My 955's been running great since I got all the tank and fuel delivery problems ironed out (mostly thanks to DeCosse), which was about 8 months ago. Was in the garage, hadn't ridden in a couple of weeks--I do keep a batt tender connected. Went out for a ride with a nephew and at a stoplight a few miles into it, the idle got rough, and I had to rev a bit to keep from stalling out. Had no noticeable problems at speed, just the rough idle, and an intermittent noise, not a knock or a tick, but something in between, like one of the cylinders was misfiring. Figured I'd throw this up here and get some of the pros opinions before I take of the tank and dig in. I've yet to even hook up tune ecu to see if it can tell me anything.
