After replacing main engine seal and rebuilding water pump my bike is now not leaking but consuming oil at the rate ~0.5qt in less than 300 miles.
I have a little blue smoke on start but not much - especially if the oil level is below the center dot.
Always park on center stand.
So this seems to be either valve seams leaking or piston rings worn right?
Related to valve seams - anyone used VITON valve seals
