Blast from the past. This is the bike we rode when I was a kid. 30 years later scooped it out of the barn and rebuilt the LB50 with a big bore kit from Polini. Rode it for a summer and decided to do a Lifan 125cc with a manual 4 speed swap.

Finished up the foot brake last night. Took a lot of fitting and testing but got it working right. Also swapped out the main to a 105 and got the carb tuned. She is running like a champ! Check out the new photos.

Mounted the rear tail lights and painted then wrapped the exhaust. Pics added.

More pics of current state. Oil cooler added, new rear shocks. Now to pretty up the frame and start the lighting. Need to add rear lights and front turn signals.
