Absolute win!! So happy for your success dude, and thanks for showing us your diagnostic journey. Funny thing is, just last week my fz6 started throwing intermittent error 33 codes. (Ignition coil malfunction) its thanks to your videos that I know I can't fully rely on resistance testing the coils.
At least you got an error code! My bike wouldn’t pop a single light on to tell me what’s up. Glad the videos were helpful to your diagnostics 👍
Had the same misfire problem had checked the coils and caps like you but
Still misfire.
Fitted new coils now fine
Thank you
It’s strange how this has happened to so many people!
Thank you so much for going through the trouble of sorting the misfire and at the same time share it with us. This is by far the best videos of fz6 that I have come across. Will try swapping the coils and keep fingers crossed. FIY, I am having exactly the same issue as you.
Thanks a ton for these videos.
Ya it seems like many people are having a misfire issue with their FZ6. Good luck with the repair! 👍
Hi Cal. Been watching your vids for a while....awesome! So glad you fixed the misfire problem. You must be relieved and falling in love with this great bike even more now. I just clicked over 65,000km on my 2008 FZ6S S2 and still love her as much as the day I wheeled her our of the showroom! Glad you are showing us all how to keep the old girl running smoothly. Cheers from Australia.
Yes I was so happy to have the FZ6 back in good health. Thanks for the kind comment! 👍 enjoy the ride and stay safe!
Congrats!
And thank you for the info, I'm sure this will be helpful to many in the future :)
Thanks! I sure hope they’re helpful!
Thank you for the video. My 06 sounds exactly like yours with the random misfire at idle. I’ve suspected electrical since it is worse in the heat, just haven’t spent more time than ordering some plugs for it. This will give me a good path to follow.
My problem ended up being bad ignition coils… took a lot of tinkering but after swapping out the coils for another used set the problem went away for good. I hope you solve your problem easily!
Love your vids man!
Thank you!
The misfire on my 2004 fz6 turned out to be a bad throttle position sensor. Yamaha had an outstanding recall for that, and the dealer replaced it free of charge!
Apparently this applies to 2004-06 fz6 models only so wouldn't have been the issue for you, but maybe this knowledge will lead somebody to call the dealer and ask the question even if their bike is now 20 years old 😊
Awesome video! Just bought a 05 fz6 and it had the same exact problem. Coils were the solution for me too
Nice nice. Good to know!
did you replace all the coils or just one? and did you buy new chinese or used coils?
@@Dannyyzeee I replaced both coils. They were used OEM coils.
I am having same problem with my 2004 FZ6 , did all the coil test too. Well 2004 is 18 years old, the coils some do break down. So guess I will try coil replacement. Thanks for sharing your videos. Very helpful 👍
Was it your coils?
Awesome bro I promise to follow you as long as I own my fz6 😅
Great 👍
You're a true asset to the FZ6 community. Random question: Do you play D&D?
Thanks, and no I don't play D&D
WOW, congratulations & well done. So I know where to go to from here.
Thanks!
called it on the coils! very frustrating issue that happened exactly the same for me. Seems to be a fz6 specific thing
Nicely done! Ya I wonder what it is about the FZ6 coils that fails like this.
I just checked my valves and after putting everything together the bike has a misfire. Pretty upset about it, thankfully its winter and Ive got months to figure it out. Triple checked all coil connections and cable order. All cyls have spark at wires, I'll go ahead and replace the plugs and see if that does it. Its got to be a damn coil or plug, because I looked at it wrong. Istg nothing ever goes smoothly, Im trying to be as thorough as possible doing work on the bike and its clowning on me. Doing the fork seals was a shit show too, the steel tube was stuck like crazy in the bottom tube, though I was going to break something. The stuck spacer was literally submerged in oil but still didnt budge without lethal gorilla warfare. The other fork went smoothly as intended by satan, first the stuck one to have me wondering if Im doing it wrong, then the easy one.
Update: It was a damn plug! Measured the coils too for extra reassurance.
