This is my first motorbicycle. I have been building choppers and bobbers since my teens. From dirt to street conversions, and puny *** commuters, to knuckles, pans, vincents, BSA's, and triumphs. Not to mention, the legendary Norton. I sorta like loud. I do be careful of my neighbors. Plus, i am a huge fan of under the radar.
All that aside, im a small human heavier than you(about a 130 lbs gap.) I have a couple gearing options, but my goal is city traffic speeds, (30-40 mph), not stinking of exhaust, and of course, aesthetics. I have a specific idea of what my finished bike should do, look like, perform as, and behaviors i can tolerate. Of course i have expectations, but this platform is new to me, so i have no frame of reference.
Until i know, im just guessing and extrapolating. I gather information. Try stuff out. Try to make it look cool. Your exhaust looks cool.
