The Reso is lowerd to arround 10000 rpm peak and in 6 gear max rpm is 10200-10500 max so you need 17 gear than 16 for more topspeed. The Italkit with jolly pipe 34 dellorto can do 35-37HP @11-11500rpm. the polini with his 154cc pipe and 34 dellorto does also a 37hp but at 10000 rpm. The polini reso pipe has the nr 4257 and a warning NOT FOR ROAD USE, USO ESCLUSIVO SU PISTA, RESERVE A LA COMPERTITION. i have the pipe since 1999, also the 154cc kit. 4 new pistons and the same zylinder. 40000km+ an the engins still goes strong
@@bravo1412 I didn't have that luck, my 154 broke down the first day due to the last owner not knowing how to set the carb up. I'm planning on rebuilding the cylinder but am hesitant because they are not as reliable as the others. Any tips for making it more reliable
Good morning Mr.Pochi,i' am always happy to follow your videos. I'm considering purchasing a 54mm charmo cylinder and would like to have your opinion on it. Alternatively I can evaluate the italkit cylinder, what do you think? Thanks in advance, greetings Mauro from Italy.
In my opinion, I did not see any particular problems with the quality. I think it would be an option if repair parts such as pistons were easily available.
When changing to a bigger bore you need also change the exhaustpipe, otherwise no gain in power, but the opposite. At least when talking about the RSA Racing of 2007
The detonation counter is a model that I sold in Japan but it has already been sold out. It can not leave a data log. Therefore, I check by recording with a video camera.
The Italkit's cylinder is a totally Italkit's design and production. Bc's cylinder is a modified Aprilia cylinder so you have the original Gilardoni's and Aprilia's quality.
Italkit Gen 1 was also a bored and ported genuine Aprilia cylinder. The new Italkits are a new cast, different to the original aprilia barrel, but they're still made by Gilardoni. They seem to have some really bad conservative porting though. Also we don't know if Gilardoni is the one who does the plating for BC's cylinder.
I only know because I saw there face book a while back and asked as to why they are no longer making them. Was told by bc engineering team they will be making a new version
Hi Pochi, I have a problem with Aprilia RS125cc with Rotax 122, cylinder italkit 140cc, piston model vertex. After 2 3 hours race pace the piston dents. Can you send me a brake-in procedure or give some advice. Thank you in advance.
@@PochiRS well I am not sure, this is why I am asking for advice. The bike is used for racing in Bulgaria. I am not sure whether I should lower the ignition timing(current 2mm from TDC) or should I use higher octane gasoline(current used 100 octanes). The coil is selettra CDI, compression 13:1, exhaust is jolly moto corsa.
I don’t understand why you want to put big bore kits on the bike it just ruins the bike the original 125 cylinder is great and can be tuned my rs 125 track bike / has v force 3 reeds/ full arrow titanium exhaust system/ ram air sponge filter (no airbox) 28 vbsh cd racing carb set up properly/ racing ecu unit/ racing ht lead / heavy duty clutch / domino throttle/ and the bike does 112mph and has 34bhp and a 0-60 time (my personal best) of 5.7 seconds and a rave 1 power valve (the best valve)
Pochi you’ve focused more on lightening your bike than actually learning how to tune it properly your bike is awful no offence, the kits ruin the bikes capabilities
I just think you’re trying too hard, and try the v force 3 reeds you will see a massive difference in throttle response and how the bike accelerates, especially if you are running a sponge air filter (cone) but you just have to jet the carb up correctly and you will have a lot more mid range and a better flow of air/fuel to the cylinder

even the frame of that bike is beautiful
Thanks!
Thank you pochi. Its sounds sweet straight out of the box.
Hi Pochi, many thanks, I'm glad you finally received your BC's 144 cc cylinder. I hope you will enjoy it, at full throttle! :D
It's thanks to you.
I want to ride on my aprilia of the new cylinder as soon as possible.
But Unfortunately, the rainy season will soon come to Japan.
I can understand you. This summer is yet not come here, it rains all day, incredible!
I may be able to ride on the RS if it is sunny after the second week.
I hope the weather is clear.
Let's cross the fingers! :-D
And have a test in the Dyno. ;-)
I had a italkit 140cc before. Now a polini 154cc. Cant really tell what is best.
Conversely, Both of them may be best.

