How much is TOO much?

[Striker1423]

Question time.

It seems no matter how meticulous I try to be I can never assemble a motor without a bit of dust getting in it. My garage is not clean, but neither are any of the motorcycle shops I've ever been in where people service a plethora of bikes... 2 strokes included. Vertical scratches on pistons and in cylinders, a pattern? Is it just me? Are we really expecting to see pristine pistons every single top end refresh? How do some people manage this seemingly miraculous feat, but others (myself) can never seem to make it happen?  It's not like I'm pouring dirt in the motor ffs.

More is better, too much is just right. That's what my father always says.

The only pristine top ends I've ever seen ran for like an hour.

 Been my experience that no matter how much you clean a cylinder after a bore and hone that there always is something left hiding. Kinda like cleaning guns.. always something hanging around.
