ESE's works engine tuner

[jasonu]

Yep, buy one of those "Performance Kits" , a few $$$ for the other Bits like reeds, carb and manifold, more $$$ for any of the race exhusts available, slap it all on and your a talented top line Bucket race engine builder I recon.

And most likely you haven't wasted a lot of time and money on failed experimentation and useless parts.

[F5 Dave]

They are marketed as performance parts. Are they competition parts? That is the grey area. I think they are well out of the spirit of the rules, but that is only my feeling. Anyway this has been argued to death several times.

[Henk]

Every time I've seen the debate the spirit of the rules seems to get trumped by the letter of the law.

Yes sir, flash the card, buy the parts, and you still have no fu*#%& idea how it all works, suits some I suppose.

[speedpro]

Works for me.

I get immense enjoyment from getting together with other bucket racers over a few beers to debate all the variables of two stroke tuning and the satisfaction of seeing my efforts on a dyno are worth all the hours spent measuring and filing. Bucket racing is not about what we are prepared to pay for a motor, but more about our collective knowledge, abilities, resources and to develop a class of racing that is both competitive and affordable

are you saying that the ESE GP100 in a RS125 GP frame is a old shitter.it don't know but who is leading the points in A grade.

Sounds like Scatological Sadomasicism to me. F@#$k Yeah

Kel Lent me an old KX125 to look at.



Best as I can tell, squish is 0.85mm

These are the pistons I have been using, (because I have them) but I had never seen the original head before. The squish area in the head is much wider than I expected, it must make the combustion chamber a funny shape.



This is the head shape I use with these pistons. It does not give a lot of squish area, but is a better shape (I hope), It runs with 0.8 squish and 16 deg ignition advance at peak torque.

[TZ350]

Bore 56mm Stroke 50mm

The exhaust port is an unusuall shape with the power valve opening the side ports and a small cutout in the top of the exhaust port window and the piston drops below the port floor at BDC.
