Fork seals

Went on a trail ride last weekend. Went into garage yesterday and found pool of oil under right fork. I've had seals weep before and lower fork be wet before but never had oil on floor. Maybe 4oz of oil on floor. Removed dust seal and repeatedly cleaned with feeler gauge until it stopped leaking when compressing. Didn't leak on the ride, forks felt good and no leak checking today.

Taking Shane Watts weekend class May 12. I'd hate to have the forks barf mid class but I have been known to worry too much. Replace seals or go drink a beer?

I would replace it but that is just me. Shane is going to work you and the bike hard and you want it 100%

At a minimum pull the fork and change the fork oil to the proper amount since you lost so much. This is assuming you haven't already done that.

Since it did not leak after your last ride you may be OK. Assuming there is any oil left in there.

I'd vote for changing the seals. It's a very easy job, and you have plenty of time. Mine leaked, but not enough to foul the brake pads. When you have them apart, check the wear on the bushings. If they are showing signs of wear, it's probably time to change them as well, and they can contribute to leaking seals as well. I watched the Rocky Mountain ATV Youtube video, and there is some good info in the Slavens video where he shows how to pump out the air. Simple 10cc syringe and a marked pice of vinyl tubing to set the air gap. It may be sacrilege, but my forks were super harsh, and the clickers were set all the way out, so I also took the opportunity to try 2.5W oil, and they are awesome now.

Thanks for the replies. The thought that I had no oil had occurred to me but I think capacity is more than I lost.

Thanks for the videos links. Bike has 4500 miles so I'll replace them. I'll check the bushings for slop.

I'd heard that it was best to stick to OEM, that the aftermarket seals were problematic.

I went aftermarket on my old 600 LC4, and the leg that wasn't leaking before the chainge, was leaking worse than the origanal leak.

I had also heard about aftermarket KTM seals being probematic, but used them anyway because I have never had problems with them on any of my Jap bikes...

So is it a WP thing, or are all aftermarkt seals for all brands of forks suposed to be problematic?

Oh and thanks everyone for the replies about the rear brake res placement...

All sorted now.

You can check KTMTalk, but I'm pretty sure SKF seals are the ones to have. Again, when looking into fork stuff, I came upon this Slavens video on seals. I bought seals from the KTM dealer, and I'm pretty sure they are SKF.

Lots of options it seems:

1) Fiche for my 2007 450EXC says: "R14013 REPAIR-KIT EXC FRONT FORK06/07 $115.49". That's seals and bushings for both forks according to KTMTalk.

2) R14020 is the skf seal (low stiction) kit for the SXS forks. Mentions working on 07 w/ mods but maybe not RFS. I'll have to ask Munn. http://ktmtalk.com/index.php?showtopic=410085

3) Synergy Seals sells a kit with 48mm Dust Wiper, 48mm fork seals wth lower guide P-Bushing-48 and 48mm Rigid Dual Lip oil Seals. $84

4) SKF seals and KYB bushings are available aftermarket but I could only find mention of calling a licensed suspension tuner such as Trailticks/Slavens.

OK I need opinions here...

I need a new piston for my 525, and it has a 97mm bore.

I have just been doing eBay searches for pistons because they are a hell of a lot cheaper than getting them locally (I was quoted over $300 for a 95mm Pro X, I could get one of eBay for half that including postage).

Now from what I have seen I can get a Pro X or a Wiseco for under $200 delivered, but I have been turned of ProX buy the cheep price, but I have started to hear not very nice things about Wiseco lately (mainly just being concerns because its a forged piston), so I'm getting a bit concerned.

Any opinions on the Wiseco or ProX pistons?

Or anyone have any suggestions of anyone who will ship to Australia that I should look at for a Wossner or something (that is if Wossner make a 97mm piston for the 525)?


Or should I just ask in the main forum so I don't start a forged vs cast shit fight?

Agreed, fantastic deal considering what's all included.

In addition to being low friction the SKF seals are also reported to last much longer.

I'd get the Wossner or a CP, very good feedback on both of those.

For the Wossner contact Dave Hopkins aka DJH (http://www.djhcyclesport.com/), for the CP contact Travis at Thumper Racing (http://www.thumperracing.net/). Both ship internationally, are great to deal with and hugely knowledgeable about the RFS so you can be sure you get the right parts.
