Question about race fuel ????
Dutch-K5 Fan:
In holland you get 95 or 98 octane at the pump.
Never had any isseu with one or feld a performance advance on a k5, rm125 or a rmz250.
Could be europe is different. Some buddy's do use avgas, 1/3 avgas 2/3 pump.

My 03 doesn't seem to like 93 too much, so I have been running it on VP unleaded StreetBlaze 100.

Hi Dutch,
Do you have any idea of how the fuel that we have now in europe affects the jetting? Example, my K5 is from -89. Should I in genaral increase the size by 5% compared with how it was in 89 due to unlead and Ethanol? Any idea?

Hi Peter. I was looking for some info of fuel in Sweden. And I'm interested in diesel race fuel, so there for a late respons.
I don't think there's a jetting issue with the unleaded fuel maybe a different head design/squeeze.
With the ethanol could be richer. I looked for water injection with diesel. Methanol is used with this in cars. And by that way that with speedway they use methanol. And twice as rich than normal unlead fuel.
Do know the fuel in Europe is better then the US.
