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.
