sockethead commented on Paul Olesen's blog entry in Moto MindAh, the joys of 4-strokes! Everything ingested is confined to above the piston rings - 'the cylinder bore showed no signs of excessive wear or damage and it measured well within the service limits' - just how it's designed to be! Imagine if this had been a 2-stroke! Anybody remember carb trumpets with tea-strainers over the end?!
