@vlad, so in your learned opinion... does this piston look "fecked, like it has been thrashed with poor maintenance"?
The piston in all these pictures is the same one! it's the piston from 'Wizzwanger's Wave which had done 85,000 Km of moderate riding, not thrashed, and had the oil changed every 3,000 - 4,000 Km.vlad wrote:I would imagine a new 4 Stroke will do 25-30 k before rings are worn if its been looked after.
The piston wasn't 'fecked', it just needed cleaning with a brass brush to remove the burnt oil stains and mild carbon build up around the crown and in the ring lands. The cylinder was hone just to break the glaze. Engine now burns no oil.