So glad you got it sorted! 👍 Plugs can be so finicky! Fork seals are a big job too
Calvin Hi.
I had the same problem with my bike (same bike) in fact... i did EXACTLY THE SAME AS YOU, i bought a entire throttle body assembly as it was a very good price, and mine was very dirty anyway, so.. i have two now jajajaja but it didn't solve the misfiring problem.
In the end i realize the problem was the ignition coils all along but there is a problem with FZ. It's a waster spark system and i found various disavantages with this dual cylinder system.
* First. if the problem is the coild it could be de spark plug connector leaking energy
* Could be thhe cable leaking energy
* Could be the coul itself leaking as they can breake
So in the end... you have a 3 possible part fail per coil, making it a 6 possible failure points....
So i just forgot about the absolutely obsolete system and install 4 Yamaha R1 2015 individuals coils making 2 series.
Now my bikke runs like a dream... and if in the future i have one coil failing, at least it would be easier to change and diagnose, change the coils like this is very easy, you dont even need to diassembly the bike, you can do it in the little space that ithere is left, and you can diagnose one by one... and whats more, you can even found them very cheap even new with chinese coils that works very good.
That is a little tip for you (because i iamagine you did use theh FZ6 coils again).
That’s wild that you had the exact same problem and also tried to change the throttle body assembly! I like the idea of changing to a coil on plug design, it is a lot more modern. Is there a website or article you followed to do the conversion? I would have to read more about the wiring for the R1 coils to understand what wiring is needed to trigger them. Thanks for sharing your experience! 👍
@@Calvinm HI Calvin, not really there is no website i just realized i could do this myself if i understand how the system works and is very easy.
In fact i will explain now so anyone else could tried.
The basic principle is, that the FZ6 behaves like a Twin Engine at ignition level by a system that Yamaha calls. Goup Type Fuel Injection, that is made of two cylinder bodies and is commonly called at automotive industry at the ignition system like a Waste Spark Ignition System.
Basically at ignition level is... when the bike one to ignite Cylinder 1, it send the spark to 1 and 4, and when the bike one to ignite cylinder 2, it sends it to 2 and 3, and when it ignites 3, it ignites 2 and 3 again and same with cylinder 4. So Cylinder 1 and 4 is a group and cylinder 2 and 3 are the other group, they are ignited together all the time, so its called waste, because when the bike ignites one cylinder, their pair it's not at the explosion stroke, so it's spark is wasted.. Yamaha do this because is simpler and cost less (The basic principle at the FZ6 a value R6)
So what i did is... the idea is to foul the FZ6 ignition system into think that it has the FZ6 ignition coil, and the ECU sense this via the coil impedance. So i need it to find a coil that it has at least half of the FZ6 impedance, that according to FZ6 service manual is 1.53~2.07 ohms (it varies according to temperature) and so when i put 2 together it would have the same or close impedance of the FZ6 and voila. Yamaha R1 2015 to 2019 according to their Service manuals use a ignition coil of 0.85~1.15 ohms, that is about the half impedance of the FZ6, most exactly the model that i used is the Mitsubishi F6T558 of a 2015 R1.
I bought a used R6 ignition coil wiring loom, rewired so the medium could be at series and the 1 and 4 cylinder could be the other series, put some end plugs so it would mate with the FZ6 electrical loom and it start immediately without hesitation, without any issue, and i have been using this system for almost a year or so.
I read all R1 and R6 Models service manuals and i found that from year to year the ignition coils impedance have change, the models of the coils have changed too. BUUTT i heard to that t hey are all interchangeable, there are some Denso, there are some Mitsubishi, but it would work with all fo them, looks like the ECU is not so picky regarding impedance, so in the end, maybe what i did to select the most close one in impedance, is not necessary.
Here you go, that is the way you can have the multiple ignition coil system on the FZ6, and it works for the XJ6 too and the OLD R1 (199x) that it has the same coils found on the FZ6 and they aver very hard to find and they are expensive.
