5 of 5 Super cases! Ima buy more. Tuesday, January 2, 2024
taco eater : Heffy from CT  
Transfers are big and almost match right up with a Doppler kit. Has a Seemingly restrictive little ridge in the transfers that I don't know what its for, you might wanna hit it with a dremel. Also the seals that come with it are way too tight your gonna wanna get some viton or other seals with it. Thassit.

5 of 5 Holes Tuesday, January 2, 2024
taco eater : Ethan Heidt from Nashville, TN United States  
It's weird that the threaded holes that are normally for the stator plate are also on the variator side, it's not a problem they can be sealed up, it just confused me at first

5 of 5 perfect platform for your gr1 racer! Tuesday, January 2, 2024
taco eater : terry dean cain from san francisco, i think  
50cc air cooled frenchies is the way to go. this is your best bet for building a bike on a budget, and with a little porting plus the 19mm carb size limit, these stock cases are perfect!

5 of 5 AV10 from now on... Tuesday, January 2, 2024
taco eater : Max Johnson from New Bedford , MA United States  
Purchased this for a 74cc build, these cases line up perfectly with https://www.treatland.tv/motobecane-av10-airsal-47mm-kit-BRIDGED-exhaust-p/av10-airsal-47mm-bridge-kit.htm
Be careful about using a stuffed crank, might push the primary compression into a peaky powerband.  
Also be careful using heat on these cases, the crank seals got a little toasty.

5 of 5 Gr1and Gr2 french racers favorite Tuesday, January 2, 2024
taco eater : Tomahawk from LA  
Those cases are really cheap. Port match them with a good 50cc kit air or h20, stock crank, stock mbk cdi, curvy 19 intake, athena rubber stock 2 reed block, 19 dell'orto spigot carb, bidalot or doppler pipe, and you're flying.
The only problem with motobecane engines is the stock variator restricted by its small diameter and too heavy will snap the crank at high rpm. You have to get a racing variator (bidalot or doppler) but unlike peugeot they don't exist with a clutch function so you are forced to buy a rear clutch pulley to keep idle (mykitech or doppler).
