If anyone can help me decipher this I would greatly appreciate it. Thank you, Russ

Trying to identify #s on a CF 50 Chaly. Can anyone help? Thanks

It should be at the bottom of the frame, above the engine bolts.

Has the bike been shotblasted and resprayed? My number is hard to see/read now that I had it blasted and powder coated.

CF 50 2847840 I do not see this series of numbers on my parts manual.
Im trying to identify the year it was made.
