Car Venetian Blinds old school but effective as can be closed during winter for headlights from car behind blinding

I missed last week's Friday night Jams but I built my ride to work. It's a 85cc "dominator" 2 stroke motor, so far it has went 35 mph with plenty of room left with a 240 pound man going slightly uphill once I break it in and finish tuning it I believe it will go well over 40mph with 200 dollars in engine and parts on a 60 dollar bike.
