Tough crowd. Mr. Cookie is getting a thrashing. Jack Straw is already a rock star(racing Ducatis, Guitars, luthier), and he even uses Italian-agita. I am impressed.
But this agita is logical vs. emotional brain. Cookie is using the logical side of his brain- Why spend all that money and time on modification when for about the same money spent on these mods you could probably find a used 600cc Jap sportbike that would trounce any modified RE 650 in every way? Logical brain. But most of us use our emotional brain, which sometimes gets us in trouble. Ask all of us divorcees about that.
But emotionally when you start up that machine that you just successfully modified, and feel that extra speed or performance, there is nothing like that charge and satisfaction. Hey, maybe some even get they're rocks off and smoke a cigarette, I don't know.
I may get thrashed for playing psychologist!
