New Commando Owner: First Norton

50th owner here and no EML light on although I have read others have had this but turned out to be minor. My bike went in to Donington earlier this year for it's annual service, now 2800 miles on clock, and as Ash said, they spotted that my head temp sensor was earlier type which they replaced. While you are there ask them to look at the angle of lean on your oil cooler and have it fixed if it hasn't been done already otherwise when you get to the 'spirited riding' stage you might start to see/hear it hit the anniversary fender.
