ESE's works engine tuner

Thanks for the EngMod2T carb dimensions and photos, very usefull.

Malaysia and Thailand are still not that easy to get too 13-14 hours flying time. I once had a good look around Bangkok for suitable engines, I got a few carburettors but there was not much engine stuff to be found and I found it hard to organise shipping anyway. Thomas was back home in Veitnam recently and he found the same thing. You would think there would be wrecker yards full of them but something happens to the old bikes, they just seem to dissapear.

is there not some kind of thai/malay version of ebay/trademe?

[TZ350]

I just had a look at a world map, London is on the opposite side of the world to us and Thailand and Malaysia are nearly half way there, so they are half way around the world from us, so not exactly next door, in fact your about as close as we are.


1920's map of the British Empire

There was a time when the sun never set on the British empire.



Countries that still have the Queen of England as Head of State.



Now we are one of the very few remaining self governing former colonies that still has the Queen as head of state,

Lady Gaga is presented to the Queen.

and as we are those Islands in the bottom right hand corner of the map we are about as far away from Britain or anywhere else as you can get, except for maybe the South Pole and Happy Feet the penguin.

Yes there is the problem we have is a lot of traders don't want to go to the hassle of shipping overseas.
ESP with heavy things like engines.
There is a available in the Asian countries called the Nova Dash 125 it is water cooled Crankcase Reed engine 2 stroke 6 speed but according to Matt at Tyga it is unsexy in the internals it also has a 52mm stroke and no power valve, I do wonder if another cylinder could be added, But it did look promising though. The engine that is. The Nova Dash has now became a boring old Four stroke.

The bucket racer in the pic looks promising - looks like you could drop RS125 'glass straight on.

Whoever perforated the front disc went a tad far though IMO.....

[2T Institute]

Buckets is about using as little as brake as possible.

That asian bike is obviously trying to keep the tire friction/drag down as well
Much like these fellows

One very much like this does
the standing Quarter in 11.3 seconds

Nova Dash sprinter from here.http://nsr-world.com/weird/

The custom ported cylinder is bored out to a little over 160cc and fitted with a Wiseco single ring piston. Fuelling is by an open 38mm (yes 38mm!!) RS125 Keihin, and the expansion chamber is hand made stainless steel based heavily on an A-kit RS125 system. Silencing is sort of taken care of by a kevlar stinger! These little drag bikes are all about screaming motors and light weight, just look at the holes drilled throughout the frame! The usual pressed steel swing-arm has been replaced with a custom alloy unit too. The stock Dash peaks at 7000rpm, this little screamer revs on to 12,000rpm utilising an adjustable ignition unit. Although these bikes are never dyno'd, their performance figures are outstanding... this particular bike covers a standing quarter mile in just 11.3 seconds! Not bad for a "girly shopping" bike!!!

[dinamik2t]

Yes, (honda) dash is the watercooled one! I thiink they mostly fit in CR/NSR cylinders there..

There is also Modenas Dinamik 120 (which is a Kawasaki). That's aircooled and 54X51.8 . 14mm wrist pin, not much "125s" pistons to fit..
Parts diagram: http://users.uoa.gr/~sph0800108/mode...s-OneHalfR.pdf

And Yamaha 125Z/ZR, aircooled and 53.8X54.7 . 16mm wrist-pin, large variety of pistons to fit.

None of the two has powervalves though.

Not on so much on kart tracks.

I reckon the same rules apply on Kart, and big tracks. If you aren't on the breaks best be getting on the gas.

[breezy]

bsa bantam grafting on rgv barrel. bucket style. still a fair way to go!!

[TZ350]

BSA Bantam, RGV, very interesting combo .... what are you building, tell us more ......

[Grumph]

Is that legal for Formula bantam ? Out here you'd build it up aircooled for Classic racing - and run it on Methanol.....

You're still limited by the 'box ratios though aren't you ?

[husaberg]

BSA Bantam with a RGV top end is an EGGcellent idea

A couple more for the pot.
It looks like these owe a little to the MB/H series

Although one of them at least looks crankcase reed.

Question for Frits

What happens at Aprillia after 95-96.
Aprilia has won the 125 and 250 gp champs
What does the team concentrate on?
It it on making them more drivable, or testing new combinations?
Lots of Pipe testing?
No doubt all of the above.
what does the development team do in an average day?
