a little update, after calling 1977 mopeds for about 3 hours today with no answer (must be busy) i finally got through. i talked to a guy named josh, told him the story and he said he'd get a new sprocket in the mail to me and contact ups and get the whole thing straightened out. so hopefully, hopefully, i should have a new sprocket in another week. so far id say the guys at 1977 are A-OK.
