I would settle with a decent used one as well, any advice on where to find one in NL?

My friend os more in need of a users manual, rather than the service manual.

He needs some instructions how the release button on the back wheel is used for instance.
Can you support me in this so I can share the knowlege?

We´ll see what happens next…

I have enjoyed this forum and it have given me a lot of valuable information and knowledge as well as contacts.

Thanks to all and have a great Piaggio-life.

Best regards Ingvar

Ive seen this engine run with a 78 jet for a few rounds of cross without problems.

Sounds crazy but the adviced jet is 82 i believe.

The power output is much more comparable to puch and others than the restricted 3 stud engines.

Your next challenge would be to fit a worthy transmission.

How about a peugeot fox engine complete…

How about the small canal from the exhaust to the compression release, is there some gain with filling it and making it blind?

I don´t use it and it just puts pressure on the head gasket.

The blind canal may create some turbulence in the exhaust like the blind canal on some new EU mopeds but this…[Lees meer]

What about the minor leak of the reeds, will that reduce the top end power or is it mainly affecting the low end power?

I do have a DrEvo because of the race regulations that stops me at 70 cc´s so I had to go with the 43 mm cylinder.

To be picky, I do have an PVL ignition, not an HPI but thye are quite similar I think.

ArvidW :
The crankshaft of my simo2007 engine survived starting with a drill. However my variator got damaged when the nut got loose after multiple starts. But the compression a simo2007 engine is way higher than a 43mm vespa cylinder so I think you should be fine.

However I think you should be able to start the bike by pushing. There are an…

Have you heard of any destroyed tap while starting the engine with a drill?

misterd11 :
how are you going to cool your cylinder then?? Are you going to make de cylinder liquid cooled?? And nice color by te way!

The race distance is very short, only 75 meters, and I will put scoops on to send oncoming air towards the cylinder so I expect that to be enough.

Time will tell if I´m right or not.

I have two exhaust that I will try and see what works the best for my setup.
One is a Polini Top One and the other one is a Simonini Proline.

Martino :
No need for the spacer from your first photo.
Also no need for low speed, so the other plastic ring could also be forgotten. 😉

Thanks for the input.
What is it indended for?

I assume I must use the Malossi spacer in the red ring.

The plasic spacer was out of the plan for me, no need to reduce speed in my opinion…8)

asabada :
The engine wasn’t running smooth. that’s why i changed to CP. Betwen the electrodes there was spark. And the timing of spark was delayed. I never found the cause of that so i switched to CP. And that doesn’t work too. The spark is almost black because the Malossi 63ccm is new. INstead of making 3,5% mix of oil, I have bigger…

I don’t think anyone would just “know”. you mean the sloping part on the crank where the flywheel gets “clamped” on, right?

What kind of tools do I need for milling the crankcase?

I´d say get an high speed grinder, like this: https://online.tools.se/#/?article=V70-wc494166-2072774

You need to use the red one indeed 😉 I don’t really understand what you mean with the different killswitches.

NO is Normally open, NC is Normally Closed.

ArvidW :
Power didn’t rise, acceleration from standing start improved drastically in the period when the clutch was slipping. Wheely from standing start was easy. At speed it did behave just like with flywheel except for the throttle response.

Idle was worse than before, it had to idle at a high rpm to keep running.

It was one of the…

ArvidW :
Why use a CDI ?

Get standard contact breaker points, a battery pack, a standard capacitor and you can ditch the flywheel.
Works perfectly on a 50cc engine.

Yes, great idea but I prefer to go without breaker points and find a solution with a Hall trigger to send the ignition point to the coil.

Can;t you just put the battery on the CDI and connect the wires right?
won’t that work?

No it won´t.
You know that there are a small picup coil inside the flywheel that gives the CDI unit the signal to send the spark to the plug.

Without that coil no spark will be sent, the CDI will not know when to send the spark.

This is one of the shortest reduction factors out there. Better find a longer one if you want more top speed.

There are some exceptions on the ratios, but they are very hard to come by.
