lol
ao fim de ler tanta coisa percebe-se rapidamente que o que a team 35 desenvolveu e no minimo de dar valor.

Daí a fazer algo que nunca ninguem fez nao é de todo verdade...

pelo fotos que vi parece-me ter bastante potencial...

o que nao quer dizer que seja so chegar colocar e fica bomba...

nao sei a estrategia dele mas se fosse eu a desenvolver um cilindro deixaria o com muito pano para mangas mas ao mesmo tempo como e para ser uma coisa vendida ao publico em geral faria um cilindro fiavel, deriavado ao preço de custo de produçao tambem.

depois tal como polinis e italkit ha parradas deles ...

mas os que se destacam sao apenas meia duzia...

se essas meia duzia de pessoas que preparam itakits e polini pegarem num cilindro team 35 aposto que faram algo com potencial....

o que estao para ai a dizer de ter isto ou aquilo e relativo...

o que realmente importa no meu ponto de vista e o que acompanha o cilindro....

escape eletrica carburaçao etc....

um todo sim define as potencialidades do mesmo...

outra coisa que estao sempre a comparar e preparaçoes de uns e outros....

esquecen-se e que essas pessoas que fazem preparaçoes ou reparaçoes meximentos etc tendo mais ou menos fama nao fazem sempre trabalhos topo, mas sim trabalhos muitas das vezes com orçamentos defenidos pelos clientes....

claro que se o fulano X gastou 100 paus numa preparaçao no lufo, depois nao pode exigir que ande mais que uma feita no team 35 de 500 paus...

É que todos os dias vejo ouço comentarem preparaçoes de um com a preparaçao do outro...

Esquecem-se e de perguntar qual e o valor de cada preparaçao...


Á que saber fazer escolhas tambem, se eu tiver 700 euros para gastar numa prepaçao nao vou comprar um cilindro team 35 por uma cambota e pronto.... acabou

neste mesmo caso o mesmo valor de 700 € da para aplicar um italkit polini etc com cambota escape e eletrica carburador etc com niveis de potencia bastantes satisfatorios...

se temos 1000 para gastar ai se calhar ja se coloca um team 35 com escape carburador cambota etc e os resoltados serao bastantes satisfatorios....

por outro lado se temos 2000 € entao pegamos num de rs com carburador escape eletrica cambota etc e muita mao de obra e faz-se as tais dts dos 180...

Comecem a tentar ver as coisas tal como elas sao.

e nao julgarem as pessoas ou o trabalho dessas mesmas pessoas por uma ou outra mota, que preparam.

Comparar investimentos só faz sentido em preparadores que já se sabe terem um nível de resultados práticos similares ..

Mas mesmo assim, por outro lado, mesmo em motas com investimentos parecidos, o propósito de cada preparação pode ser diferente ..

Uma pessoa pode investir 1000€ numa DT para andar a curtir na rua, com depósito auto-lube, bateria, com peso "normal" e tendo em vista uma fiabilidade maior, sendo a mota feita por um preparador " bom ".

Outra pessoa pode investir 1000€ numa DT noutro preparador "bom" mas cujo objectivo é só para corridas de Drag ( toda descascada, com o mínimo indispensável de peso, garrafa de 1.5L de água a fazer de depósito de gasolina etc etc  ).

Não seria de espantar que a de Drag irá ter mais performance que a outra .. isto falando de preparadores com nível de resultados semelhantes em geral ..

Não se esqueçam que no caso destas motas pequenas, 50, 100, 125 etc o factor relação peso/potência e componentes de atrito pode ditar o resultado final ...

Por exemplo, duas DT com 28 cavalos:

Uma ter pneus 110 atrás e 95 à frente, corrente 420, depósito cheio e andar com um condutor que sabe explorar a mota mas pesa 85kg.
A outra ter pneus Michelin fininhos, corrente 415, depósito a 1/4 e andar com um condutor que sabe explorar a mota mas com 60 kg

Ambas com a mesma caixa e transmissões semelhantes

É óbvio que a 2ª vai ganhar .. em disparo e ponta .. isto tendo em conta que os motores são praticamente iguais no dyno ..

 que o problema principal era estarem a julgar a performance de um cilindro em funçao de uma ou outra mota que os estavam a uzar...

