- Dialing back the 2023 Yamaha YZ450F to 350F using the Yamaha Power Tuner. The app says fuel and ignition settings can be adjusted +-10 steps. To see how much response and power feel could be dialed back I created a map with -10 on both Fuel and Ignition. Wow! Really slows down the engine RPM build and dials back the power. A nice option and kind of like having two bikes in one with the push of a button. Fire breathing 450F moto bike or much slower revving easier to ride 350F.
May wanna try richer fuel . Straight from the app in the engine tab it says .
decrease overall power - increase fuel over all rpms decrease ignition timing over all rpms.
Yes lots of options to change the power character. This was just a test of trying to see how much it can be dialed back - feels like a big rag stuffed in the airbox!
Love this video!!! My riding area the 450 is a rare bike, tight tech trails, everyone rides 250-300 2 strokes or 250 and some 350 4 strokes. With the wide range of adjustment available on this yZ450 with the smart phone app, the 450 is once again a viable option!! Just load that map on map switch position 2, and you literally have 2 bikes in one!! smooth 350 and fire breathing 450 with the push of a button. Long races, bet most guys would eventually end up in the 350 map as they get tired! Thank you!!!
Yes such a useful option to easily tune the engine character with a phone - Yamaha leads the way in with tuning apps.
Wait for the '24 YZ 450FX. It'll have the new frame and engine (like the '23 MX bike).
Once you have played around with your “350 map” it would be really interesting to see a woods loop comparison between a YZ250FX, your KTM 350 and the YZ450 in 350 and 450 modes.
If you could just crack on and get that done that’d be great 😂
Thanks for all the videos by the way.
Michael - glad you like the channel and I like the way you think...more back to back woods loop videos! I've got no access to a Yamaha YZ250FX as of now but do have 21 KR350, 22 MC350, 23 350SXF, and my 23 YZ450 with what ever map I decide to use (though the stock map is my favorite so far).
Wouldn’t you max out the fuel and take away all timing and it would be at its slowest possible mapping? Now I want one of these. I’ve always thought 450’s were too fast but if you can tame it that well… I want one then.
Lots of ways to dial back the 23 YZ450F - this was just retarding the ignition all the way and limited the fuel as much as possible. I this video I left the fuel stock and retarded the ignition in steps from -10 down to -7 (I think!)...at the beginning of the video I show the numbers. The bike ran well and was noticeably smoother.... ua-cam.com/video/MsJrtPo70xg/v-deo.html
The more I watch about this Bike, the more excited I am getting about the 24 450fx.
Yes imagine an updated '24 YZ450FX with the new chassis, wide ratio 5-speed, off road tuned KYB suspension and the fun to ride character of this new engine all with a kickstand!👍
I don’t like the idea of a wide ratio transmission they’re putting on the X. I went with the 23 YZ feeling I could dial it down with mapping and send the suspension to Enzo to get that good for mountain riding and track. But hard to argue it’s a prebuilt all in one bike
@@TheHuggybear516 I bet Enzo can dial in the KYB suspension for off road!
@@mxengineer1 couldn’t you just put a bigger sprocket on it to long out the gears
@@adamrochester1 Yes gives you that top speed but makes 1st very tall for tight stuff and also opens up the gaps between gears. I Rekluse autoclutch can help with the slow stuff. The wide ratio FX 5-speed should be very good...maybe later this summer Yamaha will make the 24 YZ4550FX available?
Thank you for the video, I really appreciate it!
I’m picking up a 2024 YZ 450F tomorrow. I haven’t ridden off-road in a while, everyone I spoke with told me to get either a 250 or 350.
Then I met a YZ450 rider who’s also in his 50s, and a bigger guy like me. His advice was to get the YZ450 and make it into whatever kind of bike you want with the tuning app.
I wasn’t super clear on that until this video. Thanks again!
Congratulations on your new 24 YZ450F! Such a cool bike! Here is a later video with a more refined dialed back "350" map.... ua-cam.com/video/-Bsk-3UoEHo/v-deo.html
Ok so I have the opportunity out to buy a 2024 450fx for the same price as I will pay OTD for a 25 yz250fx. Having never ridden a 4 stroke I’m not sure what to do here. I am comfortable on a 300 2 stroke and I am concerned the 250f will leave me sad in the hills of southern Ohio. Oh and I can buy a 2024 TC250 OTD for 8300. I will ride combo of moto and single track/harsecramble type stuff in southern Ohio. What’s your opinion?
