A customer told me today he heard that the A stamped on top of a Sachs piston means top of the line, a D on top means industrial grade...What a CROCK...Maybe we should start a thread with all these internet MYTHS listed for newbies..We ALL know the old timers don't perpetuate these things, don't we ?
I have no clue about the Sachs pistons but many (not necessarily 2 stroke) pistons have numbers or letters stamped on them to denote size / bore fit / tolerance, etc. As far as the Sachs piston, if it were true, I would think that industrial grade would be top of the line!
