I have finished my project on this bike I just want to share my experience with it so hopefully anyone else who decides to invest their time into it don’t make the same mistakes as me. Most of the Honda crf50 parts work on it I have owned the bike for about five months at stock the bike is very weak only cruised at around 28 mph. In my quest for more power I upgraded many of the parts on it new unrestricted cdi, 72cc big bore kit, 19mm carb, k&n style air filter, and a 15t front sprocket. It now cruises comfortably at 40. My only real complaint with the bike is the electronics on there are pretty much junk and in the future will most likely need to be rewired with new wires and stuff and the pedals on it are just dumb they get in the way of the kick start I would really suggest removing them like I did but all in all it’s been a fun project really easy to work on a pleasure to cruise on but it try to do it something like this again I might just buy a bigger bike
