Came out to garage this morning . Switch on fuel pump primed ,hit starter . Nothing just the front lights dimming . No clicking etc bumped it off first time no issue at all . Ride out came back and same again . Priming and Dim lights . Am thinking it’s battery related . I have 12.1 V showing across the battery but nothing . Got to wait until neighbour comes back back to bump it off again and get a reading when running . Wanted to check to see if I should be looking elsewhere but battery
