Help! My Fazer wants to be a triple

Lift tank off and try trimming the ht lead at the cap end of the dodgy cylinder (only 3or 4 mm needs to be trimmed) you could do all to save you doing it again then replace the cap tightly and spry inside with wd40, put it back on the plug firmly.  it wont be the plug as it only happening in wet suggests its the lead or cap getting wet, also coat all the coil and caps with wd40 when trimmed and dry
bet it dont happen again
