fluttering between 3000 and 4000 rpm
I have an '02 K1200RS with 38,135 miles. It started having an intermittent runability issue @ 3000 rpm for the last 1000 miles or so. At times it is hardly noticeable at other times it picks up a terrible misfire but clears up after 4000 rpm. I haven't looked at the spark plugs yet (which I will change when I do a full service next weekend) but it seems like a sensor maybe messing up. I replaced the 02 sensor @ 31,000 miles the bike had no runability issue at that time but my mileage dropped to around 24mpg. Mileage went right back up with new 02 sensor. I haven't seen a post on here with the same problem I'm having this time but I hope someone has seen this and can point me in the right direction. Any input is appreciated.
