another alternative is to use a small, fine file and slightly round off the sharp edge of the shaft that cuts the seal.KTM sells a plastic cone protector or use some tape on the balancer shaft
should there be an oring where the water gallery comes out the crankcase and meets the clutch case ?
Would probably need a picture to properly understand the question but...
A o-ring is on the balancer shaft AKA The Water Pump Shaft.
When sourcing the o-ring in the parts book look at the balancer shaft diagram not the water pump diagram. Purchase a few of them as they are not easily sourced from aftermarket suppliers (your local auto parts store).
we call it the water jacket O ring.
