Greetings. My lady is the owner of a 2009 Spyder RS. She took it new off the floor. Has had all recall and TSB work done. has less then 5,000 miles on it and has already started buying all the goodies for it. I just jumped on her Spyder and took it for a ride. I have found that at certain speeds there seems to be a low end rumble/vibration at the start of 4th and 5 gears. This goes away with the increase of speed but being a Goldwing rider with 247,000 miles in the seat Im not sure if this is a normal noise/rumble/vibration for this unit. It almost sounds like the crank is out of balance during a set speed and plays catch up with the rest of the engine and or the computer is not responding fast enough to the throttle? Not knowing this unit it scares me to have her out there on it.. She took it to the dealer at my request and they say its normal.. I say hog wash and look to those that know.. any ideas?
