NZ$ 2,40 is 1,39 Euro, at that is exactly today's price of regular petrol at the cheapest filling stations over here in Germany. But when we hop over the CZech border, there's an E85 filling station across the street from our test track, where they sell E85 for 0,85 €; that's 0,49 NZ$.

Actually NZD1.48. Sorry Frits. I'm a bit OCD...

Frits, here is your E85 pdf roughly translated.
I've made a couple of changes (eg spark plug instead of candle) but I'm completely stumped by "Rennzweitakter".
I can send you the Word version if you want to make more updates.

E85

It would pay to ask Flettner about E85 as he has run it in his air cooled Kawasaki EFI 350 Big Horn.

From memory the issue is. The bike can be running fine until you put some load on it and with over 75degC head/cylinder temperature you need to enrich E85 to stay away from the dreaded detonation.

He has extensive experience with E85 in air cooled engines.

"Rennzweitakter".

I think it is one of those german compound words they love so much. I think this either means Two stroke motorcycle or racing two stroke

I think its racing two stroke also
i base this on Rennsport being the racing Beemer.
Zweitaktmotor being a two stroke engne

If the Inuits have 100 words for snow the gemans likely have 100 words for sausage.

Thank you for a great job Lodgernz. No need to send the Word version; the PDF will do fine
(Rennzweitakter = racing two-stroke. Renn=run , zwei=two , zweitakt=two-stroke. Who said German is difficult? Never mind, German is difficult. They even say so themselves).

For a base-line to start tuning from, should I use Methanol (Skinny) needles and regular sized needle jets...Or regular needles and large Needle jets. Does the E85 require additional spark advance with normal compression ratios? Does the petrol component cause issues with higher compression ratios?

I'd go with regular needles Daryl. I think you will find the answers to your other questions in the English version of the PDF that Lodgernz posted above.

Don't know what OCD is, but in any case you're right; thanks for pointing it out. I corrected it now.

Thank-you Frits & Lodgernz.

Concise, Sensible Information at last. There is So Much B.S. to sort through, when you venture too far out into the Googleverse!

E85, here I come!

Cheers, Daryl.

Daryl, l had no sucess with a carburetor on E85, not saying it can't be done but I couldn't make it work. Also my Lake injector was less than successful.
For me the answer came with the ability to change over all fueling with the LINK ecu. Up master fuel with head temp. E85 seems to need more fuel as the engine gets hotter, the fuel when vaporized properly (heat) releases extra oxygen, needing more fuel, or so I understand.

Also reeds do not like E85, unless steel I guess. Even carbon V force tell me their reeds will soften with ethanol. Hence one more reason to use steel rotary valve.

PWM Power Jet


Std Power Jet

Maybe some sort of power jet that is active when the engine is hot.

these can be NO normally open or NC normally closed.

It might be possible to do it with a solenoid and simple NO thermal switch that closes when the motor is hot and turns the power jet on for extra fuel.

On one of the Team ESE bikes we have been using one of these thermal switch's (40 deg) to turn on the electric water pump as needed.

For drag racing I would think EFI with Alpha-N mapping would be quite workable.

OK. Back to foundry matters:
What is the stuff that bursts into flame when one sprinkles it on the top of the sprue or riser after pouring alloy?
And where can one buy it in NZ?

Magnesium powder No idea

There's a joint in Oz that appears to cater for the small time foundry man. He might be able to help, although he doesn't show it in his products. I suspect transport safety might be an issue.
