Fired the bike up to take a parcel to the Hermes collection point. ECU reports a rear bulb out. I thought it was telling porkies as all seemed to be working fine, then remembered there is a number plate light. This was, indeed, lacking lumens. Thinking that it would need to be changed some time before September 2019 for the bike's first MOT I decided to ignore it, apart from giving the housing a whack. Lumens returned. I'm a maintenance god. Bloody unreliable BMW piles of shit. I am going to write a letter in green ink. Parcel was dropped off. This happened to be a Texaco garage and 15 litres of their finest unleaded fell into my tank so I decided to use up some as the bike would be far to heavy to put back in the garage. Quite balmy at 10.5C and did not need the heated grips or Keis jacket powered up. Roads were wet & slimey from earlier rain but aren't modern tyres fantastic?