I was thinking about this mod about two years ago, when my hesitation at low rpm started, is annoying and i always suspected to be a high energy related problem and i prefer this solution than using the stock ignition coils because, as i mention before on the stock one... you coil could fail, you high energy cable (coil cable) could fail, or the boot could fail, so... is very hard to diagnose and maybe you change your coils and the problem wasn't the coils, but the boot, and like wise... is very annoying.
With the Direct on Sparkplug system, you don't have all those elements, there is only the coil and that is it and you can diagnose it one by one.
BTW. I recommend you if you do this and even with the stock coil boots, always use dielectric grease at the coil boot tips, and the coil boot body until the top, so it will help to isolate the current and will impermeabilize the system, so when you wash your bike, it will prevent ignition failure because of spark leakage because of the water.
Finally, kudos for your channel, i love everything about it, i do all my bike work my self too, and made some very interesting mods too, i love to see a great community around this wonderful bike, the best bike Yamaha ever produced for me... and sorry for my English, i am from Colombia and Spanish is my primary language.
@@cyberkiller83 Wow Leon! You are one smart guy! Thank you for the detailed explanation on how you made the coil on plug system work. I agree that there is many places for the FZ6 ignition system to fail and that coil on plug is far superior.
Once again, thank you. From your explanation I could put the system together no problem. Your english is great!
@@Calvinm Thanks Calvin, and continue this great work, this kind of videos are the ones that makes CZcams great, these are far superior and educational than the traditional viral stuff that you see everyday.
Keep it up and know that you have one avid listener here jeje.
@@cyberkiller83hello brother, i experienced the same thing on my fz6n. I need to look for the right coil but can't find it because I'm in Cambodia, and here the big motorbike mechanics don't understand how to handle my motorbike. Can you help me?🙏
Glad to hear you were able to fix it! What was the part number of the coils you used?
Really Happy you found out what happened. Mine is having a problem lately on start-up. It takes a second attempt to start. Any ideas?
Thanks me too! Hmmm that sounds odd, maybe the fuel pressure regulator isn’t holding fuel pressure while the bike sits for a while. Does the bike start first time after it was running very recently? Or always a two crank start?
I'm experiencing the same thing now, can anyone help me find the coil. because I'm in Cambodia and buying from eBay can't be sent to Cambodia😢
Try the website megazip.net or partsfish.com. I know megazip has international warehouses, hopefully they can ship to you 👍
COILS FOR THE WIN!!!
Let us know what happens to your mileage.
🎉🎉 mileage has been about the same since filming this 👍
I've replaced mine with used ignition coil from 2013 fz6r it falls within the original spec.
If this thing break again, im gonna push for COP style mod
Sometimes parts may pass the test, but in reality its actually faulty.
Awesome!👍👍👍
Thank you! Cheers!
Hey Calvin can you please tell me before change the coils did you measure the volt of your battery with all the lights on? It was 14 volt or you loss power ~11volt ? And when you measure the coils it was everything OK?
The voltage off the battery was fine with lights on or idling. The FZ6 doesn’t produce much charging voltage at idle so that can be problematic if you spend a lot of time idling. If it wasn’t idling with lights on I’d get like 12.4 bolts ish. Hope you resolve your issue.
@Calvinm thanks a lot for your answer and the videos. Please tell me your opinion I have a broblem with my fz6 s1, when I start for first time everything work greatfull but when I stop and I start again then a lot of times it work with 2 cylinders for about a minute and after this it works perfect . I have change ignition coil spark cups spark tps I have clean all the wires ,injections gas tank kill switch and the problem still here . Do you have any ideas ?
where the link to the video you menction that you have remove the ITB on other video?
czcams.com/video/jhlvvXSrNB8/video.html
@@Calvinm thank you .... so i just take off my itb off from the engine, and after reinstall it back i can feel and hear like a vacumm leak on it. and there no leak before i take it off. any sugesstion what i might do wrong here? ☹️
What do you consider a "good price" for that part? Just out of curiosity if I ever have to go that route with mine.
