You're welcome KIP,Thanks for the kind words. I'm doing this build (my first) over the course of the winter and just taking my time. I have a ways to go before I can fire up the engine and find out how it sounds. I did take a short pedal powered ride a few days ago and it feels nice. I look forward to making an exciting post about my first powered ride. Probably in a few more weeks. The sound is one of things I am most curious about myself as well!
Various members of the forum have called the sound "a pissed off chain saw"......"bees in a can"...."blender set on puree"...LOL !
