KX 65 Output Shaft Leak

[Scooterb]

This is driving me crazy..my sons 2000 KX65 was leaking oil. I found the leak it was the outputshaft.

I have replaced the seal and O-ring then after 1 ride it is leaking again.

Any one know if this is a trait of this bike or did I miss something.

Next step is Im going to replace the seal, sleeve, and double the o-ring.

Any other ideas???

KDX's and some KTm's will leak there, if the c-s sprocket is too thin (ie, cs sprocket must maintain pressure against sleeve, else fluid will seep past...).
