Default Re: how to make an engine quieter/stealth

What I mean is that when the engine is at idle, its positively hushed. But because I use a shift kit, any time I'm moving I have the throttle near the high end, and the gearbox is under load. It doesn't seem to make a difference what speed I'm going.

Obviously wind noise makes a racket at 30+MPH, but I can handle that.

I'm also concerned about noise for safety reasons. I used to bicycle commute 100% pedal powered, and I could tell if a car is approaching from behind by just the sound of it. But with the motor going, I've been startled a few times too many. It would be really nice if I could perceive dangers and hazards more like I used to.

God knows I need it
