Bike runs the way it should with pure gas. Pretty dramatic improvement. The bike pulls clean from idle right on through now. That said, it’s the only bike I’ve ever owned that has needed ethanol free gas to run properly. How y’all are looking past or “riding around” it, is pretty crazy considering how expensive the bike is. It’s a great bike now, but if I didn’t have access to pure gas the bike would be getting replaced.
You could tune around it reasonably easily, I would think. Not that you should have to. Although I can confirm my wife's Euro 4 spec KTM will do the same thing on corn gas, so it's not just us Honda guys (we try to use pure but sometimes you have to use what's available).
As for those of us that are basically riding around it, and I really don't want to come off as some preachy know it all or anything, engines don't like to be lugged, riding this engine at 3000 in 6th and trying to pin it really isn't much different than driving my cars in top gear at 600 rpm and trying to floor it, or trying it with my 919 at like 1500, it's just something 40 years of operating standard transmissions has taught me not to do. I remember getting yelled at when I was first learning to drive the big diesels for doing it, you can do some real damage lugging.
People in North America in general really like low revs when cruising, though, we've kind of been trained into it over the years, I think.
