I've had my 950A since March 09, I ride all year round and have clocked up about 22000 with only one problem. The lights went on the bike and it turned out to be a corroded wiring loom which had been sat in a pool of salty water. Yamaha replaced it with no problem but stated they had never come across this before. Seems to me a design flaw if water has no where to run. Anybody had this problem and found a work round solution. If it's happened once it will happen again especialy in winter when the hose pipe is always out.
