Change Spark Plugs

Hi all,

Have an '07 Red FZ6...About 9,000 trouble free miles....has anyone changed the plugs (recommended @ 8,000 miles) on their FZ? I got the one out on the right side and it looked perfect. Didn't bother looking at a rainy day and was bored....tried the left side....WOW...drop the radiator....what's the deal???

I really didn't try too hard...wasn't that bored....

Ride Safe

To change the plugs you need to drop the radiator. If you use the supplied spark plug tool, changing the plugs is a 20 minute job. Yes change the plugs every 8k miles, it makes a huge difference. Most people upgrade to the Iridium plugs too.

Mr. Wolf,

I didn't mean to snub you by not responding to your info about changing plugs. I just did it last night and all went fine. Tips to anyone attempting this; remove the bottom radiator bolt first; then the one on the left (clutch side) and slide the rad toward you, it's on a "peg" or stud; only one bolt on top. Neat set up.

It's easier to remove ALL plug wires (they're numbered), gives you more room to work.

I did this with 12,000 miles on it and the plugs I took out looked good; golden brown. And yes, it did make a differnce in performance. Seemed smoother. Maybe it's in my head but...

Thanks for the info..

Ride Safe.
