ESE's works engine tuner

Are you sure about that?

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

I know in real terms it was not that great. Did it qualify at any round??? But it was up there, and it was a game effort.

It finished 18th at the Spanish GP in 99, but missed qualifying at 3 out of the first 4 races it entered

Because the future may be 100cc I am starting to research it. Converting a RG150 water cooled to a 100cc, I have heard people say they had problems with the transfers and I suspect the problem was port/duct velocity.

From the Porting School:-

"So what we can say at this point is that a significant proportion of an engines flow through depends on port velocity as well as the generation and utilization of pressure pulses. This means even a little excess in terms of port area can hurt power even though it may, on the flow bench at least, flow better."

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

Oh, there is more than the Otira Gorge (some secrets we never told!)....you filthy GP engine stealing "GO CARTER"

As for Fiddlers lessons, my favourite classes of his where

"catching a ride down Manchester street on a Range Rover"

and (my second fave)

"Love thy Neighbour"

GN125R indeed!

Now, go change some tyres!

[SS90]

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.

Quite right speedpro, and certainly so much of the technology that the Japanese developed is being used today (as, in reality, the Japanese have stopped developing two strokes)

However, my point is that (rather than going through all my posts, to prove it) Thomas come back from Nam, and all of a sudden, Teezee starts "coming up with all these good ideas (I mentioned months ago "look at Japanese 125cc cylinders", and months ago, Teezee asked me "for clearer hints", and only last week, I told him "Honda RS125"

Lately, I even posted pictures of my latest work.

Basically, Logically, realistically, this level of two stroke tuning DID NOT COME FROM VIETNAM...it's all stuff I have mentioned here prevoiusly, then, all of a sudden I am "stealing Thomas's ideas"

WHAT IDEAS TEEZEE?

A peaky, high exhaust port duration, over advanced, too rich, incorrect primary compression rato'd, shrouded transfered,not retarding ignition two stroke with an exhaust design than was on the Millenium Falcon?


Naaa, Been there, done that. Years ago.


I am 100% confident that Wobbly will not say " Oh yea, we learned all our knowledge from Vietnam"

Think about it.

if Thomas knew what you are now posting in NOVEMBER of last year, he would not have built the peaky shit box he did before I started posting

[Chambers]

SS90 there is something disturbingly odd about you.

[SS90]

Ok. I was at Johns to dyno the bikes and yours turned out to be the best!!!! OK. and mine was the worst.

All four bikes were run up and it turned out that the more Hotted-Up they were the worse they performed.


As the testing went on there were a few more surprises.

Many thanks to John for his time and help.

Really? I can't believe it!

I have watched the posts with interest. I have seen SS90 push crankcase compresion ratios and hint at the more modern way to the point of being overbearing, with a bit of a "bee in the bonnet" hysteria.

TZ has followed up and done his own research, sharing the results with us all the way. Who knows where TZ found Tomas but you can bet there were more people than just Wobbly working on the BSL project.

Hmmm, I'm not 100% sure what you point is there, and this really has gone out of control.

I have given quite a few good hints here, and, in my opinion (and others) Teezee is giving Thomas all the credit (not that I did all that in the pursuit of glory), I just read some very wrong information and was offering advise (correct advise) based on experience.

Now I'm being accused of "stealing Thomas's ideas"

What Ideas?

Did that when I was 15. (as have so many people before me)

Actualy your input has never been more than reciting the basics and some vague hints. I expect that TZ in asking for clearer hints was just trying to draw you out to see if you actually had any real "stuff" to offer.

As for your pictures, cutting gully ports in a barrel is mentioned in Jennings book and probably Bells too.

You can't claim ".it's all stuff I have mentioned here prevoiusly," as you have not actualy mentioned anything of substance like TZ has, your hints are just that hints, vauge things that can be used later, for "I told you so" or "That was my idea".

TZ's done the research, your just trying for the glory.

And, pray tell good fellow, what have YOU offered this thread?

Because, of course, you knew it all didn't you.

Because you think a A peaky, high exhaust port duration, over advanced, too rich, incorrect primary compression rato'd, shrouded transfered,not retarding ignition two stroke with an exhaust design than was on the Millenium Falcon

is a good engine huh?

[speedpro]

As clever as TZ is, he has been avoiding a few of the basics, like a good ignition and doing a few dyno runs. That has changed now which will only bring bad news for the rest of us. In attempts to gain power a few of us have headed down the blind alley of making ports bigger etc. TZ is taking a more considered approach, one which it's taken me a few years to cotton on to. Hopefully he will be too old to ride it properly once it is all sorted.

SS90 you have posted the above three times on this page, why do you need to do that. What has TZ done to you, that you need to react so badly? Its OK that he is posting usefull stuff, get over it.

[Virago]

The Mods don't like to step into such worthwhile technical threads, but this is getting a bit silly.

Can everyone please move on from this childish bickering.

Cheers.

Yep I am pretty convinced about dyno's now for sure. We just didn't get around to building one at work as quick as I hoped, it all just takes so much time. I am lucky to have Tomas's help with getting things done on the bike, now that he is back we should start getting somewhere.
