While I was out last evening riding my '05 Adventure and enjoying the beautiful summer afternoon, I heard some horrible noises. I was in 5th gear on a quiet back road and caught up with a slower car (aren't they all) I thought that I would be lazy and just roll on the power to pass witghout changing down a gear or two. As I said I was in 5th at around 3000rpm and rolled on the throttle to pass and the rattle/pinging was shocking. Before you ask I run 95 octane quality fuel from a major quality supplier and I ride the bike every day.
The bike has 16500km and has its 10000km service done by the BMW dealer. My question , has anyone else noticed this on their bike.(twin spark model). Is this caused by timing out or something to do with the polution control system? Could my dealer not have checked the timing or is it possible something could have slipped out of adjustment?
I await your collective wisdom
