I’ve been running their Level 1 clutch and light weight flywheel on an FM1 240tq engine for two years and it is so nice and drivable. I’m working on a built block now and their Level 2 will be going on it for sure. Seriously, don’t hesitate-it’s completely worth it.
Thanks! We love our clutch, glad you like it too!
That thumbnail is legendary
Its like you make these videos just for miata owners ;)
In all honesty the knowledge you provide is useful for any vehicle. Im entirely self taught and i still feel like an apprentice mechanic but i find everything you talk about insightful.
Another reason to replace the clutch assembly is if the throw out bearing starts to growl upon pressing in the clutch. My NB started earlier this summer and I bought a kit. Once my mechanic had changed out the parts I got a look at the OEM disk and I was shocked to see that after 145k miles the disk looked like brand new. I did go with the 10 pound flywheel but the 6 puck disk on my stock setup. My choice as I might chose to upgrade the motor later. Though a miner adjustment for me to street drive it I am happy with my choice.
Thank you guys for your wonderful and well explained videos you take the time to make.
Though I'm not a MX-5 owner, your highlighting not starting an engine w/the clutch pedal depressed is a valid one -especially when an engine has not been stated for quite some time.. Also, when stopped at a traffic light or similar 'hold-ups,' engage the handbrake and place the gear shift into N and remove foot from clutch pedal. This helps in avoiding premature ware on the gearbox internals.
Oh whoa, didn't know stage 1 could handle the modest FM turbo. Just got the stage 1 too :)
Not to pedantic, but you really don't want to use carb cleaner for a clutch/brake job. Carb cleaner has some lubricants in it for the carb throttle shafts. Brake cleaner has no lubricants and dries without a residue.
Didn't know that!!! Great to know!!
My NB I just jumped the two plugs with a wire, easy and cheap to by pass clutch. The clip is fine if you won't want to mess with making a short wire to jump the plug.
Love these videos!!!
Thank you!!
After break in period, I had problems disengaging the clutch. For months we could not find was wrong, and then, we finally found the problem. My clutch pedal had cracked at the sidewall weld spot. Flyin' Miata was patient and very helpful trying to help us diagnose the problem. If you install the Happy meal on a Miata NC and you have disengagement problems, please check that your system is properly bled, and that the clutch pedal assembly is not cracked. Yes I had a cracked clutch pedal, and it gave us a huge headache. They say the NC is really reliable, but that clutch pedal assembly is the work of the devil. Get some braces and reinforce it, before it leaves you stranded, or it creates a headache when you swap your clutch and flywheel. Just do it, and get rid of a possible headache.
Reinforcing the clutch pedal assembly and replacing the coolant overflow tank for an aluminum one, are two things every one should do any NC Miata.
Glad to hear you found it! We've seen the pedals crack on NA/NB Miatas as well, but usually it takes several hundred thousand miles.
Any problems or quicker wear with clutch kicks?
I could not find that clutch clip to disable the starter switch for the NC Miata. Do you guys don't sell it for the NC? Or is the NC not prone to have this premature wear when you start it? thanks in advance.
I got the FM Happy Meal waiting to be installed on my car 😎
Good choice!
Is the clutch switch only in US cars? My 94 EU car starts without pressing the clutch pedal but it might have been already modded by one of the prior owners.
Hi there, what I'm interested to know more about for the NA is whether the light flywheel can cause or increase the infamous deceleration buzz/grind that many NAs annoyingly develop apparently in the gearbox. I'm yet to see anyone finger a definitive cause, let alone a fix, for the buzz ... I'd definitely love to know because my NA has that noise. Any advice on known cause and known fix would be welcome, but also what affect would the lighter flywheel have?
Usually a lighter flywheel will exaggerate the noise. Just take it as character :)
Jeremy, your remark about the clutch switch, the starter and premature wear on the crank thrust bearing is interesting. I assume that when the engine has been at rest, oil has drained away from the thrust bearing. Starting the engine while the gearbox is in neutral and the clutch is engaged, takes pressure off the thrust bearing until the oil pump has time to lubricate this bearing. Is this correct?
