Motobecane Build

This is the long, but fun, process of getting a vintage moped that never got to live its life to living its fastest and most fun life it can!

On January 11th, 2022 I got some even higher performance parts on the 40TL. The 40T had 2 different models (40TS and 40TL) and I found this one is a TL, the higher priced model which had a speedometer, chrome fenders, and fork lock. Added an RGB exhaust pipe with a carbon-fiber baffle, a 21 PHBG, a high compression Parma head, and an ER3 variator.

The whole setup has: 12V CDI ignition, ER3 variator (with AX30 belt,) 70cc Airsal cylinder, high compression Parma head, 21 PHBG carburetor, RGB exhaust pipe, and 11/56 gearing. It’s pretty quick!

Here is the 40t as of August 8th. I replaced the exhaust pipe with a fully de-restricted stock pipe for more performance, and swapped a 70cc Airsal on it instead of the 50cc Airsal.

Ahhhh, nothing makes me happier than hearing all the parts I need are already in stock. It's gonna be a sick bike. 12v CDI, Dellorto 15.15 SHA, new intake, cables, handgrips, seals, bearings, and gaskets. So excited to do this build

Looking for new tubes for my tire and what size they are for the Motobecane. Keeping the original Michelin tires that are in amazing shape and have lots of tread left

Here's a picture of the spark plug, I wasn't kidding it was original

Got the engine taken off of the Motobecane and is ready for rebuild. Parts are all in at Detroit Moped Works. Got the Moby all waxed and cleaned and it looks amazing. Also got the tank de-ruster in.

When I laid my eyes on this 1977 Motobecane 40t I knew I had to have it. It's all original. Even down to the spark plug.

It has sat since 1985, untouched. With the dealership tags still on it, and it only having 95.3 miles, and one owner, I knew that I needed to save it and give it a 2nd life. It's getting a full engine rebuild with new bearings, seals, gaskets, 15/15 SHA carburetor, 15mm intake, and a 12v CDI ignition. I'm also adding a variator to it, which was an option on the Motobecanes but costed extra money. I know it will be a fun build and I may run into some issues, but if I can get it running half as good as it looks, I'll be happy.

(In case you were wondering, I bought it from a guy named Michael W. Cornstubble, the original owner's nephew who inherited it and sold it immediately. So, it's still a one owner bike.)
