How nice would high octane gas be?

My 06 Suzuki ran so poorly on E10 that I had to rebuild the carbs (all four of them!) THREE TIMES in 6 thousand miles. This was a bike I bought BRAND NEW. It ate all of the O-rings in the fuel system, ate the petcock so it leaked, corroded the inside of the fuel cap with white powder, clogged the pilot jets over and over again to where the bike would not take part throttle. After the 3rd cleaning I changed all the jets and run non-ethanol fuel. No more problems! Bike is not lean anymore and it actually idled so much higher I had to turn it down 100rpm.
