Dirt Tricks testing has determined that the OEM dome washer is made of mildly heat treated material. When that component is installed under a tightened counter-shaft bolt, it is taken well beyond it's "yield" or "elastic" limit and permanently deforms. In that condition in cannot maintain the thrust pressure necessary to keep the sprocket tight to the splined shaft. That leads to two different failures. First, as described above, the O-ring is allowed enough clearance that it begins seeping. Secondly, the backlash between the splined shaft and sprocket is allowed to more freely pound in each direction, as the torque of power verses compression reverses itself. Dirt Tricks has developed a tool steel, heat-treated dome washer that develops two to three times the pre-load force without reaching it's elastic limit and without over-stressing the mating components. This solves O-ring leakage as well as extending the life of both the counter-shaft and sprocket splines. A counter-shaft replacement alone, with labor costs in excess of $700. If you plan to keep your KTM four-stroke for many seasons this product is well worth the investment.
