HELP!! I have a 2004 SV1000, it has recently started to make a strange and expensive sounding noise. If I accelerate hard then come off the throttle there is the sound of metal grinding somewhere down by my left foot. The same occurs if I come down through the gearbox and the revs are kept up etc. It seems worse when the engine is cold.
I've done about 15000 miles on it and generally kept iot in good nick!
