Now we have BVM in addition to his BMV and BMW. I've never heard either a
BMV or BVM so I'll take your word that they sputter.

LOL. I didn't even realize I did that. Interesting!

Real engines
tuned properly (excluding racing engines with aggressive cams) don't
sputter. I don't consider Harley's to sputter either. They have an
uneven cadence, but I don't consider that to be sputtering by any
definition I'm familiar with.

You don't think Harleys sputter? I know you know they have an uneven firing
cadence, due to the angle of the cylinders, but besides the uneven
bap-bap---bap-bap---bap-bap, many times they don't hit on both cylinders on
every two revolutions. I call that sputtering. Perhaps you don't.

I guess sputtering is in the eye (or ear) of the beholder?

Read the url I gave for the Webster's definition of sputtering. That is
my reference point. No, I don't think Harley's sputter given that
definition. Top Fuel dragsters sputter and at night you can see the
explosions coming out of the straight pipes.

Yes, it is in the eye of the beholder, but to say that ALL airplane
engines sputter is simply not correct by any stretch of the imagination.
