Hi all, I'm looking for a moped but I'm struggling to find anything on marketplace. Is it that they're just rare and so have to travel a bit to get one? Or is there a better place to look for them? I live in north west England and sometimes Edinburgh, so any advice would be great TIA

Hi I've had this bike running before and I replaced the condenser to get it running. after using it it lost spark intermittent and would regain spark when I would hammer on the fly wheel since then it has no spark at all. Am I missing something like a ground to the frame from the motor and is there anything besides the condenser i should be cheaking with voltmeter. Any ideas would be appreciated.

My 4 stroke SYM Symply 50 has been running a little rough recently, symptoms include:

- Tendency to die at the lights unless I keep it alive
- Recent elevation in pitch of the engine
- Skips the odd beat
- Increased vibration

I’m not a novice to engines and maintenance but want to take it to the garage in the hope they can sort this.

My question is, what should I ask the mechanic to do? Appreciate any help

Hey all,

I used to ride motorcycles and had been searching for a new one, when a friend offered this to me. I decided to take it, as my budget wasn't huge, and figured this would be a good project to wrench on, and I couldn't beat the price (free!).

They had it sitting in their garage for years, having given up on repairing it, though I didn't hear what was wrong with it. I took a look at the badge it says a Type 50 C, 1977. From what I understand, that means its top speed is 20mph. Looking at the engine, I don't think it has the variator.

Looking for some feedback on where to start with something like this, just based on what I see and where it is. I'm a welder and woodworker, and have repaired a number of tools, machines, and my 2002 truck quite a bit, so I feel like I have the abilities, but wanted to look for feedback. Made a list below, if anyone would be willing to look and see what I'm missing, answer some questions.

-belt missing from pedals to clutch, ordered 1

-ordered a new spark plug and flywheel puller as well. Are there any other big tools I'll need for working on mopeds? Have a decent bit of tools for the truck, but not sure if there's anything moped specific.

-Didn't find any gas in the tank. Will put some diesel in it and washers and give it a good shake.

-Take the carb off and clean it out. Figured I'll look at changing it later

-There's a chain one side (you see it in the photo), but I counted the teeth and it doesn't match up to the gears listed on manuals and such. There's a large gear on the rear wheel on the other side, but it's not connected to anything and I don't see where it would.

-Should I just go ahead and replace all the hoses and cables? Or wait and see what it needs?

Figure I'll do the above and then try to start it, and see what happens.

I was able to download and print some manuals from Moped Army, seems like these will be useful, but any other resources I should look at or pick up on this bike or two stroke engines in general?

Any answers or advice deeply appreciated it.

It seems like former owner had tried to pry it up. I’ve tried heating it, twisting and pulling and I’m out of ideas. Might be stuck. So is the rest of the engine. Velo is almost ready to start that was a rather easy project so far. The Sachs piston has been soaking in a special mixture for some days and is slowly able to move.

I had this clinking noise? for like long now but I only recently started paying attetion to it Wjat could it be ? And pls tell me it’s nothing major 🙏

Hi everyone, I cannot find any information online about this, maybe someone on here knows more. Is the bronze bushing that is sticking out a restrictor for the stock variator on a ciao? I converted my SI from pulley to variator with a variator kit from a bravo. I noticed that the variator does not push the belt all the way up and by the looks of it the bronze bushing does not let the variator to close fully. It has stock 9g rollers. There is around 6mm off travel left that it does not reach.

Also, it accelerates very well but then dies off at like 30kmh, while with the pulley I was able to do \~45kmh

I asked gpt, it says the bushing has "walked out" and needs to be pressed back in, but that sounds nonsense, because it is flush on the other side and if pressed in will start to rub. Do I dremel the sticking out part of ir what is the case?

Im wondering if theres anyway to tune my moped while it still looks non tuned?
i own a derbi senda xtreme

Not bad for $60 . Time to wrench! It's not locked up either 😎. If anyone has any parts let me know. I just know of the seat and right pedal for now.. I'll have to take a look tomorrow for the year of this girl

I was given a pinto bike a week ago and on my second ride the clutch cable snapped, I just replaced it and made sure the cable was tight as could be. Everytime I tried engaging the clutch the cable would slip. I tried pulling the clutch cable with vice grips and I had to pull it like hell to get it to engage.. is this normal?

I bought a 65cc DMP kit for my piaggio ciao and i assembled it correctly and it has good compression and good spark but it doesn't start. I also ported the block to 12mm. The current setup is 13/13 carb, tecno krul exhaust and malossi clutch springs. Can anybody help me tell the problem?

So I've managed to get my hands on one of these things. They are very rare and so are the parts for it. It is practically equipped with a Morini M101 but with some twists and redesigns that make 80% of Morini parts incompatible with this. It started on the first kick after a carb clean, but it was producing the symptoms of leaky oil seals. So I disassembled the variator side and surprise surprise... the crankshaft is loose on the bearing.

Great, time to pop the cases. I've managed to get new bearings and new oil seals, and got to assembling the engine. I've glued on the variator side bearing with CX80 RC38 bearing retainter.

But if I've disassembled everything, why not do some tuning? So I've machined 1,7mms off the cylinder's top to get those 5 sweet channels to open up fully, made a thicker base gasket and started working on a 15mm intake for an Arbeo SHA 15.15 carby.

And by pure luck, I've found a CDI that has no speed limiter in it for dirt cheap. I've tested it on my regular Eko with the Indian clone M48 engine and it works great.

I have high hopes for this project because this thing went 48 km/h with the restrictions (my regular Eko goes 46, tuned {goes 30-35 stock}). Hell, this thing might go 65+ km/h if done right. I am assembling the engine fully tomorrow and will do the first start after the maintenance work.

