So helpful. Thank you for posting this. I recently purchased a 2006 FZ6 and this was my last bit of maintenance that was confusing me. I'm typically a cruiser guy, so I've never had to remove anything to get to spark plugs before. Much appreciated
Just did this, didn't need to take any radiators or fans off, just kept everything on. Used the supplied spark plug removal tool and the 14mm wrench, that was it. Got it done in less than 25 minutes doing it my first time :D
Hey dude, I’m just about to do this. Did you just reach the wrench through the gap between the radiator and the head?
When I did them on my yzf600r I removed the bolts holding the radiator on but didn't remove any hoses or fans and that was enough to get access, gonna be doing this on my fz6 today or in the next couple days
Having the same misfire on my '04 FZ6. Putting new iridium plugs now. Thanks for the video!
Happy to help! 👍
Great you’re doing all the maintenance yourself. Just bought a similar Fazer and it is of great value to me. Greetings from Denmark 🇩🇰
Just hit about 25,000km on my fz6, this video is gonna come in handy in a week or two when I do the 25k service!
Fun stuff! 👍
so helpful! this went very smoothly. it would Not have gone smoothly without your guidance!
Anyone know if it's possible to swap them with just having to remove the side fairing and not the radiator. Aware would be tighter but could it be done?
In the video linked below, I replaced the spark plugs without removing the radiator.

Just bought a used FZ6, just over 16k Miles, so perfect time to do both the coolant flush and spark plugs at the same time!
would you make a video showing how to install an alarm on the fz6? 🙏🏼🙏🏼🙏🏼
I used your oil and filter change video yesterday and it means I'm doing my own maintenance, thank you for these videos.
Question tho, how do you measure the gap and change the gap on the plugs please? Thank you
You'll need a spark plug gapping tool, or feeler gauges. The electrode ground strap can be bent down or up slightly to adjust the gap to your specification.
Yo Calvin so I know this video is super old but I have been working on a project FZ6 for a few weeks now and I'm just trying to confirm the ignition coil are setup properly... I know that my leads are connected to the right plugs but I'm not sure if the red wire, the orange wire, the grey/black wire and the second red wires that connect to the tabs from the side are in the right order. Can you please confirm (in detail) the placement of these wires as they are to connected to the ignition coils? 🙏 🙏 🙏
Just got a 09 fz6 with the exact problem you talked about. I'm changing the plugs tomorrow with iridiums. 👍
Hello. A question. The facer is better with abs or without it?
So i have an 09, it turns over and tries to catch but doesn’t catch. Think it’s the plugs?
This can be done without removing the radiator if you use the stock spark plug tool in your tool kit and use an open ended wrench to turn the spark plug wrench. It is a bit tedious but can be done if you have small hands/arms lol
Yup. Did it that way. Not too difficult.
Please clarify that it’s antifreeze coming out of the hose, not water, and that it needs to be handled carefully to ensure it’s not ingested by animals of which is deadly!
Yes coolant/antifreeze is toxic. Never leave chemicals out for animals to consume.
Another easier way to remove the plugs from the holes in the valve cover is a small piece of rubber hose that's tight on the plug. That way you dont need to fiddle with the plug cap to remove the loose plugs. Works great in the automotive world so it should work just fine with a motorcycle.
Hello, good video, I use a piece of rubber hose the same size as the spark plug, to remove, and replace them.
To get the bubbles out of radiator, use a burping funnel.
Great video man, My Fz6 had the same probs.... thanks man she's like brand new did the air filter as well. 👍🏽
Happy to hear this! Enjoy the ride 👍
@@Calvinm Thanks man, be safe bro!
Also I use a magnetic pick up telescopic tool to get the plug out
Hello can you show how we can remove the muffler from fz6? Thank you
Thank you so much Calvin..I learned a lot thing from you..
That’s great! 👍
How can you know a plug isn't working well? By the sound the engine is making?
nice video! have you tried unplugging the fan switch? i have tried doing that numerous times but no luck. I couldn't locate where the switch is?
I haven’t seen a plug for the fan but I imagine it’s hidden somewhere.
Hello Calvin u mind telling me Wich is the best spark plug that u recommend for this bike(brand and size or number's dunno) just bought a blue one and want to give it some maintenance
The stock plug is NGK CR9EK. Some people run the CR9EIX which is an iridium plug. Best of luck! Enjoy the bike!
Use a magnet spark plug socket and swivel joint on your extension it makes the removal much easier
Hey So I know you tried a bunch of stuff to fix the misfire. What did it end up being?
