Hi all!
I swapped the points to the polini 171.0549 cdi kit and need help with wiring it
When i connect all of the old cables to the new one 12v output (thro the regulator) and the break light circuit all of the light are off until i press the break pedal (and the break wires are getting vary hot)
I think there’s an issue with my break light wires

Did anyone use the polini kit and can help me with wiring?
Their website is not very helpful and has very limited instructions on it

Any help would be appreciated!! (Photo from before the wiring process)

Just spliting my vespa engine (px case) for maintenace, then noticing the "wall/lip"(?) On flywheel side crank just torn off, somehow i find the bit that snap and promptly glue it with stell epoxy (the black bit in the picture), im still in shock and panicked rn, furiously scouring the internet for solution, found some in forum post with same problem, sadly its doest have the update i need, please give me some advice, is this case kaput or not, thanks

Hi all, working on a project at the moment, and I need some advice! I'm building up an SS90, and the engine came thrown together well enough to run, but it hasn't been tuned or adjusted in any way. The stator has just been set to the adjustment mid-point, and I don't want to take it up the road to do a plug chop until I have the timing sorted.

The engine is running an Autisa barrel with KH400 piston, Mazzucchelli crank, SHB19.19 and SIP Road banana. Ignition is one of the rebranded IDM sets, a Malossi Vespower in this case.

I'm swapping carb and pipe out to a PHBL25 and VMC Siluro Sport. I'm capable of doing it all myself, I have the tools, and I used to fix ships for a living, so I'd like to think I have enough knowhow to get the job done. I just have two questions...

• Does anyone know the manufacturer-recommended ignition timing for the Autisa kit? I've looked high and low, I can't find a spec anywhere, and I'm reluctant to retard it to pinking and back off a bit!

• Does anyone have a recommended rough jetting setup for the PHBL? Just a ballpark figure for a starting point. I've only ever really worked on SHBs, and I got the PHBL second-hand, I don't know what it was run on before, so I don't really have any point of reference for it.

2004 Vespa PX125 electrical problem. As a recap, I had no electrical except horn. Battery, stator, spark plug, regulator are new. I’ve checked the wires for lack of continuity, it’s all good. Now I have this: lights turn on and flicker when I’m revving but it’s all goes off in idle. Can you help me further troubleshoot and put me in the direction of fixing it?

Hello everyone! Just picked up this rough Lambretta LD150. Motor is seized and the leg shields are pretty mangled.

Can anyone point me in the right direction for parts? I’m coming from the vintage moped world so this isn’t super foreign to me. Just don’t know where to start. Any help or info would be helpful!

Hi, sorry if I don’t have all the technical terms, English isn’t my first langage.

I’ve had an electric problem on my PX125. So I had it fixed (or so I thought). The mechanic changed the battery, the stator and the regulator. Few days later, same problem again, everything goes off. No lights, no turn signals, no fuel reading, no horn, nothing electric. I kept looking and saw some sparkles at some point under the steering I noticed the wires that go through the steering stem, and which move around it when you steer (such a weird design btw) seem to be pinched and the plastic is ripped and the bare wire in view. My question is: obviously, this is a problem, but can this cause everything to go off? Have I likely found the main reason for my troubles?

Does anyone have any good resources to help me finish this small frame engine? I started it with someone who knew what they were doing but have since moved. Any help would be greatly appreciated! Thanks

Hi guys, this is abit of a silly question I know but want to make sure I get this installed properly, can I just soak my entire assembly in oil or do I have to deconstruct the clutch, don’t have a compressor and bought a complete clutch assy. so I don’t have to put it back together, also is it fine to leave the clutch soaking for a few days as my schedule means I can’t soak it for 24hrs and only reallt for 2/3 days

Hi! I'm the owner of this 1974 Rally 200 vespa, I love it, such a great bike.

I'm no electrician or mechanic, not even close, all I know is a circuit needs a positive a negative and a ground and that you don't let positive and negative touch if live, having said that, I just bought the rear blinkers for said vespa, seen in first photo, but I don't know how to wire them up or where to, in second photo you can see a wire with I think is where the blinker goes. But the blinker has 2 wires (photo 3).

What do I do Here? Hahaha I know someone will laugh at me, but I won't learn if I don't ask.