Nice Circlip tool👍 and doing your sqish nice
I use the tool very conveniently because I am clumsy

Hi Pochi, where do you find this tool to install the clip in the piston? Great tool! Greetings from Belgium! :)
Robyn Racing I also would like to know
You can buy it on ebay.
Dan King is after your special oil pochi be careful😂
tiggz rs motovlog 😂😂
Actually we all want your special oil pochi. No seriously we really do
Beautiful! :)
Thanks!
Top speed on 144cc?
So beautiful
Thanks!
wow good
which detonation counter are you using and which system to record the data?
The detonation counter is a model that I sold in Japan but it has already been sold out.
It can not leave a data log.
Therefore, I check by recording with a video camera.
what is the most powerful cylinder to rs 125?
I don't know exactly.
The actual output does not match the perceived speed.
Il suo cilindro originale, lavorato da un bravo meccanico è il più potente
Did you noticed any differences from Italkit to BC 140?
Worth the price difference?
It is difficult to answer that question. But I don't think it makes much difference.
What oil did you bake the piston with? Is it homemade or did you buy it?
There are oils on the market which, when superheated, form a film. It is unknown if it actually works.
That music tho 😂
What is the BLADE for rave2 for? Will my mk1 rs125 chesterfield 98 model require this part if i go for the 140cc bc kit?
Why not find out about exhaust valves on 2 stroke engines?
Hi. What is the minimum and maximum size between the piston and the head should be.
about 0.8mm
@@PochiRS how do you get to this size?
Which is the best cylinder between italkit 140, mitaka 140, bc engineering 140 and charmo 144? (in terms of performance and reliability)
Honestly i don't understand
So I wonder which one you can buy
@@PochiRS which is the best between those cylinders?
Oh, now you got the BC kit. Any first impressions compared to the other kits you've tried?
Thrasyvoulos Vlachos yes I would like to know if it is really all that great like people say, and how it compares to the italkit cylinder.
Probably,I can't tell the difference between the two cylinders, because I'm slow.
Pochi you keep saying that but actually your pretty fast on track
The Italkit's cylinder is a totally Italkit's design and production.
Bc's cylinder is a modified Aprilia cylinder so you have the original Gilardoni's and Aprilia's quality.

Hello mr. Pochi. How much does Charmo and BC engineering cylinders cost? Which one is cheaper?
The cheapest is Charmo. Because it was obtained in Japan without importing.
You also have the option of MITAKA.
@@PochiRS okay. Would it be possible for you to send BC engineering cylinder to me, and i will pay for everything. How much would it cost in total?
If i have 180cc two stroke engine,how much squish band i need?can you give me an idea sir?
I don't know.
Racing? Street?
The conditions are different.
Whats this give you? like extra 2 BHP maybe lol
Is that a dry clutch setup?
It's not.
hello mr pochi..which is the best cylinder?
I am satisfied with the BC Engineering 140 cc kit.
I thought bc engineering has stopped making the cylinders now. Did you buy the last one?
My cylinder kit is the second to last.
Maybe.
I only know because I saw there face book a while back and asked as to why they are no longer making them. Was told by bc engineering team they will be making a new version
I know. The new version seems to be 144 cc of a 58 mm piston.
Did you not want the 144 kit or unsatisfied with it?
I will also purchase the 144 cc kit.
It is a lot of fun to try.
Hi Pochi,
I have a problem with Aprilia RS125cc with Rotax 122, cylinder italkit 140cc, piston model vertex.
After 2 3 hours race pace the piston dents. Can you send me a brake-in procedure or give some advice. Thank you in advance.
Is not it a result of detonation?
@@PochiRS well I am not sure, this is why I am asking for advice. The bike is used for racing in Bulgaria. I am not sure whether I should lower the ignition timing(current 2mm from TDC) or should I use higher octane gasoline(current used 100 octanes). The coil is selettra CDI, compression 13:1, exhaust is jolly moto corsa.
How about making the main jet bigger?
Do you have reliability issue with charmo
Not sure if the quality is good enough to recommend to others.
@@PochiRS I have issues with the piston but cylinder are ok. Which big bore kit do you recommend?
I now use HTM Racing 144cc.
They have a supply of pistons only, and I am going to use that for a while.
@@PochiRS compatible with charmo cylinder?
I haven't done that verification.
I don't trust the pistons any more than I trust the CHARMO cylinders.
How about top speed after chnge block?
I don't know about that, because I don't get the maximum speed on the track.
Pochi nice.. i also got rs125. After tune up, i got 190kmh..
I don’t understand why you want to put big bore kits on the bike it just ruins the bike the original 125 cylinder is great and can be tuned my rs 125 track bike / has v force 3 reeds/ full arrow titanium exhaust system/ ram air sponge filter (no airbox) 28 vbsh cd racing carb set up properly/ racing ecu unit/ racing ht lead / heavy duty clutch / domino throttle/ and the bike does 112mph and has 34bhp and a 0-60 time (my personal best) of 5.7 seconds and a rave 1 power valve (the best valve)

Just do what you want.
I do too.
If you don't find my video interesting, you can watch others' videos.

Why not 154?
Does 154 cc cylinder run over 12000 revolutions?
That haven’t hit my mind. But i think i’m gonna run 154 for street use.
Mirip buring ninja
What?
I could not translate well.
Its same like ninja 2 stroke
Is it about KRR 150?
It is totally different.
That's one mean chainsaw.
