Searched the forum on this topic, but wanted additional input.

This winter I put an MSR seal kit (seals, dust seals, etc) on my forks as the stock seals were always weeping. Well, 3-4 rides into it and the right front seal began puking (left has been fine). Tried to clean it with a seal mate 3-4 times, but it continues to run out at odd times.

Anyways, very annoying, and I really don't want to buy a whole addtional MSR kit as the one seal is still good as I am sure are the dust seals. I have heard various seal options for the 06-09' yz's. I don't think just buying a single 06' OEM seal would help me out much, as it would most likely just leak like the stockers did. Do you guys recommend seals from earlier model year yz's for the 06' (03'-05' or something like that work better?), or is there an aftermarket brand seal I could only buy 1 of??

Thanks for the input men,

C

Smart Performance sells a KYB seal that I have had good luck with. These may or may not be the same as the latest seals from Yamaha, but either way, they work.

Others have suggested using seals for the 47mm fork on the CRF.

..and the right front seal began puking ...



Hi C-man
How is the bearing on the right side of the front wheel? I have a small leak on mine too and saw it too late, the play of the bearing was screwing on my seal. No the bearing is done but still just 4 drops per ride maybe but the left site dry as the desert. Does Yamaha not sell those bearing singularly?

My bearing is OK...not sure if they sell them as a single or not...you would think they would.

Put an 08' crf 450 oil seal in on the leaky right fork last night. I used the 08' seal from the honda as it was a 47mm (1mm smaller than my 48mm fork) and the 09' honda's are now 48mm fork as well. I was not sure how well the 09' honda seal would work as everything I have heard from you guys said to use the 47mm honda seal.

My question is, to anyone who has used the 47mm honda seal on their 48mm yamaha forks, how much more sticktion is there vs the stock yamaha seals?? I am sure there is bound to be more, and I have not ridden the bike yet. To fell it just compressing the forks while sitting on it it feels a little more sticky, but could be mostly my imagination. Is there a noticable difference in fork action while riding?? I myself ride mostly trail and an occasional hare scramble and would rather have the fork not leak daily vs. have it work slightly smoother.

Thanks for the input,

Update:

08' CRF seal was a little sticky feeling just after initial installation when just feeling fork action while sitting on the bike. Went on a 55 mile ride today and handling felt fine. Seal also now feels very normal when compressing forks, etc while just sitting on the bike (definately feels like the sticktion loosened up a bit). Seal seems to wipe more cleanly than the stockers or the MSR's ever did, so I'll post more later on how the CRF seal does for longevity.

I think you will be ok, but there will be more stiction. Many used the Showa seals on 06 yami forks including MXA....whoopie Doo
Now KYB has made better seals and they work just fine

I had the same problem on my 2006 yz450f and I put 04-05 rmz 250 seals in about 3 months ago and all is good. Recommended by Rob @ 4PR performance in IL.

My seals got to where they were leaking and I put a Moose racing seals in and they leaked also. I have always herd to use the OEM's in yamahas and you cant go wrong. Mine is an 06 also and I need to change the oil in my forks.

I have had crappy luck with a set of Moose seals. Leaked right away.

My suggestion is Pro X seal and wiper kit. I believe its cheaper than oem, and same exact thing. At least it has the same markings (letters/numbers) on the bottom of the seal.
