shawn corey Posted April 12, 2011 Share Posted April 12, 2011 i pulled my 98 FZR600 out today after sitting in the garage for the winter and after i finally got it started i noticed it was missing on one cylinder. i checked all the sparkplug wires for spark and they were fine. i put some new gas in with seafoam and ran the bike at high rpm for a while and still number 3 cylinder isn't firing. i figured out it was number 3 by taking the airbox off and spraying some starting fluid at each carb while it was running. i sprayed each carb individually and the idle wasn't affected when i sprayed number 3. my question is, what should i try next? i figured i'd get some new spark plugs since it's cheap. but if that doesn't work what should i do?

I know you said the spark plugs are fine, but did you try switching #3 out with one of the others? Link to comment Share on other sites More sharing options...
shawn corey Posted April 12, 2011 Author Share Posted April 12, 2011 I know you said the spark plugs are fine, but did you try switching #3 out with one of the others? good call. i'm actually just gonna go buy 4 new spark plugs tomorrow. hopefully it will help but honestly, i've never had a cylinder completely stop firing because a spark plug was bad. usually it seems like they just start running rough before they completely fail.
