ESE's works engine tuner

[TZ350]

aim the open area of the plug at the exhaust port. So the earth strap face it towards the transfer

Ok thanks, I have a collection of indexing washers and will try it.

Ok. Chambers and I have put our money down on two of these 2-Stroke EFI kits.

From:- http://www.ecotrons.com/2_Stroke_Sma...e_EFI_kit.html

I asked quite a few questions (that Flettner suggested) before buying it and the supplier always came back with good meaningful information, ie they look like they know what they are talking about.

Giggles has a 4-Stroke version for his new bike and I think its the same as the one Sketchy has on his supercharged 100.

Team ESE have used conventional carbs, then pumper carbs, now fuel injection could be the new thing.

I am not sure, but if we can get them working, these could be the first EFI 2-Stroke Buckets, anyway it will be lots of fun playing with them ....

Looks interesting.

You could make yourself a nice plunger throttle right next to your disk valve for a nice short inlet tract and then inject into the cases. Also means that you aren't putting fuel through the same restrictor as your air. I don't know what atomisation/ dispersion of fuel would be like though...

Also where do you put your map sensor? in the cases? Can you just tune off of tps and rpm alone?

I don't know, but this is where we have fun finding out.

You tested a EI carb as well too albeit very briefly..........

Yes, actually two, not enough old style needles available to get the blue one working properly. But Giggles later model one worked well on his FXR.

.... could be a race for the first 2-stroke....

but you might find some interesting information in here (I think I posted this up a while back):

. Like so:

[136kg136ps]

Frits,could that be configured as to change the inlet timing?It would seem that if mounted perpendicular to the crank rotation that one could not only have it as a carb slide but also to change inlet timing.Maybe it was mentioned somewhere and I missed it?

You would have to controll all clearances meticulously, but it could indeed be done.

[Moooools]

. Like so:

More like so:

Only problem is massive amounts of sticktion due to the pressure drop across it. Could be solved with careful implinentation of a little cam.

[wobbly]

So now we will have a GP125 on EFI, with a trick variable computer controlled intake sytem as well, that, oh shit, still detoes in the overev - WTF.
I know that's sarcastic bullshit from me that doesn't help at all, but surely the extra effort needs to be spent sorting the known basic issues, before flying off on another tangent - what happened to the super duper stinger bleed idea for example ,etc etc.

BTW I tried the plug indexing idea on a TM125 engine that won 3 straight kart titles with 50 odd Hp at the sprocket, rotating the bronze insert to any position made no difference, changing plugs saw up to 2 Hp changes.
A crap wasted spark ignition with insufficient burn period or whatever may be a benefit in the big ski engines,as it does in the big 4T engines with horrendously shaped combustion chambers, but with a DC CDI ECU , and a toroid ,all these
negative details go out the widow.
Then if you have some issue like heinously rich allky mixtures,using twin fire CDI / Crane super coils - make all problems regarding ignition power irrelevant.

Post a video and dyno run of your daddy's latest abandoned project ...

Mocking is easy, and as SS90 has shown, you don't need many smarts to be negative.

[husaberg]

. Like so:

bump Gardner carb

As interesting as this TZ

Even with the fuel oil mix?

I don't think he was mocking, maybe a little blunt but...........................
