Well my '05 V-Strom does it on deceleration some, the '04 Intruder 1500LC does it and it can get really bad on deceleration, "J"s '07 Shadow 750 does it some on deceleration.
I thought something was wrong with mine too. Then someone told me that if it starts to do it and you are able to put one hand on it and it goes away then it is fine.
I don't take both my hands off mine anymore.