Um motor de dt tanto pode ter 250 , 1000 , 2000 , 15000 E la investidos em peças no motor ..
E nem sempre tem a ver com o investimento ..
Mas todos sabem que quanto maior e  o investimento ,
maior e a probalidade de alcançar prestaçoes mais elevadas (obvio)
os preparadores regra geral  ninguem trabalha ao maximo .. uns trabalham a 70, 80 , 90 e a ate os que trabalham a 100 % dos conhecimentos que posuem ..
depois tambem ha a durabilidade do material em relaçao  a potencia (obvio)
Por isso desafiar ou comparar  as motas que um preparador ou outro preparador mexe ..
e e coisas tipicas dos putos da primaria .. nao faz sentido .. porque cada um tem a sua maneira de trabalhar ..
por isso a melhor maneira , e desafiarem diretamente os preparadores ..
pois qualker preparador que se preze .. tera sempre la  uma maquina encostada para tirarem algumas
duvidas ou conclusoes ... ou mesmo cairem na realidade !! e ficarem totalmente a toa.. ou nao !..

É claro a grande maioria do pessoal nem sequer sabe das corridas do pedro, se quem vem para aqui falar que as motas dele sao isto e aquilo,
vao ver as motas dele no campeonato nacional, simples 50'ccs com amortecedores e suspençoes ohlins ai sim voces veem o que e uma mota a andar.

I am from the North American side of the world. Pedro only writes in Portuguese, so comunication is a little difficult, but we managed to confirm parts and prices. I sent payment, for cylinder, pipe, crankshaft and shipping which was about 1000 Euro.

There was a bit of delay as he was on vacation in January and he appoligised about this. In late March he said the parts would be sent, so now it is late May and I haven't seen them. I have wrote 2 emails to confirm, but no reply. I know sometimes skilled machinists can be busy, but it is important to make sure customers are kept happy. I have avoided making comment on this forum for as long as I can but soon it will be 6 months!

I am crossing my fingers that the parts were sent and will arrive soon, but it will be 8 weeks since when he said the parts were sent. I don't know if Pedro is on Facebook or if he has friends so I can make contact.

It is a shame as I am impressed by the parts he has, I would purchase many more in the future, but at the moment I am not sure!

Hi

I have a friend from Brazil who said she could call if I needed help. If you have his cell number this would be useful. Most of my friends speak Azorean Portuguese so they say it is more difficult to speak with mainland Portuguese speakers.

My other choice is to travel to Portugal, I originally planned to as I was interested to see the workshop and be able to pick up parts when there. I find it difficult to find information on Pedro, what he looks like, the shop etc. I feel more comfortable when I know more about a company I plan to order from. I have ordered parts from Taiwan, Japan, Thailand for 20 years and never had troubles.

These are some of my bikes.

Speaking for myself, I will do anything I can to help you. It's been 8 weeks since the last contact, right? There is a problem that can often delay shipping from Portugal to outside the European Union, called customs. Try to call them and ask if they have any retained item in your name. When you learn anything, or if you don't, let me know either way.

Hey thanks everyone, sorry to distract from the cylinder topic!!

I'll just be patient and wait. I wanted to contact Pedro to find out how he sent the shipment. Air, surface etc?  If by surface, sometimes this can take time, though more than 6 weeks is strange.

We never had many D T Yamaha's unfortunately, when we did have them it was 15 - 20 years ago and we never tuned them as were as the ones on the forum!

I did try calling in January, but those who answered only spoke Portuguese, Pedro later emailed and said he was on vacation.

When I use google I write as correct as I can, then take the translation and translate back to English to see if it is the same as what I originally wrote. If there are friends of Pedro who wish to send a pm to me and can write English this can help.

romeuhramos, I'll have to write to you as I think you have good experience with your bike, I think I see you on Pit-lane sometimes, good place for technical understanding. I also help my friend with TM125 race kart and I used to race a Honda RS125 a long time ago.