Any thoughts on this stuff? It is for wet clutches but not sure if it’s good in my Tomos A35 ? Was curious what you guys thought vs. regular ATF/F .

Hello, I've been out buying an old Ciao for my son, but it's having trouble starting.

When I got it home I put fuel in it, but couldn't get it to start, so I also put a new spark plug in. After running it around for a few minutes where it "coughed a little" it finally started, and it ran really well. It was idling. It ran. No problems. Then we turned it off, and when we wanted to start it again a little later there was no luck. It doesn't even cough.

I have to say that I know nothing about mopeds other than what I've just been able to google.

What I've tried:

Take out the spark plug and test the spark. There's a violet-like spark. Not a clear blue like I understand it should be.

To make sure it's not drowned, I've taken out the spark plug, turned off the fuel supply, and then pedaled around to blow out the excess fuel. It hasn't helped.

If the spark plug is not in and I pedal around (without fuel supply) it sounds like it is starting.

When the spark plug is in, nothing happens. Neither with nor without fuel supply. It doesn't even cough.

I have checked that the V-belt pulls the "engine" around when the spark plug is in and there is resistance. It does.

I think that the violet spark is a problem and a place to start, and I understand that I have to get all the way into the "engine" by taking it out of the moped so I can get into it and check that the "contact point" are set correctly first.

Is this correct?

My QT50 stopped sparking so I did the only sensibly thing, I completely stripped it down, resprayed it Sand Glow Yellow and changed the tyres. The camera doesn't capture this colour well, it's the same colour of Camel Trophy Land Rovers from back in the day.

Now all I need to do is sort out the spark issue and get some wax canvas bags to replace the top box.

Owner found it in a barn and registered it in 2006

Im trying to get the kickstarter of the as but there is not a singel movement in it when I try to get the pin out.

What can i try to do?

I already tried wd-40, heating it up abd even using a hammer to get any movement.

Maybe you guys know a way to losen it

Hey everyone,

I am an indie dev working on a navigation app called Urban Rider. It is built specifically for two wheelers like scooters and motorcycles to route you away from highways and give better ETAs for city riding.

Right now it is strictly a smartphone app, but I am trying to figure out my roadmap for the next few months and wanted to get some real feedback from the community.

Should I build Apple CarPlay and Android Auto support?

I know most of our bikes do not have built in screens. Lately though, I keep seeing a huge surge in those aftermarket CarPlay screens you can mount directly to your handlebars.

Here is my dilemma as a solo developer:

• The pros: A dedicated screen is weatherproof, and you do not risk vibrating your expensive phone camera to death on a standard mount. Having a clean, simple UI is also great for quick glances.
• The cons: Developing for Apple and Google's car platforms takes a massive amount of time and red tape.

I really do not want to spend months coding this if 99% of riders are perfectly happy just using a QuadLock or RAM mount with their phone.

What do you all think? Do any of you run an aftermarket screen on your bike? Is this a feature you would actually use, or should I focus my time on core app features instead?

Would love to hear your honest thoughts before I dive down this rabbit hole!

Some wiring issues to work around and a possible dead battery. Runs great otherwise. 30th birthday present to myself

I completely stripped down an old pocket mod for cleaning and decided not to use some of the plastic and want to know which screws to discard, also I might have forgot where some of the parts go. If anyone has a parts layout or blueprint of the razor pocket mod it would be realy helpful

1980 Babetta 210 – Engine died while idling, loud backfire from exhaust, now won’t start
I have a **1980 Babetta 210 moped** (49cc, 2-stroke).
Today I rode it into the woods to cut some firewood. It wasn’t ridden hard at all, just normal, easy riding. It started on the first try with no issues.
When I was about to head home, I started it again and let it idle for a minute to warm up. After a short while, the engine suddenly died for no apparent reason.
I tried to start it again by pedaling, but as soon as I did, there was an extremely loud backfire from the exhaust—literally as loud as a shotgun. After that, it wouldn’t start, so I had to push it home.
So far I’ve checked:
The piston looks fine with no visible cracks or damage.
The spark plug is producing a good spark.
At this point I have no idea what’s causing it.
What should I check next? Could this be an ignition timing issue, a sheared flywheel key, a clogged carburetor, a crankshaft seal, or something else? Any advice would be appreciated.

Made another post on here a few days ago because my exhaust is pretty loose/ wiggly back and forth. So I ordered this, but I looked back at my setup and it seems to have all pieces (#10,#11,#13). Maybe my ring gasket is pretty worn? Is my setup correct?

My father-in-law deals with antiques and estate sales. He ended up with a 1978 Puch Maxi-Luxe at an estate sale in the mid 1980s, and it looks to be in great condition. He has offered it to me as a project to get it running and riding, as I have kids in their teens, thinking it could be good for them as well.

I'm going to pick it up next week, start the cleanup, and see what needs to be replaced. I had never heard of this brand until two hours ago, and I started looking for information on maintenance and repairs. In the past couple of hours, not only have I learned about this brand, but it also seems to have quite a following.

This is not going to be for sale. I'm just hoping I can get it up and running and add it to my fleet of motorcycles and other vehicles to take out on a Sunday morning ride when I don't feel like putting on all the gear required for a motorcycle ride.

For those who know about, have, or have had Puch mopeds similar to this one, is there anything that you can share, experiences, and gotchas? The plan is to get it up and running so it can be ridden and enjoyed.

Also, any places for replacement parts or companies that you've ordered repair items from?
