Re: Need Help
no, i'm speaking only from my own experience with a stock (non-catalytic) (rounded both ends) muffler - I'm saying that exhaust noise is not an overwhelming factor in the overall noise of the engine as a whole.
Damping as in damping the gearbox cover, is a glue and rubber and leather and cork kind of affair, to stop sympathetic vibration of the cover
to stop the cover from acting like a guitar soundboard - the gears inside the gearcase make a devil of a racket.
If you loved exhaust noise you might be disappointed with these motors - it's pretty well drowned out by other motor noise in practice...
if any other guys disagree I'd be glad for them to jump in to correct my view in line with their experience.
