went for a spin last week,and on returning,after a cuppa and a fag ,couldn't start the bike.had to go to work,so thought i could sort it on my day off.i got a call at work from the ball and chain to say the bike's been blown over by the wind,no shed ,however when i got home and picked it up,no damage as it was covered,it started first kick,and has done so ever since.i will still strip the carbs for a look.i had been turning off the fuel tap but ever since i leave it on,and no problems starting since!!Ideas?
