Re: Disguising an engine
The burlap is a bad idea.
Any screen over the motor will hamper cooling.
If not moving at a decent rate to force air through a cooling duct will be fatal.
the burlap fabric will soak up engine fumes and become a combustion point.
just like a molotov cocktail.
probly not a gud thing.
IMO, exhaust noise is first to bring unwanted attention,
second would be erratic movements in the traffic pattern.
Third might be NOT dressing as a customary bicyclist.
Fourth would be a Pnut tank.
