ESE's works engine tuner

When was it like that? Circa 1988 it was 95 pump gas max and then it went Av gas when our changeover to unleaded went sideways with sketchy quality. . For a while it said no additives which technically meant 2 stroke oil.

Yes, certainly not in my time. I have heard Fletlander lament the loss of methanol. Maybe I have just heard rumors and imagined it was totally open fuel in the beginning. Anyway I would just love to be able to apply a bit of chemistry to my bucket racing.

Meths was a formula 3,2 etc thing.
Never buckets in my knowledge.

Mike?

Alcohol fuel was only allowed as was supercharging turbo etc with 100cc Four strokes. These were the days of 130cc four strokes and 104cc two stroke, ie pre 125cc ac 24mm carbs.
I have one of the old rule books ACU from the 90's.

I do remember experimenting with methanol in my AC50 bucket racer when I was in the Air Force. Probably because I had it lying around for my other bike. Never raced the bucket with it. I think in the air force days that nobody cared. With the state of tune back then it wasn't needed so as far as I recall there was nobody using it. I hardly knew Neil back then so he might have been. A bit of Methanol for the FZR would be nice although even on petrol it's still tuned reasonably cautiously so currently not required.

fluorine rubber ( fkm in germany also known as viton) has nothing to do with special marine use. Its a rubber with one of the best oil and heat resistance and is used in all ngk rubber spark plug caps and in many sealing rings too...

Thank you for declaring the brochure, as I understood from the first sentence of your post.
But I couldn't quite understand the meaning of the second sentence.
Probably because of a problem with Google translation.…
Well, let's get back to the ignition coils that were discussed.
I have not puzzled over why the manufacturer used this material, which we are discussing, on the spark plug caps. I just needed an ignition coil with two terminals and certain electrical potential characteristics. And I bought it.
From my own practical experience, I can say that I have used this type of elastomer to protect steel parts during coating, in particular chrome plating. Galvanic electrolytes could not destroy the protective covers made of fluoro-rubber for a whole year. There were about thirty chrome plating cycles....
Why is seawater scarier to use than electrolytes?

The composition of Viton may vary depending on the manufacturer and the specific product, but in general, it includes the following components.

....let's turn to the reference books:

Fluorinated rubber, which provides high chemical and thermal stability. This material contains fluorine and other chemical groups that give it certain characteristics.
Seals, fillers, and modifiers that can affect the mechanical and chemical characteristics of the material.
Stabilizers and antioxidants, the main task of which is to prevent degradation of the material under the influence of heat and the environment.
Various additives can be introduced to improve the processing, mechanical properties and other characteristics of Viton.
It is important to note that the specific compositions of Viton may vary from manufacturer to manufacturer and for different products within the same brand.
Viton (FKM) is a group of fluorinated elastomers with different chemical structures, and its operating temperature may vary depending on the specific type of Viton.

Viton (FKM) material has several features that make it popular and valuable in various industrial fields, some of them:

Chemical resistance – the material can withstand aggressive chemical environments, including oils, solvents, acids, alkalis and other chemically active substances.;
Thermal stability – Viton is capable of operating in a wide range of temperatures, both low and high. This allows it to be used in conditions where preservation of sealing and insulating properties at elevated temperatures is required.;
Mechanical strength – the material is resistant to bending, stretching and tearing. This makes it suitable for applications where it is under mechanical stress.;
Oil and fuel resistance is what makes it valuable in the automotive and aviation industries.;
Elasticity – Viton can retain its sealing properties even under compression, bending or stretching;
Radiation resistance – the material is useful for use in the nuclear and aerospace industries;
Insulating properties – Due to its chemical resistance and elasticity, Viton is also used in insulation and sealing products such as gaskets and rubber seals.
Can you name a really strong argument against using this material in spark plug tips???
