man, u r so detail!

THIS IS GOLD! You Sir, deserve some Belgian beers!

Thanks, mates. Learn a lot from you.

thank u so much

Its like you are reading my mind, I'm just fitting a 57mm mazzu crank to my malossi166 and this video came in perfect time. One question, do I need to cut my mazzu crank to extend the closing time to 70 or can I cut the rotary valve on the case?

💓vespa indonrsia, mr

hi sirr.. where can i get timings tables for english version

for a person understands how to adjust ignition timing on 4T Scooter : it is really veryhard to understand how to adjust timing on Vespa or scooter that has no valves .. but I try to understand ..

nice vid. are you still active in this world? cant find that tool anywhere.

Any idea for malossi 166 mk3 timing? Need to optimize my current setup

Hey sir, i have a question about 5:47 how did you convert from mm to degree° ? you really help me understand a lot of thing & i appreciate your effort explaining all this, thanks ! -------------------------------------------------------------------------------------------------------------------------------------- ps : im working on piaggio ciao / si / bravo ( rotary valve ) My problem is i adjusted the gasket below the cylindre, because when the piston is at BDC ( ports was not fully open ), so i add 1.5mm to fix it, now the ports are fully open, but the timing is bad, after i turned the engine on, he went crazy idle & hole in acceleration, i knew it's coming from the gaskets that i add below the cylindre. now im trying to fix, i did a lot of research, im still learning but i want to be accurate. here's some info's if you cound give advise or help and thanks again. -------------------------------------------------------------------------------------------------------------------------------------- ( PIAGGIO CIAO ROTARY VALVE ) inlet open : 112° inlet close : 53° total inlet : 165° conecting rod : 78mm stroke : 43mm pbt : 3mm -------------------------------------------------------------------------------------------------------------------------------------- ( TEST 01 Gasket 1.5mm below cylindre ) Exhaust port duration : 103° - 257° = 154° Transfert port duration : 118° - 241° = 123° -------------------------------------------------------------------------------------------------------------------------------------- ( ORIGINAL GASKET 0.1 very thin gasket - ports cylindre not fully open at BDC ) exhaust port duration : 102° - 249° = 147° transfert port duration : 121° - 235° = 114°

kann man nach diesen Modifikationen noch den original Zylinder verwenden oder sind diese dann nur noch mit dem tuningzylinder kompatibel? Gruss

Herr Moped, I'm still confused why you add another scratch mark on the closing time? What was that for?

Based on your experience, what rotary pad times do you recommend for a malossi sport 221? The engine has also a polini box and pinasco 26 SI.

Thanks for your master tutorial, i also how did you convert from mm to degree° ? I want to know may i looking for download datatable about strock relationship with degree (60mm.....57mm to ....degree). Have any formular? Help me! and Thanks again!

Hi,,how to optimize the reed valve timing?

Why raising cylinder does not change the pbt measurement?

كم هي كمية الزيت المطلوبه داخل المطور الثنائي 150cc

What does blow down mean?

what cylinder it is?

Can't understand the logic of 112+45=157degrees. If it starts open when piston is at 43.1mm from the top cyl which is 112degrees and closes at 10mm from top cyl which is 45degrees, then the oppening time shouldn't be de difference between open to close which in my mind is 112-45=67degrees? This is freaking out my mind and can't understand where i'm thinking wrong here :)

you make the 8th day....to repare la Vespa...!

i watch the hole video and didnt understand anything but still i think you know too much about vespas
