Issue after filling up with 650GT

[Rifleman3006]

Not sure if anyone has had a similar issue but would appreciate all feedback. I filled up with Premium (same as always) but noticed the bike was acting funny after riding about 7 - 8 miles. It began to idle faster and frankly engine sounds more raspy/throaty. I noticed after coming to a stop sign that my brakes weren't as effective as the higher idling was wanting to push the bike forward. It felt the same way at 2 additional stops on he way to my garage. I can't believe this had something to do with refueling but thought I would mention it. Any ideas would be appreciated. Bike is a 2014 with 7700 miles.

Best.

Had a similar thing happen to me a couple of weeks ago. Hot day, mid 90's, 10-12 highway miles, stop for drink, start, and won't idle below 3k. got home, sat overnight, not a problem since. I do ride everyday. Not fuel related in my mind, although last time I was in the shop 9BMW dealer) the service mgr made a point to tell me not to use fuel over 91 octane. Something about carbon deposits. I've dropped down from 93 octane, and cant tell any difference.

I don't know what it is, but don't think it's heat related either.Summertime here is regularly over 100 degrees. I commute about 8 miles each way and have yet to have an issue like that in almost 2 years, 8600 miles. Nor have I had that type of issue on any of my other pleasure rides.

Same here, hot weather too. I use 93 octane in fact I go once in a while to a station that sells the stuff without that damnable alcohol in it. Cost more but the bike sure likes it better. I do add a bit of fuel additive every couple tankfuls. Star Brite enzyme stuff seems to make things operate better, less low speed surge, smoother operation, better idle. If you live in a state run by idiots like I do that make ethanol mandatory for most uses it's a pity because this bike just doesn't like the stuff much. They don't have to deal with this crap in Europe and Asia so their engines aren't really designed to handle the lousy stuff we get. One serious problem with ethanol is that it's highly hygroscopic it will hold water so what's going through your fuel system has a good bit of water in it. Corrosion is a problem but the change in burning characteristics is worse. It's more of a problem with small engines than larger auto and truck power plants. If the EPA manages to get the ethanol upped to E15 from E10 in our fuel there will definitely be more problems especially for bikes.

Thanks guys. I took it out for a spin today and it ran like it's brand new - go figure?? Will keep an eye on it and see if it happens again.

Amen. My Scoot has not ever had fuel with Ethanol added. Clear fuel seems to be available from more Oregon cities.

Yeah, you can find it there are two stations with real gas not too far from me here but the price is about half a buck more per gallon. With E10 you get about ten percent less power and mileage than with the real stuff due to the lower BTU content. Not to mention the corrosion problems that can occur. But it makes the corn growers happy.
