This is a Huffy Karaoke, 66cc chrome slant head, 41 tooth sprocket. Coaster brake omitted, front caliper brake added, rear caliper soon to come. Rear fender removed due to chain rub, had some difficulty starting, and it idles way too high, I'll get the tweaks eventually. Gotta endure the break in period. There are next to no vibs on this bike! I'm amazed. Very quiet, however, I'll need to make some more clutch adjustments. Coming along nicely though!
