and yea if service center refuses to change your fander , go to the dealer from which you got the bike , they will help you.
here also the dealer helped me in this and asked them to do it. this dealer is very nice and supportive . one of my friend bought this bike before me and did't checked it properly , after few days he noticed that there is some scratches and paint rip-off from left tappa. he went to the dealer and told them about it. although it was after 4 to 5 days but they changed it with-out any hassle with another tappa from 2nd bike of same color.
