Posted April 11, 200817 yr just had the mrs,s R6 in the dealers because i noticed a high pitched whining noise coming from the ecu they said its perfectly normal but im not so sure. if you turn the ignition on,dont start the engine, then wait for the fuel pump to stop whizzing and wirring then put your head down near the seat you can hear it.they reckon to have tried one they had in the shop and it did the same but ive never heard it before and shes had the bike 2 years.Anybody else heard this?