It ended up being a bad ignition coil.
Hi there friend. I have noticed that the old spark plugs have the double contacts you had on. I had to replace mine as it was due for a change. My model is a Yamaha FZ6 FAZER 2004. The bike shop gave me single contact spark plugs as they said to me it is according to the book in the service manual (have to check that out) Can this give problems in the long run? Obviously the water/ coolant have to be drained to get to the spark plugs the way you stripped from the front. I done it twice from the top - I know mine was way more complicated. I had to re-serviced the gap on the spark plugs. Sounds bit better now. i am just bit worried about wrong spark plugs. If I have to change spark plugs again I would do all four and with the stripping method you used to change spark plugs. Keep well and enjoy your day - drive safe
Hey, I'm not sure if running a single ground strap plug would negatively affect the engine. I know the plug in the service manual I have recommends a NGK CR9EK which has dual ground straps. Maybe the shop who sold you the spark plugs works on FZ6's a lot and knows something about these bikes that we don't. If you know the model of plug you installed you could do some research to compare the heat range and material composition of the plug to the CR9EK plug. Best of luck!
@@Calvinm )
Hey bro is it normal when your running 170kph it vibrate to much on the upper front part of the bike got fz6n 2008 tnx bro
170kph is pretty quick. At those speeds it’s often a wheel balance issue that causes a vibration. Many people say that around 200kph the FZ6 feels a little shaky/squirrely
Can you access from the top? Seems more convenient than draining the coolant
It can be done without draining the coolant if you don’t mind working in very tight spaces. I did a video on spark plug replacement without draining the cooling system when I upgraded to iridium plugs. It’s a big hassle to go through the top because you would need to remove many items including the air box and ignition coils.
Weird that the plugs started to die just after 10kkm. I have replaced my NGK cr9e's with exactly the same new ones about 20kkm ago and I still do not have any issues. And even a small oil leak due to valve guides worn out on one of the cylinders does not make the issue worse at all. Weird indeed that you face such issue so early on.
I think he has another issue. Bad plugs make it harder to start when the voltage is low (because it can't jump the gap) and the alternator is not working yet. Should be fine at low to mid RPM when you have 14.4 volts to work with. High RPM is also where bad plugs will rear their ugly head because the coil voltage drops (from not being able to recover fast enough at our crazy high redline). Iridium plugs are not that much more. I just got a set of 4 for this bike for 20.00 on ebay. There is no reason to be doing this every 6000 miles, especially if you don't scream the engine constantly. I have 50K miles on my original plugs, no issues. . . (I know that is pushing it which is why I just got some iridium plugs, but it is true about my stock plugs and it does not stumble right now). If I were the guy posting I would connect a volt meter and go for a ride. You may have a regulator going out or you could have too many accessories going. Don't you have heated grips and also the dual always on headlight mod? That's a little more than what this charging system was designed for. I would disconnect one of those (or switch to LED lighting) and see if all of a sudden you stop having spark plug issues ever again. Also check out your kill switch! There is a known issue where the contacts go bad because the spring was designed too weak. All of us will have this issue at some point. It makes the bike stumble and cut out. It is tied to vibration and the condition of your contacts so it can happen anywhere in the rev range but it will usually be consistent. Also because it is the kill switch, it will not throw a code. Sound familiar?
@@smoke05s i sometimes got this hesitation but only if the engine is at the brink of the temperature where the fan starts to turn on and only if I open the throttle too much too quickly. But it does not happen regularly, only once in a while and on very hot days. Haven't had this issue on cold days as far as I remember. But it looks more as if the engine tries to rev but gets a delay for a second or two.
@@smoke05s small update on the "hesitation" part - probably it happened due to the fact that I went way over the service interval with my spark plags (should've replaced them after 20 ths km and they sat ther for around 35 ths. They also had visible damage from the voltage jumping the insulator and misfires. After replacing them with iridium ones the engine seems to run much smoother, though it does not seem to drastically affect fuel economy and engine temperatures. But the hesitation is completely gone for now.
I have the fz1n it's the same as your bike but I use the spark plug spanner that came with the bikes tool kit so much easier
My yamha fz1 is bogging down in first gear when i let out the clutch guy i bought it from says he changed them last session but he also said that about the tires and i found out later there tire code date said 2016 so i think he might of lied about the plugs to..but do you think that coils could cause that problem as well? Or do they just work or dont work.