I got email from Team 35 today so this is good! Hope to find out when parts were sent, it is possible they were sent later than they said they they were. It is always difficult to understand meaning using google. Has anyone been to their shop, workshop? I might see a friend in Madrid, I could travel across and meet them. I want to learn why they make so many options!! There are many strokes and bores. Is the longest stroke and biggest bore always best?! I wished I had a DT!

About the longest stroke and biggest bore, in my opinion the longer the stroke the less engine speed you get, but the power band can be wider. The best option may be to build a square engine, bore = stroke, it is best concerning engine balancing and you can get a good power band with good torque. In your projects, how do you usually build the engines concerning these variables?

I agree that perfect square bore / stroke is the best option. Old school 125cc engines used 56 x 50, the modern engines use 54 x 54.

This was always a problem for my choice of bikes that no one produced a longer stroke crankshaft. Derbi, AM6 engines have the choice for longer stroke crankshafts, but I was never aware this was possible for the Yamaha, Honda etc. So this is something exciting for me as I always wanted a longer stroke. So for me I always use the standard crankshaft and tune within that limitation.

I find with the 41mm stroke the engines work well up to about 50 - 53mm bore. Going bigger it becomes difficult to keep a good top end powerband, I think filling and exhausting the cylinder becomes more difficult and piston runs hotter. A modern KTM 85 is 48.95 x 47 so is a slightly long stroke motor which could be a good design. It gives better port area and reduces diameter of piston.

My question about the longstroke engine option is, is there disadvantage? More vibration? More wear? Why make a 43mm stroke option, if more power can be made with 46mm? Is it to keep within rules for racing classes?

Hello Scotty, I'm the person that talked with you via email some time ago due to problems with the cabling of an Honda NS1, I have lost your contact, so its nice to re-meet you in this forum.

There are more advantages in getting more stroke in this small engines than disadvantages, because even with a 54mm stroke any modern engine can rev to 14k rpm or more, and you always gain torque with the extra stroke and at the end of the day the biggest stroke always wins, due to the increased torque and increased cc of the engine, as you also said, all the ports can have more area, and in a 2 stroke engine the limitation is the area that you can get in a port without exceeding the desired time(the degrees that each port is open).
The italkits cylinders can be used with 43mm stroke with no radical modification, like huge spacers under the cylinder or the piston going inside the head of the cylinder.
And as it as been proven over the years an engine with 54mm x 43mm bore is a killer deal.

Hey BTK,

send me your email in the pm so to remind me!

I understand not needing radical modification as a bonus for the shorter stroke, so that makes sense.

That's an interesting ratio, 54mm stroke with 43mm bore!! Does this exist and work well?

Yes, a very large number of the dt's around here use that configuration, and can get a pretty good top speed, around 150km/h for medium/high end engines, and that is in motorcycles without any fairings, the italkits are also used to some extent in the honda ns1's in Spain, but due to the limitations to be able to race they use the stock honda ns1 cylinders and call pull about 22-23 hp at the wheel with stock bore and stroke, but tuned engines with the 54x43 diagram can put about 30 hp at the crank, have a nice wide power-band(usually the narrow power-band is due to ignition limitations and to agressive exhaust, and the wrong idea o gigantic exhaust ports, I can get about 13k rpm with just 184º of exhaust timing, and ready made exhausts) and over-rev up to 14k rpm.

If you want I can get the Pedro phone number, as I have some friends that know him very well, but I live a bit far from him so I cant talk in person with him.

I think you have been meaning 54 bore with 43 stroke?

Yes, that's what he meant. AM6 engines are also promising, the crankcases need some work, but the stock engine already has good crankcase volume. And there is also the large availability of parts, like bigger stroke crankshafts and some promising cylinders and close ratio gearboxes.

I don't know much about the AM6 engines, I do now have 2 Derbi GPR's one with a Euro 2 engine and another with the Euro 3 engine. I've been looking at the 50 x 45 90cc options from Airsal and Barikit. I guess these European engines must be quite similar in design?

Good to read everyones thoughts and learn from different experiences.  :educated:

I think the engines are quite similar, yes. The cylinders available appear to be the same too.

