On the K3 models, Suzuki have addressed the problem. There is a rubber flap behind the radiator which prevents the water entering the spark plug hole for the front cylinder. This was the original problem on the previous models, which just had a rubber grommet to protect the front spark plug( this grommet usually got lost at the first service!). Are you sure that it is still a problem? Because to my knowledge it has not affected any of the new machines, obviously I stand to be shot down in flames
Before taking issue with Suzuki are we sure we still have a problem!