From your description I think the guy lied and you need plugs. Your symptoms sounds just like mine when I had bad plugs. I haven’t had a coil fail but I think when they fail they consistently misfire, not just in first. Best of luck, if you do the plugs and your problem is fixed at least you’ll know when you need to do plugs next 😅
@@Calvinm yup your right i already ordered the nee plugs anyways i hope i dont get the hole job done and then find out it was coils tho lol. But thanks anyways
Haha ya I hope plugs is the fix too for you sake. Good luck! 👍
Thanks again for great video
You're welcome!
Also, did you have to add new coolant, or was what you emptied into bucket enough to refill with? Thanks
I always spill a little so it’s good to have some fresh coolant on hand. In theory you could replace the coolant that you drain and be back in action though.
What's the length of your socket extension, I have a 5 inch and it's too long
It’s a 3” extension I was using. Try using the spark plug tool that comes in the factory tool kit under the seat, it works very well! 👍
@@Calvinmthe last owner took it out, I managed to get it sorted thanks
Fo you think this would be the same ona 2001 fz1?
It would be very similar, not sure if the FZ1 uses the same plug through.
This helped me so much!
Great!
How similar is this change to a change on a 2010 FZ1?
Hi, What luggage mount are you using? I am trying to find a rear mount. Thanks!
Check out my video on the Shad luggage system:

Those don't look exactly like the one I have because the turn signal bracket is in a different spot but that should work to mount the side cases! Best of luck.
you can do this without draining the radiator.. just unbolt the rad and unbolt the clip what is holding the pipe what leads toi the water pump on the right hand side of the bike.. let the radiator hang down just enough to get your tools in from the front end.. also you should use a hinged spark plug tool so the tool can bend halfway.. that way you only have to put half the length of the tool in then straighjten the bend and then the tool drops down onmto the plug.. simple
It could be done that way. I guess different people have different approaches.
@@Calvinm Nice video, but I was going to say the same as Channel 13, it's simply a lot less faff to do this without having to drain the coolant and remove the radiator.
You should have a hinged spark plug tool in the standard Yamaha tool kit under the seat that is designed to get into the sockets easily.
A few notes for anyone planning to change their plugs:
1) Make sure the area around the sockets is clean and, once you've taken out the coil, use a spray of canned air to blow any crud out of the socket hole before you remove the plug to make sure that nothing drops inside the cylinder.
2) Work on *one* plug at a time. Take it out, check it, replace it, put the coil back on as this stops any confusion about which goes where if the markers on the leads are missing (any any embarassment when the engine doesn't run properly because you've mixed up the leads!!) Whilst the plug is out of the socket, use a bit of rag or tissue to stop anything dropping into the hole.
3) When putting the plugs back in, you should only ever tighten them by hand until you are sure that the threads aren't crossed.
4) Putting a little smear of red rubber grease or a small spray of wd-40 inside the cap after you've re-inserted the plug and coil makes it easier to get a good seal on the cap when you push it back in place.
A couple of other things: After changing the plugs, it's a good time to balance the throttle bodies to get it running smoothly.
BTW I don't know what the temperatures are where you live, but it looked like you were topping up the coolant with plain (distilled?) water, rather than anti-freeze. Yamaha generally say this isn't a good idea as it dilutes the anti-freeze.
Finally, you didn't seem to check the coolant expansion tank to make sure the level was between the low and high marks.
Still, it's a good introductory guide to a job that's satisfying to do yourself, rather than paying a mechanic to do it for you :-)
Hey bro is there anyway you could tell me the firing order from left to right while sitting on the bike??? I'm working on a 2009 and I did a cam mod with the three degree advance, but the bike was worked on prior to me getting it and the timing order was mixed up, by looking at the way you had the wires hanging in the video it look like 1.4.2.3, can you confirm that or not thank you
Hey, so if you're sitting on the bike the labels on the spark plugs leads would go 1,2,3,4 from left to right. As in, on the clutch lever side would be 1, and on the throttle grip side would be 4. The firing order is the order that each cylinder gets spark as the engine is spinning which is different from the physical layout of the wires. The firing order on the bike is 1-2-4-3 but this is just describing the order in which each cylinder makes power. Does that clear things up? If your bike was disassembled to all it's components it's possible someone did not reattach the spark plug leads on the the two ignition coils to the right outputs on the coil which would make it more confusing to sort out. Let me know if you need a diagram from the manual on the correct wiring from coil to plug.
@@Calvinm I could use a picture of the diagram my bike was completely taken apart and I think I have the wires running from the coils mixed up as they were not labeled
You definitely do NOT need the special tool OR to remove the radiator to do this.
