I just went in for my first service (at 500 miles, which is what dealer recommended) and let them know about engine clattering sound on my g5 deluxe, which seems to be most noticeable at mid to high rpms of 2nd gear and low to mid rpms of 3rd gear. like other RE owners, noise does not affect performance, but is annoying as hell on any bike, much less a new one.
When I went to pick the bike up, dealer stated that they think they fixed the problem and that it was due to the heat shield being loose. turned bike on and rode off, and while bike definitely ran smoother after servicing, clattering noise was unfortunately still there.
