2010 zx14 spark plug change - 2006 kawasaki ZX-14

bosch or NGK mag wires are best.
plugs any you want , if car short miles car, every year go cheap plugs , if hard to reach go best plugs.
I like NGK the best, but there are other good brands.

Sounds like you didn't get the spark plug wires put back in the correct order. Check them to be sure they are on the correct spark plugs.

There isnt really a mention on how often you should change your spark plugs some manufacturers say certain plugs are good for upto a certain mileage
Check with your spark plug manufacturers recommendation on spark plug changing intervals

You need first remove the plastic top cover by pulling back. Then, remove the spark plugs using a 16 mm plug wrench.

let the ford dealer do this job. its very complex. It really shouldn't have to be done as most engines have lifetime spark plugs.

you need to remove the ignition coils and you goin to see the spark plugs

Down into the center of the valve cover, where the 4 wires are leading into.

well if you had a 02 zx12r I could give you a copy of mine and I love mine it's fully modified with full Muzzy's exhaust and everything. but since you don't, I got you a pdf download. go to http://www.pdf-manual.com/vehicle/motorbike/kawasaki/manual-ninja-zx-14-2010-18376.html the download button is on the right side of the screen second panel down i believe. hope having the whole manual helps, lol.

Just changed my plugs on my zx 14.. THe manual recommends .32 to .36...So I gapped it to .34.....