5/8th/16mm thin wall UJ socket with a short extension.
That's all.
I have a Snap On one that while was costly - it has saved me a fortune in time and been able go do all of the awkward bikes such as the ZX12R
Wow dude awesome video .. thanks for help - done pretty easli
Hello i got 1 problem please can u help me. When i shift gear from 3 to 2nd or another one sometime my motorcycle is going off (motorcycle yamaha fz6 s2 naked). If i change the sparks it will be solved?
Hey, It's possible that you have a spark plug problem but it sounds like it's more likely something else. Check your side stand switch is working properly. Maybe when you bump the gearbox to shift the bike it vibrates the side stand switch causing the bike to think the side stand is down and therefore turning off the bike. Make sure the wiring connection to the side stand is clean and firmly attached. Also check your neutral safety switch which is at the bike of the engine/transmission for a clean firm connection. The neutral safety switch is a small single wire connection if I remember correctly. Also check the electrical grounding point on top of the transmission is not loose. It sounds like you have an intermittent electrical problem, but I could be wrong. Easier to check these things before spending money on spark plugs. Hope this helps!
It is possible to change the bougies without something to remove.
Hi Buddy, may I know how to change temperature display from F to C ? Thz so much
Hold down either the Select, or Reset button (I forget which) while bike is running.
@@ShadowRockers I tried but can't, it's change KMHh to MPH only
1. Turn on the main switch with the “RESET” and “SELECT” buttons held down.
“Co” appears in the left of the display area for the distance and time.
2. Press the “SELECT” button. The display changes to “dIAG “.
3. Press both the “RESET” and “SELECT” buttons at the same time.
“d01: xx” appears in the display area. (A certain number is displayed in “xx”.)
4. Pressing the “RESET” button 2 times displays “d62: xx”.
The “xx” in “d62: xx” indicates which thermometric scale to display, Celsius or
Fahrenheit.
“00” = No display
“01” = Celsius (°C)
“02” = Fahrenheit (°F)
To change the display, operate the engine switch “OFF” → “ON”. The thermometric
indication changes in order of “00”, “01”, “02”, and back to “00” and so on.
@@ShadowRockers much obliged
@@ShadowRockers still can't, would you please take a video ? Thz
What I will say is this swivel on swivel on swivel to get the socket and number three and two without having an issue at least that's the assumption I have going into my attempt with my 09 fz6r
with the caps off its worth to check them for conductivity, because even if they give spark, meaning the engine is running fine, they could be fried inside and instead of 5kohm there is a carbon gap. A multimeter should read ~10kohm between two caps secondary coil.
Yes that would be a good thing to check! Particularly if the plugs measure and look okay when you take them out.
Thank you 😊
if you want to send your email I can give you photos and measurements to adapt a handlebar damper that was very good...Congratulations for the videos won a subscriber from Brazil
If you could send me a message on instagram @freeheadgasket that would be great. I am interested in adding a steering damper. Thank you.
I have 33 k miles on my 2013 fz6r with original plugs so am not sure why 10k kms (7k miles) brought about considerable wear on yours???
I'm not sure either but I think when I installed the plugs they were already at the outer limit for gap and the mileage did them in. Unless you're running iridium or platinum plugs you'll probably need some soon with that mileage but lucky you!
So I was able to find a PDF of the full serviceand in it is exactly what I found what you said 1 2 3 4 is the actual firing order but for some reason many people on the internet have it as 1 2 4 3 switch on a 2009 fz6r is definitely
Incorrect so thank you for your time good luck
I see, glad you got it sorted out!
Just pull the tank and the air cleaner box, easy peasy!
Tank, air filter, battery box, ignition coils, its a long way in that way too
❤❤❤
7:07 dude that was tap water. You will corrode the system at the first 100km 😂😂
Nah man, just using a big cup to mix the antifreeze, distilled water.
👏👏👏👏
U should use NGK iridium plugs in the bike....they last around 80 000kms and they perform slighly better as well....then u dont have to keep changing plugs every 10 000kms
@Scott B which model NGK iridium plugs do you recommend?
Aye before y’all take your radiator off and make a big mess Yamaha gives you a tool you put a 14mm ratchet on it. It sucks balls but can be done with it. I had the same misfire as you and it went away with brand new plugs!!!
You're right, Yamaha does make tool for this. I used it in video I made much later after this one. You don't need to remove the radiator but it is rather painful without removing the radiator. Glad you got your misfire resolved!
