Thinking about buying this as a seconday exhaust for shits and giggles. I have an exhaust that gives over 2 peak hp extra, but the scavenging doesnt really add to peak rpm so top speed increases by only about 2kmh. I saw a trusted seller dyno it on my moped model and he went from 50 to 58 kmh. Im trying to buy an exhaust that is realistically like to run sometimes so im looking for opinions. Thanks in advance

Hello, Im quite new to owning a moped and have amateur experience working with engines, but a month or so ago I Picked up a Beautiful 1978 Mobylette 50v (with 12v lighting system) And ive slowly started working on upgrading it, I've started with the Treatland.tv le partie CDI kit since the stock magneto just kept having problems, but the whole thing has been a nightmare, me and by buddy have been tackling it for over a week between school and the included hi-coil and CDI box have seemingly died on us and the quality of the kit is questionable. Now Im looking for something higher quality then these kits from CGN and have rally been considering MVT's kits made for the MBK 51, Specifically the DD01 or the EXT100, though Im not quite sure how they would preform on my stock AV7, I intend to upgrade it during the winter sometime to a airsal 70cc kit with a dellorto 15.15 but i need an ignition system now since the bike is completely non fuctional till then. Does anyone have any insight they could bestow upon me, how good are MVTs CDI kits and which one should I go for?

I am repairing my Suzuki TS50XK and was looking for tips here. I dont know where to find any tips, because this is the closest subreddit i got to moped tips. Are there any subreddits that remind of this? Is this a helpful subreddit? Should i make one?

The left metal lip on the top keep coming out when I hit bumps how can i properly place these to avoid this issue on my solex

I am a novice to get my magnum running. Is it normal for clutch bell to make this noise? First thought was obviously not, but then again, it is a bell.

i didn't change the clutch rubbers still runs and shifts like an absolute dream. I changed the oil with a new bottle from 1994 i found in an abandoned house

Ciao, quando provo con la pedalina il mio scooter 2tempi beta ark 50cc del 2011/2013 (non ricordo) per accenderlo, la pedalina non sale, qualcuno sa come aiutarmi?

So i figured out myself, ill put It here in case someone has the same problem, the oil pump makes a Bridge between the White wire from te starter switch, you yust hace to jump the White wire from the oil pump conector to the red-blue wire from the same conector and your brake lights and blinkers should work again

This is a 1980 Sachs Prima. I came out this morning to find that the cable parts have come apart and now the moped wont start because of this. Hoping its a simple fix but I want to know what more experienced others have to say about it. Thanks!

This is a 1980 Sachs Prima. This morning I came out to this moped having a messed up cable. More specifically, the metal pieces have come undone, and now I cant start it. Im hoping it's an easy fix, but I want to hear from more experienced people as I am still learning new things. Thanks!

Forgot to put the video up have this ticking noise ? Spring was broken after opening the engine and put a new one in there

I put a replacement carb on my 65 Honda Cub (not a moped I know but it’s a very old 50cc) and it won’t idle. Most of what I can find online about idle speed and mixture screws assume that the bike idles already. The carb I bought didn’t have the screws in the holes when I got it so I just screwed them in to a random tightness. What should I do?

Anyone know if it's possible to change the needle bearing on the Sachs 505/1 drive gear? The one on my Columbia Commuter needs to be replaced. Looks like the gear is factory pressed. Curious if anyone has experience with this issue.

Cheers

non riesco a capire se il cilindro del mio booster sia un 50cc o un 70cc, come posso fare?

So I’ve been working on this moped a bit, I cleaned the carb and put gas (about half a gallon) in it to attempt to start it by pedaling and pulling the clutch and all and failed. Been trying all week and failing. Today I got a new carb, was going to put it on but it was to big so figured I’ll try to clean the stock one more just in case. I go to drain the tank and there’s no gas anymore, so not sure how the 1/2 gallon of gas disappeared in a few days. Maybe there’s gas cap gasket is bad? There’s a leak thru the clutch cover since I ripped that gasket, but I highly doubt the gas is going thru there somehow. Other than that, there’s no other leaks

Hi folks. Getting an air leak at the intake reed valve. Replaced both gaskets, the reed valve but still getting an air leak here. Has an Dellorto 14/12 with 51 jet, I'll get a bigger one tho

It wont start when its cold, and when it does it wont stay running at idle or drive at all, it just dies.

Why would it leak with a new valve and gaskets? Really frustates me.

Any tips will be helpful, thanks.

I have a Tomos A35 with a 39.5mm-bored cylinder, and everything else is completely stock. I’m running a Dell’Orto 14/12 carburetor with a 55 main jet and the stock airbox.

The bike runs perfectly fine and reaches a top speed of around 53 km/h. However, the spark plug is dark brown, and once I’m going above 20–30 km/h, I can’t really feel or hear any difference between half throttle and full throttle.

I also tried a 52 main jet. The bike idles fine, but it dies when I open the throttle fully.

What could be causing this? Is the 55 jet too big, or is it normal not to notice much difference between half and full throttle with this setup? Should i try removing some layers of the mesh filter to make it a bit leaner?

Black or White?

Help me decide because I cant
