haven't ignored you but have come totally out of retirement, working (as i say to the wife) 27 hours a day 9 days a week. i cant tell a lot from your picture but if its the anti rotation bracket that fixes to the frame then i would guess that if its out of true it could give you a noise.
please take it back to the dealer and demand a repair or replacement you should not accept shoddy goods in exchange for your hard earned cash,i have just had to buy a new car to keep mileage of the camper, its been back once in the two weeks since i bought it to have a list of small niggles put right,and i am now making a new list i don't care how many times i go back i will end up with every small detail as it should be.
oh dear, yes that is my hair in the way....dealer away at the moment, but will
talk to him , although I have been offered my cash back...the bike is such fun, and nippy, and illeagall...22 mph my partner said as he drove behind me the other day....oops
