I have a 2005 EC200 that has eaten two RH crank seals in less than 1 hour of run time. The bike is burning trans oil.
I replaced the inner o-ring on the crank both times. The first replacement I used the all-balls kit and the second I used an OEM seal. The seal spacer did have a small groove...
Doing a top end service on my 2005 Gas Gas EC200. Replating the Cylinder and new Wossner Piston. Wossner states the small end bearing to be different from that of an EC250/300. The dimensions of the bearings are different with the EC200 bearing being 2mm shorter (19.8mm vs 21.8mm).
The history...