The bearings are never really in metal-to-metal contact, there's a layer of pressurized oil in between. The intent of the clutch switch is indeed to minimize the load on the single, small thrust bearing until there is oil pressure to create that layer. We've been recommending it for decades.
Pressing on the clutch puts pressure on the thrust bearings. So disabling the clutch switch and starting the engine without the clutch in will wear those bearing less.
Is the clutch override switch really necessary for a completely stock 1.6, with an oem exedy replacement clutch?
It's a good idea because it takes a lot of load off the thrust bearing. Not as much as with a heavy clutch, but it's still a dry bearing when you start the car.
How did you guys make those air ducts where the fog lights are on the NC?
We used to sell them. I believe they were made by AWR.
What causes the pressure plate fingers to become uneven?
My stage 1 kit makes a lot of noise, replaced the throw out bearing, still there. The fingers are not even, causing the bearing to slide against only one finger and squeak, when the clutch is engaged.
Drop our support team a message with more details, they should be able to help you out. Email support@flyinmiata.com. Thanks!
The shop that installed my clutch lost the clutch switch, I have an NB2, should I try to source one or just leave it as is?
You can run without it, but it's to help reduce wear on the clutch on starts. It's up to you, and we do sell them separately if you want one.

I have a 91 1.6 Miata that I just installed a cromoly steel 11lb flywheel (Exedy) for the 1.8 along with a 949 Racing Sport clutch. The clutch works great and it took me a day or two to get used to taking off with the lighter flywheel. I like everything about it better than stock, except it makes a slight buzzing sound (sort of like a loose heat shield) when decelerating at about 3000-3500rpm. It only does it in gear and seems to do it more in the lower gears, though I do hear it in 4th too. Anyway, is this "normal" for lightweight flywheels? Any suggestions to minimize the noise? I did set the transmission height before tightening the front PPF bolts to Mazda spec and checked the torque on all of the bolts. I used new bolts on the flywheel and pressure plate and triple checked them to the correct torque. Red loctite on the flywheel bolts and lock washers on the pressure plate bolts. The exhaust system is a newish Racing Beat and is quiet with no rattles or buzzes. Engine doesn't make any rattles or buzzes in neutral when I rev it up. Any suggestions or is this pretty much normal with a lightweight flywheel?
Glad you like the lightweight flywheel! We've run into the noise you're describing and I'd call it gear chatter. In some cars, it's barely noticed while others are more prominent. Usually, a high mileage or tracked transmission is worse but we've had a few that didn't follow that thought. You can always try a good full synthetic to see if it knocks the noise down. Thanks for watching.
Do you guys recommend a lightweight flywheel on the ND2, I thought I read they come with a dual mass form the factory
It would make a massive difference in how the car drove
Is there a stage1/2 kit for the ND specifically the ND2 with the dual mass flywheel ?
We don't have kits for the ND available at the moment, but we've been testing various options and might have one in the future.
Does the stage 2 still work on a stock 1.8 with the side effect being more pedal effort, or should it only be mated to a higher horsepower motor?
It would work, but it's completely overkill for that horsepower level, so you're really not getting any benefits.
@@FlyinMiataVideo oh, I’m planning for more horsepower, just needed one at the moment and didn’t want to have to buy another in a few months. XD
on a very stock 1.8 NB Miata, I believe the flywheel weight is around the 17.5 lbs mark. Is a 13.5 lbs flywheel going to be noticeable? And ACT sells a Prolite 9.4 lbs flywheel. Do you think that's excessive on a stock 1.8 liter?
We definitely think the lightened flywheel is noticeable, and like the way it feels on most Miatas. If you go too light, the revs drop really fast and you can have idle issues on a street driven car. Give us a call or email and we'll be happy to go into more details and answer any questions you might have. Thanks!
