ESE's works engine tuner

I believe that in an earlier post somewhere in this thread u quoted thomas as saying that 26 was the maximum HP for an air-cooled engine.
Must be satisfying getting such good figures after all the hard work you guys have put in, well done!!

TeeZee's bike.......

Thomas has cured the clutch slip and they are now getting 27+hp from an aircooled 125 with a legal 24mm carb.

Three Times Past.......


Fuel Fog appears in the bellmouth of TeeZee's carb as the engine gets up on the pipe.

Can those that said three times past does not happen explain where this fuel mist in the bell mouth comes from when the engine is up on the pipe if the air mass is not moving back and forth in the inlet tract and passing the main jet at least three times like TeeZee explaind it would on a well tuned bike.

so is the MNZ ok for 125 two stroke in the GP to run 28 and 30mm carbs with 24mm spacers,as a well set up TS125 with this carb set up will make 24-26 hp and have a shit load of mid power,know a racer who wants to build one,its going to make it hard for the 4 strokes.TS125 with a normal 24mm carb would not rev much more than 11000 rpm.

Now that is looking rather fecking impressive. Man you guys are killing us 4 stroke boys. I have managed to get some time off work tomorrow to take the new engine to the dyno. I will let you no what happens.

I am looking forward to seeing your dyno graph, we might be winning the dyno wars but we know it takes more than that to win races, its about the whole package........... so we are not feeling to smug.

all they need to do now is ride harder
cant wait to see how your bike compares

I'm picking bitter disappointment followed by a decision to go 2-stroke, eh?

Yes we are pretty pleased, and all that copper for cooling is not looking so stuped now is it!!! .........

Insert witty comeback here ..........

Any guesses where the manufacturer measures the size of this...........

Venturi Flow Tube

I think that if I use a 24mm design like this, but with a main jet setup like a Gardner carburettor instead of an injector I could push the GP to over 30hp.

Gardner Carb

When I think about it a 38mm carb could be modified with one of these so the narrowest part of the 24mm venturi is where the manufacturer originally sized their old carb.

So all legal by the definitions I have seen posted lately.

That to be legal a modified carb has to be measured at the same place the manufacturer originaly did.

FXR's are great and they are the bike to beat at Mt Welly and they have brought many new people into the sport and thats very good but if you want something special you still have to make it yourself, and I imagin thats what the old style spirt of Buckets was about.

Maybe Walter Kaaden was onto something with disc valves. . .

24mm legal carb

After Taupo I am going to enjoy getting started on my new carb. Its going to be of the slide type and the minimum dia of the flow tube will be positioned at the same place as the manufacturer originaly sized their carb


The concept
The parts

Press the Venturi Flow Tube back to the manufactures original measuring point

Perfectly legal (by anyones standards) 40/24mm high flow carb


A legal 24mm carb, as its measured at the same point as the original manufacturer did.........

Instead of restricting carb sizes or mods and therfore stifling inventiveness, the more effective way might be to limit the HP allowed to say 20 and top placing bikes are dynoed.

[speedpro]

Think you'll have it sorted by TRRS 2011??

[TZ350]

Think you'll have it sorted by TRRS 2011??

Yep..........

it's only a carb this time

not a new frame bike engine and carb

Looks good to me.
