I got a 1977 Yamaha Chappy a wile ago for $50... and it was worth $50. After pulling the LB-50 motor apart I desided to swap it out for a E-50 to save time and money. DETROIT APACOLIPS BIKE! Nothing like 8" steel rims to take the Detroit pot holes! UPDATE: Blew out the rear tire bad a couple weeks ago, new tire, bearings, and 15 PHBG... almost a 50mph chappy! Suck it LB50 engine!
