Good weather today so took the bike out for a run and noticed condensation inside the speedo glass, thought it might disappear with the heat from the bike but it's still there. Looks like a trip to the dealer tomorrow to check it with them, just wondered if anyone else has had same issue?
Thanks Crispey I will have a further search through. I have found a Captain Rambunctious You Tube entry with a similar problem on his Thruxton where he had the instrument pod replaced under warranty.
Update on the "condensation", as usual very helpful at the dealer and apparently I'm not the first to go back with this problem. Photographs were taken to be logged with Triumph along with VIN, registration and mileage which should result in an updated speedo unit. Whilst I was there I ordered a sump plate (in black of course) which they will fit when replacing the speedo.
