e10 fuel and squish?
 

In search for some more fuel range rather than power/torque.
Is 1.3mm still target squish for the 300 (2011) with e10 or does it have much effect?
I'm in the UK, sportman/clubman pace and sea level to 600m, most readily available fuel is 95 Ron 10% ethanol. Current squish is 1.9mm with the piston 1mm above exhaust port at bdc.

I've set floats and running nedw needle 2hrs can sometimes be a struggle but bike is on its side a lot lol.

1.9mm is large. Going down to 1.3 will make a noticeable positive difference. I am not sure about the E10 fuel compatibility.

I run 1mm squish but with the ebowl opened up for approx 13:1 static compression. E10 works fine