I got this ITB rack for $100. I usually compare to Ebay listings to get a reference on pricing when buying things locally.
ih calvin , misfire fix change Ignition Coil ?
Yes!
I've got the FZ1 I've just chased the same set of problems. About to pull the injectors. Did you ever try swapping the coils around? I did and didn't see the problem move. I also see a spark when running the bad cylinder's coil with a spare plug outside the bike.
I didn't try swapping around the coils. I suspect I would have seen a spark on the plug even though the misfire was happening. It would be hard to see the misfire happening since it happens so fast. Best of luck!
@@Calvinm thanks! Good point if it was occasional it might not be obvious. Luckily for me my miss is constant i.e. completely cold cylinder. I'm working through it and documenting on the 998 forum if you are interested. Just pulled the injectors and the one for the troublesome cylinder has clearly got dirt in it. But so do all the others 😱
hi . I have a question about fz6 .. I also have a symptom below 2000 rpm when the engine is hot, when I accelerate the motorcycle shakes under me until 2000 rpm .. after that it rotates linearly .... how could I do a Test? with the engine cold to wet the exhaust.
You can try wetting the exhaust but the best thing to do would be to measure the resistance of the coils. Although many people now have noticed that the coils can measure fine but still be the problem at low rpm. Good luck!
@@Calvinm I will do a synchronize throttle bodies.. let's hope we get lucky
Hi Cal, just read your reply for my comment. My mechanic suggested I replace my steering head bearings at 70,000km which is 4,500km away. Is this necessary or should I wait until I feel much slack or notchiness? Also my Michelin Pilot 5 front tyre needs replacing soon, although the back still has much service life. They are noisy on my FZ6S S2 although not on my son's MT09. Can I put a Pilot 6 on the front and they won't affect the handling or be noisy? Again, greetings from Australia.
I wouldn’t replace head bearings until necessary. That kind of stuff rarely goes back unless it’s exposed to the elements constantly. Not really sure on the tire situation. I think you can mismatch but it’s best to have a matching pair.
If it works dont touch it! Only do regular maintainance and find a new mechanic, hes obviouisly after the bag or an idiot. Steering bearings are quite the job, I just did mine because they were rusted out because prev owner blsated them with water Im guessing.
A good brand tire shouldnt be loud, you might have a defect tire or a different problem. You can mix match tires unless ur pushing the limits but this isnt the bike for that anyway. Good brand street tires all have very similar constriction and level of grip.
you are a fucki.....genious man, i see all your videos before i get my fz6 s2, im going to make a statue of you !!! thanxs a lot!!!! and sorry for my bad english, im from Rosario, Argentina but i live in Barcelona.
Haha thank you man! I hope you enjoy the FZ6. Ride safe!
hey man, did the new coils improve your fuel consumption?
No, they didn’t. Strangely, I felt the new itb rack caused worse fuel consumption even with the coils fixed so I switched back to the original itb rack with the now fixed coils. I haven’t put multiple tanks of gas through the bike yet so I’ll report back but so far the fuel economy seems a little better with the original itb rack.
Hi. Maybe do you know why some S1 models have whistle sound?
Not sure what noise you’re referring too.
@@Calvinm im about sound like in this video. Some of S1 have it, some not. Maybe have any ideas? czcams.com/video/KCq7vQ2RNGY/video.html
That's pretty standard intake noise on the s1. Nothing to worry about
perhaps your multimeter is goign bad :D
Haha I wish! It turned out to be a bad ignition coil…
👍👍👍👍✌️✌️✌️
🤓👍
Good 💩.👍
I wanna to explain a some trap for electric newbies. The ignition coil is a high voltage transformer. Most often they short-circuit between windings. If the short circuit is between, for example, 3 and 5% of the wire's length, you will not measure anything wrong with an ohmmeter. But for a transformer it is like a short circuit, like driving with the handbrake on. A bit of theory: bobparker.net.au/lopt_tester/k7205.pdf Greetings from Poland.
