Nein, das ist eine M3XC/"Quattrinni für M1L"

So, I asked a shop selling LML base gasket for the 5 transfers cylinders and it is about 0,6mm thick... It still does not explain the low squish... If I use this gasket (not aluminum) I expect a squish around 0,8 maximum; This is far too low !! Maybe the LML cases are different ? Can anyone confirmed this ??

Ich habe von meinen freunden von http://seventies-scooter-pieces.com/ eingekauft Aber der Preis hat geändert, weil die Market (... ) ist jetzt teuer Edit: Heute habe Ich gelernt das der LML Dichtung Zylinderfuß ist dicker als Piaggio !

No comment I now better understand where comes the metallic sound and the material on my sparkplug !! So be careful, this is a stock LML 5 transfers cylinder with specific head on a stock Piaggio PX125E cases with normal (57mm) crankshaft... One need to mount at least a 1mm gasket !! This is surprising thought.... What should be the minimum squish for this kind of configuration ? I believe 1,5mm ?

Ok, thanks ! The engine you're refering too is also an LML 5 transfers ? Do you think that too much compression + unleaded fuel 91 octane could be the problem ??

Where can I get a 0,8mm spacer/gasket for PX ?

I would be really interested in the official LML setup because.... I also have knocking issue ! My story is a little bit long, sorry for that.... I have this metallic sound that I believe is related to winglett vibration and/or piston tolerance, AND I discovered on Saturday that I also had real knocking ! So, on Saturday, hot day, around 30°C on the air, 2 on the scooter, I was running 160-BE5-110. After 15 minutes ride, I opened full throttle in 4th (-> Heavy load), I drove like this for 2-3 minutes ( I was still giving the engine a break from time to time), but this time I could here a stronger metallic sound. I felt that the engine was not pushing as strong as before, so I engaged the clutch... and it stalled almost immediately . I was freewheeling for 100m, then I re-engaged the clutch and engine started again, then stalled. I stopped, waited 15s, and then it started again, no problem. I looked at the spark-plug: ligth brown-colour with lots of metal deposit -> knocking !! Back home, I checked the stator setting, it was sligthly after IT, around 19°. For safety, I turned it clockwise to the maximum, around 15-16° I believe and I put a 160-BE3-118 main jet. I also realized that my air manifold (carb-to-frame) was sligthly not well put, so I fixed that. I thought it was now... But no... Yesterday, much cooler day, on my way home in the night (15°C on the air, still 2 people on the scoot), I drove 4 km at 70% throttle, then I attacked a light hill for 5-700m, then 200m after it, while in the descent, I engaged again the clutch to make the engine breeze a little bit, and... surprise... it stalled again (Even nicer when you're on a road forest at 22h with no moonlight !!) Soooooooooooooo, Here are some facts and assumptions, please discuss: * Engine has always high compression, so I do not believe there is an air leak at the cylinder head * Does not seem to burn the gear oil, so clutch-seal ring should be fine * It has a very stable idling and engine drop RPM quite fast, no oil leak on the stator side, so the other seal-ring should be fine * I am running Unleaded fuel, 91 Octane..... Could this be the problem ?? I'll switch to 95 to see... * Could this be that compression is too high because LML cases are slightly higher than PX ? I am saying that because squish seems very low (I will measure tonight): At TDC the piston is really leveling the top of the cylinder, and the cylinder head squish band is not that high... * Could this be that piston touch the cylinder head ? * I have a standard Piaggio PX gasket; Could the LML be thicker ?? * Should I change my jetting ? 140 main air jet ? Spark is brown... Before blaming the cylinder kit quality I would like to investigate any other option... Thanks for your help !

Hallo Leute So I have mounted the cylinder on my engine. I have chamfered all the ports, enlarged by approx. 2+2mm the exhaust port width and 1mm height. And that's it ! No work on the cases, this is my daily scooter, I had no time to correctly adjust the transfers and I did not want to take the risk to do it while the engine is in the frame. My carb is a SI24/24 for 200er, with 160 BE3 110 and 55/160. Ignition is still on IT (18°). My crankshaft is anticipated. Engine is running great since the beginning, it revs not really higher than the PX125 (it seems mainjet 110 is too much... I find it strange), but it revs much faster thanks to the 1mm chromed rings. It has also lots of torque, for instance I like to start in 2nd gear, and then rapidly go in 4th, very pleasant for city driving. Compression is quite high, you can feel it on the kick ! The only downside so far is that I hear some small mechanical knock, but it cannot be "knocking" due to timing. First I thought it was the piston/cylinder too big tolerance, then I thought it could be the piston bearing/piston axe, but actually I start to believe that what I hear is the vibration of the cylinder winglets... I have to check... So, besides that, I find the experience very positive so far If you can find the complete cylinder at a reasonable price, then it is definitely worth it By the way, if one can give me the complete 5T LML 150 carb setup and timing, I would be interested...

Nein, glaube ich das ist eine ET3 Zündung (elektronisch) mit eine V5A Polrad (nicht elektronisch)...

Ist die "Standard" Lüfterradabdeckung genug mit Varitronic und abgestimmte Maschine ? Keine Thermische Probleme ? Danke,

Ich habe anrufen, nich mehr Prüfstand in Wolfsberg (A-9400) Kennen sie einem nahe zu Villach (A-9500) ?

Ponys

Mit meinem altem Polini, denke Ich das ich bald einem Prüftest machen werde (in Wolfsberg)

Der Auspuff für den M1L

Leute, Hat man M1L zylinder mit M8XC auspuff zusammen probieren ?

Zehr schön Und hast du mit einen Varitronic probieren ? Edit: Besser ?

Hallo Leute, Haben Sie der MC0 von SAVA probieren ? Katalog: http://www.savanorthamerica.com/bin_catalo...atalog_2007.pdf http://www.sava.de/start06/scooter_racing.html

It would be nice to have some pictures of the new track ;)

Bastard !

edit: found

Wo in Österreich kann ich eine Prüfstand machen ?
