I have have a 2014 V 650, with approx 2600 miles. Lately I have been noticing that at times when I give it some throttle, usually when taking off or coasting, that it sputters a bit, like its missing the acceleration for just a second. Any ideas?
What elevation above sea level are you at, and which grade of gasoline with what ethanol % are you using? You can correct the lean stutter which is mostly present at near 2,800 rpm, by rotating your main (lower) throttle sensor counterclockwise by about 1mm... Refer to the green reference mark in front of TPS.
