i got a 01 ec125 and im not sure what forks i have and they need a rebuild, well maybe not a rebuild but they need to be taken care off. the seal on the right leg has popped out halfway and oil has leaked out slowly.

any idea of what type of forks are those? will get better pictures tomorrow

They are WP43s, easy to do a seal job on. That bike looks awfully familiar, just like my nephew's old bike. Where are you located?
 
Small world, especially the GG world. You bought that bike from my brother Craig. Thats a good bike, I personally rebuilt the motor from the bottom up a few years ago and it has seen little time since. My nephew went like hell on that thing, didn't race much but when he did he was awesome. I wanted that bike for a 144 project but he wanted to sell it faster than I was ready.

Probably due for seals, sitting is the worst thing for that. I did all the suspension service on the bike too.

If you want to ride sometime let me know, I'll show you where its been.
 
oh small world hahaha
i bought the bike in excellent condition, when my brother and I went to look at it we were shocked how clean it was for a 01'.
so you basically know the whole bike in and out haha
i'd be very interested to go see what the bike has been through, i just have to get a bit better on handling it before i do that.

so here is what happened

what about a diy write up on how to replace it? do you know of any?
Thanks
 
you can get seals from a us seller - no need to buy from overseas..

the vids at rocky mountain atv are excellent. no special tools are needed, aside from snap ring pliers... there are work arounds for everything else.

what they don't mention in the vids:
make a note of where the top adjuster is, and then back off the top adjuster all the way out before you open it up. when you reinstall the rod, make sure it is all the way down in (flush). if it's not it'll not work...
 
Those cheap seals are junk. Get a good seal/wiper kit like SKF.

Its pretty gnarly up here. Get some seat time in and used to the bike first.
 
The earlier Synergy seal design requires a very specific install procedure, which the instructions did not clearly describe.

As a result the seals leaked right away. I had to buy another set after talking to Synergy seals and getting the real details on how install them correctly to prevent damage.

Bottom line - poor instructions, costly (2 sets to get it right), they have held up quite well.

Caveat - their newer designs may be different.
 
Stock WP seals are good, or SKF. Any KTM dealer should have in stock. Stay away from the cheap Moose Chineese stuff.
 
Synergy Seals

I have to give a shout out for Synergy.

Rob is an awesome guy, he has called me back on the weekend to answer questions or help with installation wisdom. Plus I think that he is riding a Gasgas now.

I used them on my KTM. The forks went through seals on a pretty regular basis, then I installed his seals and never changed them again. Plus they are pretty slick (eliminating stiction).

Give Synergy a call and see what they can do.

which seals did you use?

I recently fitted the flexible ones in my sachs forks and they involved a lot of swearing to get them in!! didn't help that the first time i got them in i realised i had forgotten to slide the dust seal onto the tube before the seal went on DOH!!

eventually got them on, but cannot comment on stiction yet since i have only managed about 2 hours on the bike since i fitted them (they felt very tight just trying to slide the tube in and out during reassembly, but smooth). getting the dust seal in place would not be possible with the forks fitted to the bike so i will not be doing any cleaning or maintenance of them unless i am servicing the forks
 
Do you guys have seal drivers or do you use some other way? I'we done a few seal jobs and I always find it kinda hard to drive the seals in, and also usually involves some, or alot of swearing :0
 
i have a home-made seal driver from some pvc plumbing pipe, but you cannot use them on the flexible synergy seal - well not the way you normally do. The hard part about the flexible seal is actually just getting it in the first part of the upper tube, after that it is not so hard
 
I've made and used my own seal drivers but the best I've used yet is the Motion Pro "ringer" seal driver. Stays locked around the fork and heavy enough to use as a slap hammer for the tight fitting seals like in the Zoke 45s.

what is the special installation procedure? i'm intrigued... are these 3 lip seals (2 inner and 1 outer??) or are they quadrile?

The flexible seals were by far the hardest I have ever installed. I don't even want to tell anyone how long the first fork leg took me. The second was considerably faster.

Once they were in they were magic, very low stction and lasted for years on my KTM. I actually just bought a set for my Gasgas.

There is a YouTube video out there to watch also.
