was the polini racing lower power than leovinci ?

In this message by you "setting the carb like this is a good basis for a testride where u can fein adjust the setup, no worries nothing will happen." Tuning vespa on mainstand and without air filter and get decent setting. After test ride with air filter fixed, and when rev appears to be on lean side when bike stationary. We can tune it again to the richer side correct?

Ive been looking at your videos for years. Great work. But skip the music when you are talking please :)

Or... buy a new yss every 3/4 years :D

Hello sir. Wanna ask im currently stick with 23/67 gear with vmc 10 molle clutch. Pwk33 keihin, with rd350 reed , right handed exhaust from sip. 60mm stroke, malossi 187 aluminum cylinder. And i wanna make mine PX rev higher, cuz i ported my exhaust port to 190. It's now 190/130 exhaust n trasnfer duration. But i got hard time hitting 8000rpm at 4th gear. Do you recommend i change to 22 teeth to make my bike lighter? Theoretically it would rev higher @ every gear including 4th right? Thx Ps: the most rpm i hit @ 4th gear is around 7600rpm, gps hits 80mph, i heard if i can rev higher @ 4th gear i can get more top speed can i? Thx again

Do you do this on a si 20/20 as well?? 😊

Sir i changed the rubber but still it is dropping. Can i make thicker rubber

Hi boss fmp! For a pnp of quatrinni m1x 172 with 57mm stroke. Do we need any modification to be made for the squishing or just pnp of the cylinder head fitting sir?

Hi is there any difference between SI26E and SI2626? Thanks in advance

Hallo Sir, i have many confusion about my SI carb. I’ve changed my old carb with the new one because i’ve broke the fuel chamber thread. After the new carb installed, the engine will instanly die if i lean the bike to the left. Even if it just slightly lean, just like waiting for the traffic light. Any advice sir?

Any solution for rpm clock?

Hi. I have same symptoms. Just a big standard px125 with sip road exhaust. Jetting completely standard apart from main jet is 105. Would reducing main jet help issue? Bike comes back to idle ok at the minute.

What year is the sh300 your driving in this video i have 2012 sh300 and i wanted to know if olhins fits my sh

Should the hole under the choke plunger be a through hole? I’m assuming when you operate the choke, fuel comes in from the bowl ,up through the choke jet and into the bypass and once the engine is running, you close the choke which therefore cuts the fuel supply? Now, I have a few carburettors, that when I shine a light down the choke mechanism chamber, I can’t see it in the choke jet chamber, and I have some where I can see the light pass through, hence my question . Thanks

Hi and thanks for your Informative videos 😊 One question: I could need some advice regarding adjusting the crankshaft to the center after putting the engine together ? Are there any known tolerances to this ? My crankshaft is sitting 1mm closer to the flywheel side. Do I have to pull the crank to adjust for the 1mm ? My engine is a 1964 VNB5 Thanks in advance 🙏🏻

I did the same thing since the hole prone to be clogged if just opened a bit

Italain fingers. I bet they slap hard 😮

Damn, that’s a really good tip, brother. Thank you.

"Has anyone tried upgrading the Vespa's rotary valve to the LML reed valve model? I'm curious to know how this change affects fuel efficiency while still maintaining the original appearance of the bike. Also, I’m considering this upgrade to avoid constant repairs on the rotary valve. Any insights on performance improvements or challenges would be appreciated!"

Hi fmp! What sufficient mj size should i go for after doing this 2.5mm bore? Set up is 57mm standard stroke(replacing soon with 57mm mazzuchelli) M1x quatrinni 172cc 26/26 si carb with 150/BE3/160 Air filter modded at heart, thinner mesh for more airflow Sip vape Road flywheel Sip fast flow tap Bgm ultralube clutch 11inch Sip rims

Definitely don’t go wrong using some of that stuff

24x35x6?

VMC252 mit dem Q244 vergleichen? 😂

I have fitted the Gri.eca system but find the braking poor, do you use different pads than the organic supplied???

Hi FMP, I recently wrote to the manufacturer and they replied that SAE 40 mineral should be used. in any case they replied that they also obtained good results with specific GL4 oils. I use an 80W90 GL4/GL5 mineral and I'm fine with it. I can send u the reply if u want.

Maybe this is way off topic, but for aftermarket brake drum, especially for 1964 vespa vbb, which one do you recommend to really get good braking, BGM, SIP, Pinasco, or others. And which brake shoes for the brake drum do you recommend the most? Because to get the original brake drum in Indonesia is very difficult and very rare original drum condition (New Old Stock) thank you.

Does the weather in our country will affect the premix ratio? Like example, in Southeast Asia countries its very hot and humid here. Do we still stays with the 2% ratio or have to increase abit? Thanks in advance.

I bought set bitubo shocks and they ride soft and very nice. My spine is happy as well. I had yss. They nice but bitubo next lever. I had massive stability problem. All fixed now.

Grazie per info, mi hanno regalato a Natale SIP RBB e FBB x Px li conosci per caso? sono buoni? Ti ringrazio

Ciao, complimenti per l'ottimo video che hai fatto, volevo farti una domanda, ho preso il cilidro della VMC 177allumio stelvio, carburatore 24/24 ER Pinasco e frizione 8 molle della BGM, quello che volevo sapere devo per forza cambiare il rubinetto del serbatorio ? e quale andrebbe bene e marca se puoi , grazie Paolo

I see that you are surgeon for vespas so i'm writing you this comment, i just put a 118 mainjet on my vespa because the last owner put a 100 mainjet on a dellorto si24/24e carb on vespa px200 which is definetly not original so i ordered the new one. i'm not a mechanic but i learn really quick so how do i start her up. i got her to start and she ran great (but i didn't set the carb properly), same day but in the evening i started her and she ran and she just died, i thought that the idle screw is set too low so i screw it in, she started and she ran for a little while and then died. after that i cant start her. i put the air mixture screw 1.5 from fully screwed, i also changed the cdi which i did a good job. now after i start her up she dies because she chokes, then i add gas and she dies but she dies even if i dont give gas so what do i do?

What would recommend for mildly tune vespa just asking 👍 Have a great Christmas cheers for all your posts ...Lee over in uk

Trima kasih salam dari Indonesia 👍

Polini cast iron with 60 crankshaft doesn't have high temperature problems? does it overheat?

Hi. I'm on quattrini m1x 172 kit with malossi vespower exhaust. Running on 26/26 standard spaco carb with 150/BE3/160. Still find the fuel supply is not enough. My spark plug tip now is in white, i afraid of any overheating incident might happen to my piston head.😖 Any advice sir?
