Hi! My friend just got a manual for NC-NA 50 ,and it is awesome.I think it's over 120 pgs.,and pictures galore.The year of your bike should be stamped in the I.D. plate,my friend Henry says.He got his manual from E-bay but go to the site `Expressly Mopeds' thru searching the links and you can get one there ,I think.You really have to have a shop manual if you want to keep the bike.BYE!
