

if this topic was here discussed, so pls post the link.

another question, not boxxer:
in a "horst-link" suspension design are the distances (or the angles, or both) of the bearings and the center of the rearhub's axle patented, or any frame, thet uses 4-bar linkage, where one of the bearings is at the chainstay (not kona-like at the seatstay) are "horst-link"?

thanks for help me.

ill be to the point because these topics have been discussed several times already

if you want a better performing fork then:

blackbox option -> no
your fork does not have a compression damper inside, fiddling with it the way it is now can -at most- give you better rebound performance, but i guess thats not a problem now.

mojo kit -> good idea if you like the boxxer platform (jargon for external structure, uppers, lowers and crowns). it will replace everything on the inside of your fork with a closed, fox-ish, cartridge on one side and a spring in the other. search for opinions.

option number 3 would be to upgrade your fork to boxxer team specs, should be about as expensive or maybe a bit less than the mojo route. this means installing a compresson damper in your fork, then youll have a fork thats in essence the same as the new 04 team boxxer. search for "bremen labs boxxer".

if i choose the mojo (it's a closed patron - could it be blown?) then what would do the lubrication of the seas? grease?

grease or oil just like you have going on in your boxxer race dummy rod side (only a few cc`s of oil in there you know.)

There will in the next few months be another company making a fix for the boxxer. I beleive they are still working on it. So if you can wait till the beinging of Aug, there might another option.

just another question:
see the future, is it worth, to invest that ammount of money in a year 2003 fork, or i should leave it as it is (and get used to it), and buy a new manitou sherman slider plus, or even wait 'til the new boxxer with the motion control arrives?

I would just wait and be patent cause what I have heard it will be similar to the 05 boxxer feel.

Luc, I'm sure you're already in the know, bot for those of you asking, the only big difference between the '05 and '04 Boxxers is the addition of a U-Turn style travel adjustment. I believe (but don't quote me on this) it's externally adjustable from 5 (or 6) to 8 inches of loving.

And to those of you bagging on the Boxxer, it ain't 1999 any more, get with the times. The '04 Boxxer with new rebound base valve assembly and Blackbox compression unit is amazing. No leaks, unbelievably plush, plenty stiff and it's light.

I'd take it (oh wait - I have) over the 888 for racing any day!

Oh I am not bagging on them but I don't think your questioning me any way. I am a fan with some modifications to them and then there the best fork out there.
Luc if you have felt and 04 you have felt the 05 just that they will be adding some things like the u turn, external adjustments but that won't change the feel. The only thing I see and here a lot of people complaining (that like them) is that the rebound is off, like to much or to little and not enough adjustment. These are good forks but with some up grades, no not a mojo, they can be the best.

TIME OUT for you!!!

I could make a list of all the bikes I've "pushed' on and didn't think felt great in the "push test"....im not going to, it would be equally rediculous.l

oh man, I bet you've been waiting for the day you could call me out on this one?

Actually one of them I actually "tried"...like rode on a acutally dirt trail with holes and rocks...

And no I am not thinking of push internals, but another company that will soon be releasing.

dude..not that there is anything wrong with my Boxxer, but you know me. I'm always willing to try new stuff!

first I dunno if we are talking about the same thing? But if the price is right and the improvements are true, I might give it a "try". Heck I have enough parts to build a separate Boxxer :p

Ok, so you tried it out on the trail downhilling, don't say you decided that you didn't like it because you "pushed down on it", I'd hope that ANYONE on this site would be called out for saying such a thing, me included. It's a rediculous statement.

If push makes this upgrade as rumored, it will be an interesting dillema for those that claim that cartridge dampers would not be an improvement for the fork....

If executed correctly (as push has shown they can) it is a no-brainer. Dual stage pistons, low and high speed blowoffs, anti-bottoming cones, etc. Yes, cartridges have a lot more to offer.

Interesting note on Boxxer internals... Carters Boxxer has an air valve at the top of one leg, and two adjuster knobs ALA a fox RLC on the other leg...

i'm back with my questions ;)

recently i changed my '03 race to an '02 electric red.

now i can feel, what means "boxxer-feeling"
my race wasn't a real boxxer, just a similar something.

now: is it worth, to buy the blackbox kit for this (electric red) one, or this upgrade are for the '03-'04 team/wc modells?

I'm sure luc can answer this better but,

you might be able to put the 2004 internals into your 2002. Some 2002 Boxxers are straight wall and some are butted tubing. I know it will not work on the butted tubing versions.

It might be cheaper to sell the 2002 and buy a used 2003 black boxxed boxxer when the 2005's come out. I know people will want the Ti sprung 8" World cup once they are out. There might be a flood of 2003 and 2004 boxxers on ebay.

Like Chris mentioned, some early 02 Boxxers had Tapered upper tubes - you can tell this by opening the fork and verifying if it uses glide rings at the top of each damper assembly. Did you buy a new fork or you just got different castings? Here are some tips/advice.

- The BlackBox upgrade is only for 2003 Boxxers.

- One thing you should do is verify your stock compression check valve to see how many oil flow holes it has? If it only has 4, I suggest drilling 8 5/64" holes. That is 2 new holes between each of the 4 holes. Here is a pic of mine (After/Before), which I did on my 01 Boxxer

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.

- For oil, I use RockOil. You should measure the amount from the top of the stanchions when fully compressed instead of measuring by volume.

- 01 and 02 Boxxers take different amounts. Straight walls use 110-120mm height or you will lose travel (02 forks), Taper wall use 90-100mm (01 forks). 10wt in Compression, 20wt in Rebound.

- 03 Boxxers take 115mm in both legs. 10wt in Compression. For rebound, you can use 5wt, which would help if you are using stiffer springs. Or you can just stick with the 2.5wt for the lighter, smoother action. This is what I run in mine.

- 03 castings will ONLY work with 03-04 forks.

- The older castings will work up through 02.

ohh, 'bit too much so many information for the first time, but thanks for the answering!

my boxxer is a late '02 model with straight tubes. i'we bought it used. i use 20 wt motorex oil in the rebound leg and 10 wt in the compression, but in the closed rebound damping setting it comes back a bit fast. i measure the ammount of oil in mm, not in ml. it is now on the basis setup. more oil would it make slower or just the bottoming resistance changes?

someone told me to use 30 wt oil in the rebound leg, but i can't find 30 wt oil. (it is possible there aren't 30 wt oil out there)

those drillings could help my problem, or the fork gets even faster?

there is one fix for you problem 1st you pull you stantions out of you lowers 2nd you shove an M80 in each side of the lowers 3rd you light the fuses 4th you run 5th you trow what remains of the fork in the trash and 5th you buy a zocky or manitue
