As an aside, my 1977 Moto Guzzi Le Mans was delivered stock with velocity
stacks.
I rode it across the Nullabor (Australia) in 1978 when there was still a few
hundred
miles of dirt left unpaved. I did not replace the rings until 60,000 miles.
After that
it was mostly paved roads. Replaced cast-iron liners, pistons and rings at
110,000 miles,
and rings and pistons at 150,000 miles. No filters at any time. I
attribute increasing
traffic (and shorter trips) through the years to the apparent increase in
wear rate.
