Took the Wr for a blast down to the shop this morning. Got back and noticed oil pissing out of the output shaft seal. Pulled the sprocket cover off to find that I'd somehow forgotten to bend over the lock tab last time I had the front sprocket off, which was about 500km ago. This allowed the sleeve to move outwards causing the oil leak. Replaced the seal as a precaution. Lucky it didnt stuff the spline and the gearbox. On a better note I bought a Honda (ssshh dont tell anyone!) hourmeter the other day. It has a tach feature built in which I thought was pretty trick. They are probably common place in the US of A, but this is the first one I've seen in Oz.
