Hi people I've recently bought a used 23 plate RSS 125 1k on the clock, I've now added a further 600 miles in a month. So this morning whilst getting it ready for work it would not start, the temperature gauge was flashing on a cold engine. No fuel priming or attempting to turn over. Any clues people? Some background Other day on the carriageway it cut out but came back on then yesterday did the same, found battery terminal had become loose. Nipped up and it was fine. Rode home and it was fine until this morning. No fault codes stored on the on board diagnostics.
