yeah CRM called me a BSer and maybe others think that too till they actually try a torque pipe and get blown away with its performance.
My Dellorto 14mm is only used with my 48cc piston port intake engine. It has 4 holes, and from bottom to top have these sizes: .7mm, .52mm, .8mm, 1mm
The engine has extended intake and standard extended exhaust, 140psi compression, slight porting, and Jaguar CDI (using a KX high voltage coil). oh and the crank is stuffed although I wish it wasn't because non-stuffed is better for low rpm power and the 48cc needs all the help it can get in that area.
yeah you are right about noise being a warning signal: "get the hell out of my way or get run over!" or something like that. ha!
If you are super quiet they pull out in front of you because they expect your speed to be that of a bicycle. I just personally hate noise pollution. Some happy medium has to be achieved.
