Today started really well. I brimmed the tank and covered 88 miles before I needed reserve. Back home for lunch & chores and then to the petrol station for the afternoon ride. Filling the tank again revealed the bike had achieved 62 mpg with mixed riding, I’m happy with that.
The afternoon ride lasted about a float bowl’s worth of fuel before it was obvious that something was very wrong. A slight misfire quickly followed by really heavy pinking and smoke billowing out of the exhausts. I pulled over, catastrophic head gasket failure was my first thought but the smoke smelt odd…I’d filled it with diesel!
I wasn’t far from my local pub and with help from friends we drained the float bowls and fuel tank leaving a small amount of inaccessible diesel still in the tank. I pushed the bike back to the petrol station and filled up with the correct fuel, after many tickles and kicks it started but with lots of smoke. Eventually this died down and after a few test rides it seemed that all was well again.
I can’t believe that I’ve been this stupid, my only excuse is that the premium unleaded and diesel pumps are next to each other and habit took over (I have diesel car). I’ll be out again tomorrow so I’ll see how that goes. I do hope the Triumph Gods are smiling upon me.
