ESE's works engine tuner

38 tones thats right thirty eight tones and thats why inertia and the ram effect of pipes and ports is so effective.

Mostly 4-stroke stuff but worth a read:- http://www.gofastnews.com/board/tech...t-volumes.html.

A sample from the page:-

So air is heavy – if we add to this the fact that the energy is equal to half M(mass) times V(velocity) squared (1/2MV^2) we can see that when port velocity goes up the port energy goes up far faster and when port velocity drops the port energy drops far faster. Putting that into prospective if a port is made 20% too big the port energy drops by 44%. In basic terms that equates to a 44% drop in the ports ability to ram a cylinder by means of it’s velocity derived momentum. When it comes to combating reversion, especially at low speed port velocity is very effective. Kill the velocity below a certain level and you effectively kill torque at the lower rpm levels while not necessarily garnering any power advantages at the top end.

With the limitation of a 24mm carb and the need for punch out of the corners in Bucket racing I am very interested in port velocity.

Scroll to the bottom of the page for other aspects of porting and combustion chamber dynamics. http://www.gofastnews.com/board/tech...t-volumes.html.

Tomas is probably more concerned about you stealing his ideas for profit as although you have coverd a lot of material that is in the public domain you have shared very little of substance of your own.

He has consistantly shown what, why and how of every thing he has done.

.

Now Teezee, I hope you just wrote that last post out of anger, and don't really mean what you wrote....

ME "stealing" Thomas's ideas...

WHAT IDEAS WOULD THAT BE?

(I can't find an emoticon on this site that conveys how I feel at that statement)

I have been to saigon. I have seen FIRST HAND what they do, and how they do business.

Erm.... Have you ever seen a fake rolex watch from anywhere other than China or VIETNAM?

We got off to a bad start, but lately I was under the impression that we had all "left our ego's at the door".

Clearly not!

teezee, please post All "Thomas's" planned specs (port angles, heights, pipe dimesions etc)

I'll tell you who (most likely) designed them.

This is the same guy who had the ignition too advanced, and the main jet too rich, as well as the exhaust port timing totally up the cock yet he is able
to come back from Vietnam (a place that over the last few years (in the Vespa tuning scene) has gained a well deserved reputation for stealing OUR designs, remaking them (exhausts, cylinders) and selling them for half the price!), and when he returned, he MIRACULOUSLY knew all about it (but he was just keeping that "hush hush")

teezee, if you think I have learned ANYTHING from your thread (other than the Saigon stealing machine has hit godzone) then mate, you are sadly mistaken.

I have given you some real gems on what directions you should be heading in (primary compression,scavenge patterns,compression ratios,transfer shrouding,ignition timing)

I am bitterly dissapointed with your attitude now Teezee.

ME stealing Thomas's ideas indeed. (again, WHAT IDEAS?)

Your arrogance knows no bounds.

It was myself who had the bike setup like this. I told him what I wanted, he did suggest things that I didn't understand or was to impatent to be bothered with at the time and in the end the customer, "me", is allways right, right!

You realy are behaving badly. Please continue to leave your ego at the door.

This is Thomas a Vietnamese race mechanic, you know that place where they have all those hot 50's and 125's are big bikes.

Thomas, ESE's Race Team's Tuner is fettling number 9. adjusting the port timing for Taupo.

Its hard to see but he has taped a degree wheel to the magneto flywheel so he can mark out the exhaust port height he wants.

None of this raise the port 3.5mm for a gazillion HP nonsense. He knows what timing he needs and sets the crank position there before marking the port and then doing the hells death port job that we all dream of.

You should see him setting up a carb. Talk about pain staking, he starts with a main jet so big the bike floods at about half throttle (apparently this proves the oriface of the needle/needle jet combo is big enough) and then he slowly step by step works back until it runs clean.

Most people start at the bottom with a carb and work up, He starts at the top and works backwards.

Never seen him blow one up. But then he is intelligent with the throttle and does not ring its neck when the engine is in distress.

Boy o Boy am I Looking forward to Taupo.

.

Oh, sorry for the confusion. Don't take this the wrong way Teezee, but you would see it the same as me if I was stealing your ideas (well, not only mine, but more your friends and peers in the industry.) I don't aim this at YOU (or even Thomas) but just think about the reality of the situation.

This particular subject is very raw in the industry I work in. (It get discussed over here ALOT!)

Europe.

Vietnam.

[TZ350]

Yes you are probably right, we don't live in Europe so don't realy know how it is.

I have worked with a lot of people in my time and Tomas is one of those people you just have to admire. One does not meet to many of those in life.

Yes you have put out some gems, I am sure Tomas is glad that at least I got the idea eventualy.

You have to respect Tomas for being able take (put up with) my ideas and build something that didn't immediatly blow up.

Like I say, nothing personal against you or Thomas.

There are some really nice guys (some of whom work for companies like KTM and Huskvarna) over here that have had their designs copied "over there" (including one guy who named the exhaust after his son (Franz)), and sold them well, only to find that they where later offered on Ebay for €180...with the same Brand name!

There are dozens of stories like that, but PLEASE remember that the techniques you are now using where developed people in this part of the world..... I know that for a fact.

Does Vietnam have a factory 125GP team?

No.

I hope we can end this childish shit now!

[speedpro]

I think we might need to make a list of the countries with people who may be able to think of a way of making a small 2-stroke go faster plus a list of people who definitely can do that, and where they live. We can then reliably slag anyone else's ideas and also accuse them of nicking the above mentioned list of peoples original ideas. Me personally I paid Wobbly to design my motor but I'm not sure where he got the ideas from, someone in Europe probably. I'm gonna ask him.

[Kickaha]

You realy are behaving badly. Please continue to leave your ego at the door.

He's always behaved badly, imagine riding a bucket two up through Otira gorge the filthy law breaker

As regards his two stroke tuning ideas the fiddler would have taught him everything he knows

[Buckets4Me]

Does Vietnam have a factory 125GP team?

No.

I hope we can end this childish shit now!

no but the CHINES do. Did they steal that from APRILLA DERBIE ?????



you make a design that works people coppie it how the world goes
you cant tell me the GERMANS never coppied anything ???



just ask the AMERICANS they steel everything patten it and call it there own
how the hell did they get to the moon ???????? stole it all
Russians did the same thing

now stop sulking and get on with making MY engine faster
(and I dont care where you steel the idears from) just dont ask me to pay for them. This is buckets after all

[Buckets4Me]

He stole them from ME!!!!!!!!!

now pay up please

1 mILLion DOllars.
or I set minime onto you

[TZ350]

I hope we can end this childish shit now!

The techniques being used now look remarkably like those in the Yamaha SAE paper from about 1990 I posted earlier and the examination of some cylinders, Suzuki RM125 and Honda RS125 being two of them, all this information I have posted as I have gone along.

As for the childish shit, any time you want to bring some maturity to this thread it would be welcome.

Speedpro you are being subtle again, I can tell!

When I worked at the same place as him for a while, I was going to ask, but then I noticed the extensive libary. Any way to ask would have only invited a crack from one of Waynes walking sticks.

That bike he built at Buckleys did run at Top International GP level, it was built from the ground up and started with a clean sheet of paper, yep it was a Wobbly design for sure.

.

Are you sure about that?

It failed to qualify at most of the rounds and was slower than the top NZ Superbikes
