If you want a higher top speed go with a bigger front sprocket
If you dont modify your chain wont make it past an engine bolt inside. you have to remember that the sprocket is larger.
When you first get a biturbo it also has to be "Broken-In" so if u havent rode it alot then maybe all you need to do it ride it for a longer time
If you get a 27 tooth you will need to modify the engine case.
Would a 1977 Motobecane 50L use Leaded gasoline? Just curious?
I Have a similar problem, and I'm missing an air-box ...this is what the problem is i think, If u dont have one...get one.

I've been working on a 1977 Motobecane 50L. It has no air-box. And i have looked High and Low to find one, No luck. If ANYONE knows where i can get one please speak up. And i do know this part can be expensive since it is hard to find. Im pretty certain I need the Square air-box. The carb intake faces the right hand pedal. PLEASE if anyone knows where i can get this don't hesitate to let
Heres the last picture of the whole bike. and as you can see its in good condition.
Picture of it from the front...yes it has a Hole to let air in.
Compression Is good... and ill send a pic Sunday.
I've been working on a friends moped and when you give it gas it will start to speed up then Cut out then Speed back up...then down ECT. When it finally warms up it will have little cut outs on/off. any help would be appreciated this is a 1978 Hero-majestic Ankur.
Positive, its coming from inside the engine case where the flywheel is located.
I work on mopeds as a hobby, and im new at it. Would anyone know what i might be hearing on my friends Tomos Targa? When I give it gas and stop the tires with the brakes something inside the Clutch And/Or Flywheel Rubs and makes a horrible noise (metal on Metal) And it does it when you take turns around a corner and some other random moments.
Well i Don't have a air-box to my 1977 Motobecane And So i took a plastic box with a small hole and Rigged it to fit over the Air-box Section. Now tell me will this actually work? I can now start my moped without spraying gas into the carb, so that tells me I changed the amount of Air its getting. Now if anyone knows I can only see one Adjustment screw And would anyone know what IT should be
They should, but go search online for the rim width and size, but they shoul work. If not modifications should not be difficult and very obvious
Well To answer your Question, yes its possible to mount a 43 but you need to be a good mechanic to make it work...your best bet is to stick with the 22.5
Yes it only has one adjustment(idle) and it's too hard to adjust with the choke always on...I'm going to take it to the shop Tuesday and have them fix the choke. Its one weird choking system.
I'v unclogged my carb, but i still have to spray gas into the jet to get it to start, once it starts i can keep it to run, but i have to keep giving it gas. If i let off the throttle it cuts right out. My choke is messed up, but i don't know if its stuck on. If it is will this be keeping it from idling?
It's had to explain what happens. The carb was cleaned in a carb cleaning machine for several hours, maybe there might be something clogged. But when i attach the line fuel stop compleatly, it doesnt even seem to go into the carb. But i'll take it all apart and check all the passage ways.
And Yes I realize i spelt my topic Fuel flow (Fule Flow), my bad.
I'm am compleatly stumped, I had my carb cleaned and rebuilt, and when the gas line is attached, the fuel does not flow at all. when i pull the line off it flows all over the place. The fuel line does not even fill, i can see the same air bubbles in there all the time. This is a 77 Motobeacane, and i've checked the filter and the float all seem good. but the gas does not make it out of t
You might have a bad coil. Or a short circuit somewhere.
I have a motobecane too... look behind the belt wheel...there will be a fork grabber. make sure that fork fits between the teeth ...you'll hear a click.
I dont think it the torque. I just got new rings for my motobecane, and the problem is that your engine has a hard time running because the new rings cause it to have really good compression, once the rings break in it will idle fine.
Ill do some research, but at this point I don't exactly know what the problem is.
OK dave. you said you saw gas leaking out the muffler... this is unlikely, but maybe your float inside the carb is sticking. I had a brand new carb once that did the same thing. After i took it apart i noticed a piece of Styrofoam was lodged inside the float bowl. (the Styrofoam came from the packaging it came in.
I don't think so...my Tomos has no plastics and it does the same thing. Its been rattling off/on for a year now.
