hey - this leads me to a moped question that will surely get us kicked out of this section. Just got a sweet CEV bullet moped headlight with a hole for a 2 1/2 inch speedo. thinking about putting it on my 400F with a drag specialties speedo in it. that is, if I could get a decent (roughly) 4 1/2" 12 V hi/lo headlamp to fill it. where do you get your vintage moped parts from?
