Rode my 2006 GT on a 700 mile trip last week. Last 300 miles from St Louis it was 40 degrees. The last 25 miles were back roads after the interstate. On the exit ramp the bike started acting strangely, the slightest roll-off of throttle would immediately stop all fuel and the bike would just feel like an anchor was thrown out, a lot more than normal (I have put 41,000 miles on it). The rest of the way home the slightest decrease in amount of throttle would just drop the revs and cause the boat anchor sensation - there was no partial throttle situation possible. Was worst below 4000 in lower gears.
I had some of the BBS early in ownership but never changed the airbox or had new software loaded. For the most part it always ran well. I have not ridden it since Friday to see if its still doing it.
Any ideas? It's like 250 miles on cruise in the cold did something to it.
