    Intermittent FZR spark

    Hi Guys,

    I went to start my FZR prior to a ride (it hadnt been started for a week) and although it would crank, it just wouldnt start. I checked for fuel pressure and checked all the plugs for gap and colour etc and all was good. I then checked for spark and the spark seems to be very intermittent and when it does happen it seems weak, all cylinders. Battery voltage is a solid 12 volts. The ski is 35 hours old.

    Has anyone had anything similar ?

    Had similar issues on my fzr after sitting. Found enough corrosion in the plug boot that the spark was jumping out of the plug at the top and down the side of the porcelain to the hex of the plug body. I could see black marks where it was jumping, new plugs would work a couple times then fade out. Cleaned the booys out and put a bit of die electric grease around the top of the plug botot where it meets the valve cover. I'm about to install my 3rd set of plugs in 67 hours just to be sure.

    Are you sure you don't have the lock enabled from the key fob? Just hit "unlock" once to be sure.

    The ski won't even crank if it is locked.
