Hi all,
Just recently bought a 2014 g650gs Sertao w/4400 miles on it from a private seller. Ran great when I checked it out. Ran great for about 100 miles, then I noticed it surging a bit and idling erratically--varies between about 1,000 and 2,200 rpm when sitting at a stop. A few times I've downshifted and gone into corners in 3rd or 4th and it just loses all power, then takes off. I've done quite a bit of online reading and researching over the past few weeks and I'm seeing others with these single cylinder bikes having similar issues, with all sorts of recommendations on fixes. Everything from starting procedure (no throttle, wait for all lights to go out, hold button in for three seconds -- I've been doing this), turning on key, not starting, open throttle up and close twice, disconnecting battery for awhile to reset the ecu (did this, left it unhooked for about an hour), changing to extended tips iridium plugs (I've worked on older 80's Japanese bikes, this is my first "new" bike and this process seems kind of complex and made moreso by the lack of repair manuals for this bike. I also have stumbled across info about a recall on these bikes for stalling issues--the fix is a software update, but I've read a number of folks who've said this didn't solve their issue. Anyway, I wound up taking to my BMW dealer, fifty miles away, for a state inspection and check over. The software now at the current version, and they thought that wire routing for some aftermarket Denali driving lights was interfering with the throttle rotor. Picked the bike up, rode it about a hundred miles without issue, the next day went for a ride and it started doing the same thing again.
Is this just a quirk of these bikes that I have to live with or does anyone have any thoughts on what else might be going on here? Very frustrating to buy my first modern bike and be dealing with issues right out of the gate on a bike with such low mileage. Thanks in advance for any thoughts/advice.
