Fork seals

[Jens Eskildsen]

I think his shock was in a bad state, perhaps its lost some of the oil or gas, thus lacking much of the damping. Or it could just be old and worn out. A new stock one would probably be a big upgrade. Setting the sag should tell if the shock is bad or not.

What would you go for in terms of seals and oil if the forks are abused by wheelies often?
Thicker oil?

[Irongamer727]

Would you buy OEM seals and buy oil separately?

@irongamer727 I went for Athena oil seals on my RS.

Really you want to ensure that none of the bushes are excessively worn.

[Irongamer727]

@calum What bushes?

[finnerz89]

@irongamer727 there's guide bushes inside the forks. The Yamaha workshop manual says to replace them every time you do the seals. No need, but you definitely need to check them. If they're worn your fork stanchions will have too much lateral movement and it will knacker your new seals real fast.

[Irongamer727]

@finnerz89 alright. Does that mean stiffer forks will prolong the life of the seals?

[finnerz89]

@irongamer727 no, but having good guide bushes will lol.
It's not about the up and down movement it's whether there's any free play from side to side

[Irongamer727]

@finnerz89 alright. Do you know if the Wr125x and the Dt125x share the same forks?

[Irongamer727]

Is these the bushes?

@irongamer727 not a clue, they look very similar. Maybe check fowlers, they might have the same part number?

[Calum]

@irongamer727 That looks like them

[Irongamer727]

@calum where would you buy seals and oil?

[Calum]

@irongamer727 Try PJME
