My car is 4 weeks old and has only 500 miles on the clock. The nearside top wishbone mount had about 2mm of in and out movement - no wonder I also had the 'clack' on big bumps and some hairy changs of direction when I least expected it. Tightened the top front bush bolt and movement seems to have stopped. Reckon all that V-Twin vibe is undoing things on the quiet.....
Thanks for the very useful check warning folks!