I just got installed your stage 1 happy meal with the lightened flywheel. The flywheel is advertised as 8.4 lb. So is it really 8.4 lb or 10 lb? I am confused.
Anyway, i am breaking in the clutch, so I am driving it very lightly. All I can say, is that I love it.
Our NC flywheel is ~8.4 lbs., and the NA / NB unit is ~10.3 lbs. Thanks!
@@FMJeremy Yeah, that's what I thought, thanks. I knew the lightweight flywheel would be "chattery" on deceleration, but it also makes noise at other times under load. In any case, other than giving it a bit more gas in first and reverse gear, it is amazing in all other gears. That willing feel it gives you, and the quick gear changes are just what I wanted.
Is there any disadvantage to the lightweight flywheel for the NA? I live in a place that often has really bad bumper-to-bumper traffic
We think our flywheels are a good mix of performance and drivability, but if you go too light, your revs will drop very fast and you can cause idle issues on a street car. Feel free to reach out to our customer support team directly if you have any specific questions. Thanks!
What are the negatives with going with a lightweight flywheel? Noise?
As stated in the video, a lightweight flywheel can effect idle, especially on a car with an aftermarket ECU, and will require a little more gas when accelerating from a stop. We like the faster revs and easier rev-matching, so it's a trade off we are happy with.
Ok Eric, I’ll add a view just because you got silly for the thumbnail. Topher 94FMII aka “Major Chode”
@flyin' Miata
I'm a bit confused, this widget (ua-cam.com/video/9ELdaS1Xrxo/v-deo.html) allows you to start the car in neutral (w/o clutch) to preserve the thrust bearing ... but the number of instances where you use the clutch are far higher during gear changes on a typical drive ... saving the ONE clutch actuation at startup is peanuts right?
Anything I'm missing something obvious here ?
There’s no oil pressure on startup.
@@FlyinMiataVideo 😂🤣😂🤣 thx for that, kinda obvious looking back on it
@@DominicLeung87 Never hurts to ask!
Who starts there MX5 in anything other than Neutral?? I know you guys in the states dont drive manuals for the most part... but in the UK we grew up with Manuals... you only place / park the car in gear on hills or after a track session (essentially when you cant use / rely on the handbrake)
Not all North Americans grew up without manuals :) It's been a law in the US for decades that there needs to be a starter interlock on the clutch pedal, so it's not uncommon for drivers to leave the car in gear, push the pedal down and hit the starter.
Mazda put a heavy flywheel with a reason, didn't they? If the weight of the flywheel is smaller, shouldn't the crank pulley on the front of the engine be lighter too? I feel like they have certain weights for smoothness purposes and to protect main bearings/connecting rod bearings. Basically, the balance from front to back of the engine changes, isn't it? Isn't that going to have an effect on the engine?
The crank pulley is not there for rotating mass, it's there to dampen vibrations in the crankshaft that can damage the oil pump. The factory flywheel weight was likely chosen with more of an emphasis on stall prevention and idle quality than aftermarket ones, although if you stay within a reasonable range the car is still very easy to drive.
@@FlyinMiataVideo that is great news then, as I ordered a 5 kg (aprox 10 lbs) flywheel and I thought I was going to break something
I'd like to buy one but your out of stock until October. :(
Sorry about that, we should be getting more asap! We might get them sooner than November, but no guarantees. Unless you need it immediately, your best bet is to click the "notify when available" link in the listing to make sure you get an email as soon as we get more stock!
Please do not start using these ridiculous soy boy face thumbnails. Please.
You'd be surprised how many compliments and comments we get on silly thumbnails.
I had to Google “soy boy.”
Is this stage 1 clutch kit good to use for my 90's miata manual 🤔
You'll need a 1.8 flywheel as well, it won't fit your 1990 flywheel. But it works really well.