I am also looking at the 50 x 45 Barikit, looks very good. I think it will work well in conjunction with a 28mm Mikuni TM, a close ratio gearbox (haven't chose the right one yet), maybe a Barikit exhaust and a fully programmable ignition system like MVT digital direct. It may be an expensive project, but I hope it ends well when I finish it. The engine will fit a motorcycle with a total weight (engine included) of less than 90 kg.

There is another interesting cylinder for these engines, the Parmakit 110cc, I don't know the tecnical specifications, but some say that cylinder when bought is quite poor and needs some port work, but can be promising. About its longevity, I don't know if it's good or bad either.

I agree with you, it's good to share these kind of experiences, we always learn something new  ;) I don't know much about Honda engines, but about DT 125 and AM6 engines I know a bit more ;)

RLopes, one thing, the Derbis use Derbi engine and not the AM6 engine, the Derbi as the advantage of having a much improved gear-box, and as straight cut primary gears instead of the helicoidal cut of the am6 ones, another advantage is the reed-cage that as 6 petals instead of two and the reed cage is also much longer and thus having more intake area, also I'm not sure but I think that the derbi engines have 20mm crank axles instead of the 17mm that the am6 engines have, and to finish, the crankcases in the derbi engine is bigger which allows more space to tune the engine and is the best engine to mount one parmakit 110cc cylinder due to the extra thickness of the crank cases.
The 54mm cylinder and 43mm is a commom measure in the yamaha dt 50 engines, but in the old ones that derive from the 80's yz 80 engine, and not the yamaha dt 50 that as am6 engines.

RLopes, you sound like you have a similar idea to me! I think the Parmakit is too much for those engines, too many loads so that they would be a bit fragile. I never measured the, are they actually 110? I would have thought if they aimed to make them 100cc that would be a good compromise.

BTK, thank you for the clarification, I had doubts about the similarity of the two engines, I always thought that the Derbi engine was an AM6 but with a better reed cage, now I see the differences are many ;)

Scotty, about the Parmakit, I remember I once made the math and the volume was very very close to 110cc. About the fragility of these engines, I can say the worst part is the crankshaft. I once had an AM6 equipped with a Polini 47mm with the stock crankshaft, the engine was tuned to achieve about 13500 rpm at full load (47 bore x 40 stroke) and the previous owner had the balancing shaft removed to minimize friction (he forgot that the vibration its lack causes is far worse than the friction it reduces). I only realized that when the crankshaft broke by the bearing (ignition side). Luckily, the connecting rod remained in place and did not destroy the cylinder and many other things... lol looked for the balancing shaft... Gone.

These engines have another major flaw... The gearbox. It is simply terrible, that's why I thought about replacing it right from the beginning. The gear ratios are a bit weird, and shifting down requires some, lets say, skill... It wears down quickly.

This engine, with tuned crankcases, a good crankshaft and gearbox, and a good reed cage (maybe a V-Force) may handle well the Parmakit. I prefer the Barikit though, it's certain that it will last longer, and the engine is for street use, not for racing purposes, so I can't afford to repair it almost every time it leaves the garage...

Confirmed, 55 bore x 46 stroke, equals 109,28 cc.

So nao percebo uma coisa, nao quer dizer que este rapaz seja, mas axo que as coissas nao funcionam assim..
imaginemos que agora crio um user e venho praqui diser isto e aquilo e que so falo italiano e digo que um de voces me fez isto ou aquilo, so por ser italiano eu é que sou o verdadeiro e nao digo mentiras?  é preciso ter moderção como se acolhe um membro sem o conhecer de lado nenhum e sem saber as suas intençoes.. volto a referir que nao sei o que realmente se passou e nao quero aqui estar a defender ninguem nem a incobrir.

-- Mas se houver mais algum caso destes mas que o user em questão seja portugues que se apretense aqui tambem.   :happy:

Hey Limon,

I don't want to cause any trouble for Pedro. I just need to get information as it is a long time since I ordered and sent payment. If you understand when you order from another country from a company on the internet it can be difficult to trust. I do trust he posted the parts, it is just concerning as it is taking more time than should be expected.

Sorry I cannot speak Portuguese, my grandfather did, but he never taught my father or me.
