[@vladanpesic3756]

I did everything with you tube clip. Expanded carburetor. Exhaust made more fluid. The engine is more elastic and pulls better. The transmission may be shorter. I am very satisfied. With minimal investment, I got a much better engine.

[@FreakMoPed8]

thx for sharing. Very happy to hear that! maybe u could also post this on ky fb page? that would be great Cheers mate

learning english from my videos? oh wowh, i am blushing :D :D

[@josemariaarino854]

Verás lo que dura ese motor sin enganchones... Nunca se puede ampliar tanto la lumbrera de escape. Los aros pasan a través de esta. Esto vá a romper si o si. Una auténtica chapuza!

[@FreakMoPed8]

no worries. all engines run fine. the limit where it gets dangerous, is never overstepped of course. thats self explaining. original exhaust ports are very tiny. u can widen them quite much, without any danger. the secret is to round the edges, if they are too sharp, rings might get damaged, thats true

[@syahrulismail2184]

Thanks for sharing your information.👍👍👍

[@muratunyay6573]

Thanks for sharing your information and experiance so far I'm very pleased which spark plug do you recomend and what should be the electrode gap

[@FreakMoPed8]

8ngk and standard gap, i never remember it 😄 sorry

[@vladanpesic5804]

Thanks for the good video. By how much the height of the head is removed?

[@FreakMoPed8]

You can take off 1mm

[@apisunda2972]

For small handpieces, do you use a foredom?

[@eltiponegativo5570]

I gonna try on 52.5mm set of lml 125. I hope similar performance as 150 5 port are achievable. I was very happy with 150 5 ports, mazzu full circle, boysen reed valve and scootopia big box exhaust. Drt 23 cogs as well did pretty good job. Now I want run similar setup but with 52.5mm cylinder with your mods.

[@FreakMoPed8]

always set timings, there is a ot of potential in there!

[@marcomatthijssen1915]

I have a veloce with a 22/22. Inlet of engine case matched to it and inlet opened to give it a longer inlet time. It runs great and super smooth. The only thing I would want to change is to let it rev a bit higher. What is it that limits the revs so much on these original cilinders, exhaust port timing and volume?

[@danielbottcher1497]

Hallo ist es ratsam den Orginal Vergaser 20.20 gegen einen 24. 24 zu tauschen oder nur zuviel sprit Verbrauch und schlecht abzustimmen? Habe die Version 3 vom kolben O tuning 150.

[@FreakMoPed8]

rentiert sicherlich ja. jeder gaser ist abstimmbar, nur die frage wieviel zeit man sich nimmt dazu. und auch ob der motor gesund ist natürlich.

[@handyman7297]

I have a 1996 vespa px 150E, this model has a 3 ports engine like the one on this vídeo???? Which vespa uses the 5 ports kit?

[@FreakMoPed8]

Lml

[@peterwriede7772]

Can you do exhaust rising to a Nikasil cylinder kit (BGM 187) or can this only work with Iron cylinders? I am 0zero on the barrel rising and I think I'm getting 131 transfer and 176.8 exhaust duration....

[@FreakMoPed8]

u need tobcalculate it

[@marioariasleiton2475]

Great video! Can I try this on my Vespa150 and add a 24/24?

[@FreakMoPed8]

Yes, absolutely. Make sure carb fits casing and casing the engine case. Also extend intake Timings.

[@thBrnfc]

with this setup, do i need change the clutch or its ok to use the original clutch?

[@FreakMoPed8]

its still ok

[@airaaira7484]

hi mista .. may I learn from you about how to modify the Vespa engine to run faster ... without using branded parts? i want it

[@FreakMoPed8]

what exactly do you mean...

[@airaaira7484]

What we need to change when the TDC piston is a 2.5mm buried position from the cylinder lip

[@airaaira7484]

because I use piston Japanese motor ...

[@danielefantini835]

Just want to describe my engine so someone can take some benefit of it: 150 tuned (original timing 150/120, tuned 180/120) Piston only removed the two reinforcement down on the "mantello" New drt storke 60 conrod 105 (now the timings of the cylinder are 186/126 placing an 1.5mm down the cylinder) crankshaft retarded of 10° and the suction valve is 120/60 26 pinasco spaco 22/68 (too long, cant use the 4th gear, stops at 6000 rpms i need to place again the 20/68) Tested with expansion chamber and a normal box exaust ( ricambio rapido road racing) and if impressive with the expansion exaust..... its like to have a exaust valve, once you pass 6000 rpms it gives you an impressive boost and brings you ut to 8000 rpms in 1,2,3 gear... but at the end it stops at 95 kmh since the 4th gear dont go up more than 6000 rpms... same speed, just some more torque on the low revs, with the box exaust, just less boost once passed the 6000rpms... probably gonna place the 20/68 and keep the expansion, really good sound and impressive power...

[@FreakMoPed8]

Thank you for the detailed info! . your timings are too high, try get lower. Not the power turbo kick and makes you fast, a wide band does. thats why it doesnt pull the 4th i would have recommendd 118/174, the thing is that with tunung you need a LONGER transmision usually, and you are still faster as the short one. A short one would throttle the engine / cut its power

[@danielefantini835]

@@FreakMoPed8 ho could i reduce the timings rn? should i remove the 1.5 mm down the cylinder? but then i whould have the corner of the piston out of the top of the cylinder (we are talking about 0.75mm) so i should compensate adding a sort of copper gasket of 0.6/0.7 on the top of the cylinder.. am i wrong?