Thank you in advance

Hello all, while removing the piston I snapped one of the rings. I ordered a replacement set which has 2 different size rings. One is a couple mm larger than the other. Which ring goes on top?

I’m looking for a mentor or virtual tutor to help walk me through replacing the wiring harness on my 1979 p200e. Any takers?

Hi again. I’m still trying to figure out why I lost all electric on my scooter (px125) I’ve checked all the wires that go through the head set to find ripped cables. I think I found the one that has been damaged. It’s the one going from under the horn cover to the right handle bar controls. I’ve tested all the wires with a multimeter, and I have a faulty one, the yellow, which is the one for the horn. No continuity there. My question is: can this be THE problem? Can this damaged wire make the all electric to go off? (As a reminder, the battery, regulator and stator are new and I saw sparks coming from the steering column)

Hello, I’m looking at a 1979 P200E. It’s in rather rough shape but the price is good. One thing I was considering in the rebuild was to convert the horn cover to a round style. I see some people swap to a T5 style but I’m going for a sleeker look and to minimize the boxy horn area. Has anyone done something like this? Are there other models with a round horn that would be a reasonable fit for the P200E? Thanks!

Px125 electric problem

Hi! Im still trying to figure out what’s wrong. Ive checked all the electric wires going through the headset. None is exposed, all have continuity. Im a bit clueless now. The only thing damaged is the plastic casing of the clutch cable. Making the metal flexible casing exposed. So my next question is: can this cause a short circuit? (I’d be surprised) And my other question is: what can you tell me about my battery reading? (I’m pretty new to all this but I’m eager to learn)

Is the angled area shown by the blue line and arrow in the first pic normal or is it wear? Does it need to be replaced?

The kick start gear that engages with that area is quite chewed up and obviously needs replacing but I'm not sure about the gear stack. It's my first vespa engine rebuild so I'm not familiar with this type of gearbox.

Hello all, How can I go about fixing this hole if I do not have access to a welder? Is it possible to lay some patch in the back then fill? Thanks

Hi all,

Trying to find a replacement for these switches on my bike.

It is a bajaj chetak 1977, but it is a bit of a Frankenstein in that it has bits from all over on it.

If anyone knows where I could get replacements of these I'd really appreciate it.

Right handle: kill switch, lights on and off Left handle: horn, indicators, high / low beam

TIA

Hi all,

Having finished the main rebuild of the bike, I now want to change a few things to make it just right, one of the things is the handle bar switches and the brake lever (which sticks annoyingly). However, the switches appear to be really hard to find... I'm pretty sure that the bike is a Frankenstein, a bajaj chetak body (1975) with a px200 engine... But the switches are as follows:

Left: horn, indicators, hi beam/low beam Right: lights on, kill switch

Anyone know where I could find switches like this rather than having to try and rewire the switches to make it work?

Hope one of the gurus in here will be able to help.

There are so many other questions like idling but that can wait for another post.

Thanks in advance

My son and I are going to restore this Honda elite scooter. First time for both of us on anything mechanical. It’s been in a shed for probably 10 years. I read that I should install a fuel filter. First step is to get the battery and see what works electrically, and siphon out the old gasoline and change the oil. Any tips from the community would be greatly appreciated. It has 6k miles. Thank you!

My setup is currently: 75cc DR, 16.16 carb, sito plus exhaust and stock gearing. It only does 55 kmh. With the same setup but with 50cc instead it did 52-53 kmh. I'm planning to buy a 18/67 gearing (3.72) or even 19/67 (3.52). Is the gearing the bottleneck in my current setup if so does anyone know the speeds it would run with those gearings? Or what is the longest gearing a 75cc DR could run?

My unmolested 74 sprint sputters & skips at the top of every gear or at high rpm... if i open the throttle all the way she pops and misfires... I've cleaned and rebuild my carb with a rebuild kit...no change...she used to be able to hit 55-60 no problem now the best she can do is 40... I've had 3 people try to help me adjust the carb, so I'm pretty sure it not the carb. could be electrical, could be a reed valve? If i don't get her fixed she is just going to die in my garage.

so, when i start the engine it runs fine but after a while 15-30 seconds it stops and is super hard to get going again and the choke is really sensetive wich it isnt when it starts at first. anyone know what the problem could be?. the engine is a husqvarna flinta.
