My bike when water had built up in the tank/carb, farted and spluttered and I could hardly rev the thing. Mine also happened after I had gone onto reserve tank, and picked up the rubbish from what lies beneath. It might be worth collecting the drained fuel, to see if water is present, water in carb may mean water in tank. Also clean or replace spark plug, after you've finished with the fuel. hope this hopes or at least is a starting point. ken Link to comment Share on other sites More sharing options...
