Hi everyone new here to moped army and mopeds in general. i recently purchased a 79 motobecane, supposedly with a 70cc kit. it rips pretty well so i do thick its got one. I've been struggling trying to find info on what kind of kit it is. it does say autotec and some serial numbers (3924184) on the head but I'm not finding anything on google. do you know anythings about these. i want to get a better exhaust, the guy i purchased it from rigged a cheap pipe and bugger welded a header. any suggestions on a pipe, are these heads any good?
Thanks for any info and help
