Ah, OK. So to open Sense I need regulated 12V DC? So if it was a battery it would be ok? Or could I use the 12V AC blue wire? I wanted to try this original rectifier because I already have it. But if it can't work, I'll use the BGM one.

Maybe someone thought about it and i missed it. If yes, then I am sorry and please direct me to the correct thema. But a quick question... Can this work? Or how would you modify it? Thanks.

I already have from a previous project the VMC reed valve adapted to PK, so I wouldn't to buy another one. But I also think that the 34 carb is a bit too much. I have a PHBL 26 for a test but I think about the flat slide VHSH 30. Maybe I can try with the 26 for a change. It could consume a bit less.

So another year, another motor... I rode nearly 1000 km on this motor, but I should have known that the crank will give up... I heard that the BGM have a sometimes a bad pressfit and I think that I also overpowered the crankshaft. It's a shame I didn't have the time to measure the power. Anyway, It went with a BANG! Crank is done and so are the cases and the cylinder is OK but the head and piston are dead! But what now? I want to rebuild completely my PK, but before that I want to prepare (hopefully) one last engine with around 18-20 ps and test it. Cases are sandblasted and I need to decide on a cylinder. I found cylinder for 240 euro and crank for 280 euro. What do you think of this setup? Are there any changes you would do? 2025 engine (18-20 ps) VMC ET6-60 alu cylinder (126°-186°) Fabbri Mover with ø87 crank halves (because I have a bored out side case) VMC reed valve ø28-30 and modify it to 34mm VHSB 34 10-15-18-20 Malossi 27-69 with Fabbri basket EGIG Taipan Bolla Elaborazioni HP clutch Vape Sport

Beschreibung: Vespa PK 50 XL mit Quattrini M1L Preis: 2800 eur --> 2600 eur Standort: Klatovy 33901, Czech republic Hello, I am selling a Vespa PK 50 XL with Quattrini M1L. It is registered in the Czech republic in my name. The problem is, that the engine has (most likely) a twisted crankshaft. The engine can run, but it scrapes the crankshaft against the case. I drove +-2000 on this engine when it was okay. I can fix it, but right now, I don't have the time to do it, so I am selling it as a winter project for someone. The original 50cc engine is also aviable to this Vespa. If you are interested, write me. And if you act fast, the price is negotiable. Thank you.

Hello, I have a few parts for sale. I am located in the Czech republic in Klatovy. Shipping is possible or I can drive 30km behind the german border. If you have an offer, feel free to send message. Thanks!

Ok, thank you for your help!

Question for the experts... What exhaust can you run on these MV frames with a p125 motor, so that the main stand doesn't hit the exhaust? Polini box hits the stand :( and I dislike the MRP relocation kit. Original PX - clears SIP road 3.0 - ??? Expasion chambers - ??? What about taffspeed mk4 left hand exhaust? I can have one for a reasonable price... Thanks for your replies ;)

It is because I know a few german words and I want more people to understand the drawings. Sorry, if it is a problem, I will only write in english. Still thanks for all your help. So option 1 it is! I will prepare for the milling and bring some results in the upcoming week.

Ok, then how about this? I thought of a plan on how to save the cylinder. I measured the aluminium base gasket and it should have been 8mm but it is 8.3mm. I can correct this and the piston ring still wouldn't be able to pop out of the cylinder. Then I can use a small port-cutter to raise the ports about 1mm. If I do it correctly and good, the angle of the port shouldn't really change. I know the timing would be excessive but I think it could work better then it is now working. Which of these options would be best? If you have other ideas, I really welcome them.

Yes it does work! Find a M10 bolt and a soft bread and then stuff it inside, hammer it, stuff it,… repeat until the bearing pops out.

Now I have it all dissasembled, sadly found a small issue. What do you think? Nicasil isn’t cracked, only aluminium is on it. 600 sandpaper to scuff it up and same on the piston and run it? The tolerance between cylinder and piston doesn’t seem like it changed. Also, first time I have used the bread technique. I didn’t think it would work 😂

Squish was 1.3mm for 54 stroke. I think that is too much. On 51 stroke the manual says 0.9mm. How much squish should I aim for? I think 1mm is adequite. On the side of jetting, I have tried many combination - k57 k24 and also a lot of different emulsion tubes. I cannot remember all of the combination, but I think I should start to take notes 😅

Hello! After 3 years of being on this forum and just watching from the sidelines, I want to create a small build project of my own. More precisely, really fine-tune my dream project. I´m from Czech republic and as far as I know, I am the only idiot :D in our country, who wants to have a crazy smallframe. I have a German market PK XL with Quattrini M1L-56 which has broke down due to bearing failure on the secondary gearbox shaft. But before that happened I drove it for a few kilometres and the engine did not feel right. Before it gets to "power" or "ressonance in the exhaust" there seems to be a dip in the powerband and I don´t know why. Hope you can help me and sorry I´m writting in english, my german is not that great.
