I made a post regarding the specific type of spark plug since the part # shows many different pictures and I thought this would help some people out there to know which is which. I bought my bike a couple months ago with 11500 miles on it, now it has 12500 and the plugs were never changed. Here are some pictures of them     as you can see, they are not in great shape and one of the electrodes are a little bent. If anyone does a search on how to change these out you will see many people taking about how much of a PITA they are. I think you should keep that in mind, because just like someone telling you about a movie that sucks, you go into it thinking its going to be bad, so your expectations are that low, you might actually enjoy it. Same with the changing of the plugs. I don't want to ruin it for anyone but all the horror stories I read about replacing the plugs, was not even close to what I experienced. Starting with removing the coils and how you need to use rope or a bungie cord.. lol nothing more than my hands and a couple fingers pulled them out. One youtube video talked about using a special tool and grinding down the ball on the socked end, not needed. All you need is a deep socked 14mm and one 3" extension and a simple socket swivel  I was able to torque all but 1 (#4) with my torque wrench.. Anyway hope this helps some in the future. I haven't put it back together yet but I hope it runs somewhat smoother as those plugs looked somewhat worn/fouled |

Thanks for posting this. I have done spark plug changes in the past on other bikes but the YouTube video got me doubtful on how difficult this would be. I am going to give this a shot tomorrow.

Thanks for posting this. I have done spark plug changes in the past on other bikes but the YouTube video got me doubtful on how difficult this would be. I am going to give this a shot tomorrow. It's not that hard. The hard part is dealing with the tank fairing thingys. I think there's a method out there that keeps them together. Go with that one. Also, buy some type of narrow but sturdy rubber hosing. To pull the stick coils out easier, wrap the hosing around the head of the stick coil and try to move them back and forth (side to side motion) while attempting to pull them out. This tip was golden for me in pulling those stubborn ass stick coils out. |

Hey, somebody please post the 'best' video here to know which is the most appropriate method of dealing with sparkplug changes. Or better yet, please make a better one  . Thx. Oh, and those plugs look really beat up. Wonder what kind of life they had. It'd be even more concerning if it was just a mild street life. Wonder why motorcycles don't use the better ones, like iridium, etc. |

those aren't really better plugs the Iridium's just last longer.
This was 12k miles, supposed to be changed @ 8k so that's probably why. Want to see if it helps a little with the surging my bike has, or help a little maybe.
I promise no video is needed, pull the coils out with your fingers while twisting back and forth, actually exactly as the manual says.
It comes out I promise and this is with 12k miles never changed

I didn't use any hoses to yank out the coils. I just tried yanking them out with my fingers while turning them, it was a little difficult, but came out eventually. The hardest part of the whole thing was getting the rubber hoses under the tank back in place  Thanks for the recommendation! Thanks for posting this.

I suppose its like anything its all down to circumstances. I've read people just pulling off their CAT but I had mallet mine.
Same with my plugs, my coils wouldn't come off by hand so used large gripping pliers. Also found a thin walled 14mm magnetic socket worked wonders.
It's not a difficult task, it's just made hard by the lack of room to work your tools in.

On my Honda 919 for the #3 plug: I had to drop the socket into the hole, then put the ratchet extension into the hole, get it seated in the socket, then position the socket on the plug, then use a vice grip to grab the extension and turn it with the vice grip.
Took a minute to figure out due to the lack of space to get the socket/extension in the hole at the same time and couldn’t fit the ratchet in the limited space.
But worked in the end.

Not looking forward to the spark plug change job. Ha ha. Just one question: What are you guys doing for the tightening? Apparently you can't fit a torque wrench in there, so the old-school way of 3/4-turn after seated, or what exactly? Thx.

So just like you I watched the nightmare video and was VERY discouraged. I had a fz-1 before this bike and it was tricky, but not as tricky as this guy made it seem. I read your post, used the tools you suggested and can confirm its fairly non-traumatic. Took me 2 hours start to finish. My coils would turn but not pop free. I used a long piece of 14ga electrical wire and made a loop. Starting with hardest ones first worked through all 4. Its just a bunch of little jobs combining to make one big job. So find a buddy, take your time and be patient, if you hit a snag step back and think it through. That being said I have 12,000 miles on my plugs. I ordered them at just under 8,000 but because of BO and NGK not filling orders it took me 4,000 miles to get them. I attached a picture of what seemed to be my worst one. Thanks again for the insight and help. It is much appreciated.  |
