MOPED ARMY

Looks like you read this already: https://www.mopedarmy.com/wiki/Motobecane_7

Sounds like the upgrades mainly consist of swapping parts from the higher horsepower models and not a lot of aftermarket stuff is available. I would say search for forum posts about people working on these bikes to get more ideas, and make a post in the Buy/Sell forum asking for the parts you need as a start

Doing the basic maintenance like regreasing wheel bearings and all the other tips in Fred's Guide will help eke out every bit of performance currently available to you.

Might be worth reaching out to the French moped gurus:

Rebel Moby (on this forum rarely now but active on Facebook) and Tomahawk Mopeds (on this forum rarely but active on Instagram.) Bonus chance of getting help from Tomahawk if you can speak French :) (edited)

Yeah, the seven is more along the lines of a solex. Made to be slow on purpose.

Luckily it does have av7 cases. If I were you I'd get an av7 cylinder and Piston, 15mm intake, sha 15 carb and a standard av7 pipe. Correct carb jets.

Basically, you'll be spending all the money to make a 45mph 50v to get a 30mph 7.

If you have the 15mm stock intake you can easily swap to a 15 SHA, and get a 70cc airsal kit, set ignition timing to about 1.3-1.5mm btdc, leave the rest alone actually, that should be plenty good for a solid 40 with out destroying everything.

The 25mph version has a larger rear sprocket and smaller intake, but if you can find the 35 rear and big intake then you should be good.

Its easier to read.

You are either going to have to drill out your stock intake or find one from a fast model 7. The 50v "bendy" intakes have too much bend. The aftermarket short intakes are too short.

Hugh, it is an AV7. Like the same one as the other av7 bikes. It's just mounted differently.

Hey everybody,

Thanks to everyone that offered advice! Thanks Mike for recommending I contact Rebel Moby. I did, and he's given me some sage advice already including a suggestion for modding the exhaust.

Also, thanks Jesse. You've been very helpful in this thread, as well as many older threads I've found on the Moby 7! I've looked around online and posted in the buy/sell forum and couldn't find any of the 15mm intakes. So I took it to a machine shop, and the guy should be calling me back pretty soon about whether he can bore it out safely or not. So, hopefully a 15.15 SHA is in my near future. Also, thanks for the explanation on the cylinder kits. I was wondering why I always saw the 75cc and 50cc kits at the same price while the 70cc kit at $25 more, but the vibration explains it.

To Hugh, based on the wiki it is mostly an av7. I think the main difference is just the cylinder head since it mounts differently. I was actually offered an av7 from someone in a PM, so you're not the first person to suggest that.

I'm still in the process of disassembling everything to check gaskets, seals, bearings, clean, regrease and all that fun stuff. Those damn motor mounts are just warping the washers on my homemade tool (help me PB Blaster, you're my only hope)! Now I guess I just gotta decide if I want to kit it or not, but if I'm replacing gaskets anyways it's certainly tempting...

Thanks for all the help and advice. It truly is a weird, but awesome little bike! I'm already used to car forums so I try to do as much reading as possible before asking questions, but you dudes have been very patient and helpful so thanks for that. Loving the moped community so far!

Thanks again, and feel free to keep dropping advice/suggestions on this thread if you want!

Oh my god, I didn't see the "/s" and you got me sooo good! I'm jealous of the fab skills, but that thing is a death trap! What a legend, RIP.
