.060 Over
hate to go against the general consences here, but I think there is possibly something to the tps issue. when my tps acted up in the conditions you mention,kinda coasting along with little or no throttle in 4 or 5th gear,the tps caused my bike to kinda ''hunt'',the fluctuations in rpm caused the driveline to load and unload causing a noise like you describe.once the tps was straightend out the noise was gone.