[@joeladzim1225]

hi sir, i know its an old video.. but do you have any running comparison video? just curious i'll do this very soon

[@FreakMoPed8]

Sry, no, this cyl i gave to someone in thailand :) bu checkout the latest otuning light video, there is a before and after comparison

[@potatogarage]

What jetting is recommended with 150cc O-tuning, BigBox exhaust and SI 20.20 carb?

[@FreakMoPed8]

depends on cylinder timings, exhaust port, intake timings and exhaust

[@potatogarage]

LML 150cc 3-port cylinder, Transfer 115deg / Exhaust 172deg / Intake 150deg, BGM BigBox1 pipe (old version)

[@fabricioadippe190]

Hi , how do you know the mm of the exhaust port that you should raise and width? How you calculate the %? Thanks

[@FreakMoPed8]

thats maths, radian measurements

[@esencia78]

How many improvement in terms of performances :-)?

[@FreakMoPed8]

a LOT. in all gears. no loss nowhere. original 8-9hp engine = 5-6hp rear wheel. otuned it will be similiar to a 177 pnp cylinder so 10-12hp = 100% more power.

[@esencia78]

Awesome!

[@danielbottcher1497]

Hallo könnte ich ein Bild von der Version 1 bekommen? Wenn ich das richtig gesehen habe. Beide Stege unten heraustrennen und die Kanäle hochziehen?! Und die Bohrung oder nicht? Mfg

[@aryafaisal1867]

With this tuning, should the cyl head resquished?

[@FreakMoPed8]

Makes sense to raise compression a bit, yes.

[@aryafaisal1867]

@@FreakMoPed8 in your tutorial stated that stock exhaust port is 55% from cylinder bore. As far as i know, stock piston px 150cc is 57,8mm and 55% from that is around 31-32mm. How do you measure it? It looks different. N, how can you get the number to raise the exhaust port to the top of cylinder? Danke 🙏, im just curious and willing to learn..

[@xperimental1974]

how much BHP it will get?

[@FreakMoPed8]

10-13 i guess

[@yudhithekid]

Is that possible to replace the 20/20 carb with 24/24 for this 150ccm tuned engine?

waw emezing 👍 hello I from in Indonesia 🙏

[@FreakMoPed8]

thx. cheers mate!

[@januarchris]

thanks for sharing. With this tuning , do I need a bigger carb like 24? or it is ok with 20? and also for the exhaust, does the stock exhaust is good , or should I change the exhaust as well?

[@FreakMoPed8]

For a first step you can also start with the si20 yes

[@fabiotiburzi]

I run the 150 5 transfer. Still on si20 but jetting is very rich. It’s 140 be5 108 and 160-50 3 turn out and it’s a monster

[@fabiotiburzi]

For the exhaust, if you are in town stay on the original, it has a good low end. If you want more buy something better

[@agghell224]

You are the best !!! Can we do the same tuning on px 200 ?

[@FreakMoPed8]

Sure, but U have to open the side fake ports

[@agghell224]

Thank you mista. It would be so nice to watch a video from a vespa guru like you, of how much power can we get from the original cylinder (i think it s about 18-20 hp)

[@FreakMoPed8]

no, thats too much expectation. 13-15 instead of 9hp original = +50% with box, it has small channels which limit, dont forget. malossi sport 210 pnp = 17-18hp, polini 210 = 14-16hp

[@agghell224]

​@@FreakMoPed8 i was speaking for px 200, thats why i asked you if we can do the same on px 200. It s 12 hp from the factory and i think that 18hp is the maximum limit...........but you know better. I would like to see how much do we have to open the ports, and the box with the fake ports and by using reed valves do we have to open the rotary valve distance??? and many others things from a specialist !!!............before spending our money on a tuning kit :(

[@FreakMoPed8]

the money on a tuning kit is well spent, 18hp is not reachable with the original 200cc cylinder, it simply has too small ports.... try get a used polini 207, optimize the piston and be happy. contact me over the facebook page i do have 200cc kits laying around, perhaps if i am bored one day i will make a guide ;)

[@SingkongBikir]

How to 60 mm stroke mista?

[@yudhithekid]

Could You make a video about LML 5 ports tuning?

[@FreakMoPed8]

it does not depend on the cylinder its always the same cooking recipie 1) cylinder timings 2) exhaust port width and shape 3) intake timings (if rotar valve) 4) exhaust 5) cylinderhead just watch the timings guide: kzbin.info/www/bejne/g6eqf56tZsxpeZo and the otununig px150: kzbin.info/www/bejne/kHTRi2WKaamlsLM new otuning px200 upcoming ;)

[@yudhithekid]

With that 150 o tuning, is that need to advance the timing at the stator plate or just stand at IT mark?

[@fabiotiburzi]

I did it. It depends on what do you want to do. 60 mm stroke with 110 conrod is more powerful, but you need also more fuel. If you do a 57 mm stroke here's what I did. I raised 1mm the cylinder and 2-3 mm exhaust (because mine was a knockoff) to make transfer port from 108° to 115° and the exhaust from 150 to 175°. Then open the exhaust up to 65% bore. I noticed that the exhaust duct was a little small so i enlarged by 4-5 mm. If you are on reed valve, optimize the front exhaust transfer port to the valve. If you are on rotary, do the usual stuff (cut 15mm on the cranckshaft and balance it on the other side and cut the rotary valve to the famous 120 before tdc and up to 65 after tdc. I went from stock to 13-14 hp and now it is a monster

[@FreakMoPed8]

the lml is not reallt worth it, very low timings which means you have to lift the cyliner quite high = shorten it on top. Better take a vmc superg

[@fabiotiburzi]

@@FreakMoPed8 yeah, unless you have very low budget
