this is a recent development on my wee, which does have 98,000 miles on the FI system. when I decelerate fast, or sometimes just dry revving it and let off the throttle the rpm's will dip well below the idle point, down to like 200 rpm's then settle back up at 1100 rpms, this is also accompanied by the bike sputtering at high rpm pulls to redline when under load. it was really noticeable when trying to loose my tail on angeles crest highway friday... (my friend's bmw 355is) perhaps I was flogging my little wee a little hard... since i've never taken those corners at 80+mph before, and topping the bike out at 115mph indicated in the straights. also, for the first time ever I noticed the rubber on my bt023's being pulled off the tire in little rubber balls ( i've seen this on sports bike tires but never on this style of tire)