So many choices! 24 YZ450FX is a BEAST!!! Even dialed back that engine is still super responsive and strong. The chassis is firm and reactive - a little busy at speed but that quickness is good on the trails. YZ450FX will laugh at the hills. Here is a better YZ450F dialed back video... ua-cam.com/video/MsJrtPo70xg/v-deo.html
25 YZ250FX might be the sleeper choice. The new chassis feels really good on the 250F with improved ergos and more agility. If you are used to riding a 300 smoker any 250F will have just enough power most of the time and perhaps lack enough power some of the time - just have to keep it pinned and revving. The YZ250F engine runs has the best partial throttle low to mid roll on torque feel of the 250F's.
I rode a 24 TC250 and liked the lower suspension, total lack of vibration, and power was stronger than expected after coming on my 23 TX300. Smooth, fast, and fun... ua-cam.com/video/_VTj89Cm_MU/v-deo.html
For me an Austrian 300 TBI smoker (KTM 300XC/Husky TX300/Gas Gas EX300) is hard to beat as a Do-it-All 2-stroke. For 24 model year the new WP spring cartridge fork works great. All of those bikes have rebates now (TX300 is $1500). If you are a picky rider I would spend the extra money on a 25 model of the Austrian bike with the updated frame. The improved bump compliance and tire contact patch feel is noticeable.
Let me know what you buy!
Congrats, you have a detuned 450.
Is it still faster than the 250f when dialled back?
Oh yes - still very responsive but more controllable. This is a better "350F" map I came up with (details are in the beginning of the video).. ua-cam.com/video/-Bsk-3UoEHo/v-deo.html
I don't get this video I paid for a 450 ima get the power of a 450 for my moneys worth
That is one way to look at it! The other is if I can smooth out the power and response it's like getting two bikes (a 350 and a 450) in one! The 23/24 YZ450F has a VERY responsive engine that some riders like the dial back a bit - I wanted to see how far back a YZ450F can be dialed.
I thought i was gonna go with a 24 300xcw but your vids on this have me thinking. LOL
I really like my '23 KTM 300XC and it tends to make most 4-strokes feel a bit cumbersome with a lot of engine braking feel but I don't get that sense riding the '23 YZ450F back to back with the '23 KTM 300XC
Thank you Thank you! I am only 140 lbs and the bike doesn't know I am on it and I was hesitant to what you did so can't wait to go ride.
It is still a 450F moto bike but the engine response can be noticeably tamed down with the Yamaha Power Tuner
You actually want to give it a little extra fuel or keep it at zero
Yes - good recommendation. This was just a "lets find out how much it can be turned back" with full negative 10. I will be trying out some more maps soon
@@mxengineer1 I’ve had my 22 for over a year now and if I’m in the woods or tight racing, I have the fuel around zero and the ignition near all the way down to take away the bite.
@@kristofers3562 Yes I want to try simply retarding the ignition and leaving fuel alone - that should smooth the response for woods riding.
You read my mind , I’m planning to buy the 2018 yz450f and wanted to detune it …. 450s have a lot of power Hahha great channel
These tuning apps can be very good at smoothing out and dialing back the power on a 450F and it kind of makes it feel like you have (2) bikes in one based on what EFI map you choose! KTM's now offers the Connectivity Unit Offroad that has throttle response, engine braking, and traction control tuning...reducing engine braking can make a 450F "feel" lighter in motion... ua-cam.com/video/HxeEdoKL6co/v-deo.html
Can you screen shot the map. Id like to try it
I have a screen shot on the cover page for this video - it is basically -10 everywhere except 40/60/80% throttle at 10000 RPM where I dialed back from -10/8/5/3 on Fuel. You can also see the settings on my phone at the start of the video
More fuel and less timing is the way to go mate if you want to detune it. and a lot safer on the motor
Yes that video was just checking the limits Yamaha provides. I don't like the rich feel and prefer to dial back with just ignition timing as I did hear...still a beast! ua-cam.com/video/MsJrtPo70xg/v-deo.html
2nd time watching this 🍿😂
Thanks for watching! I think this dialed back map ran better.... ua-cam.com/video/MsJrtPo70xg/v-deo.html
An u please send me the picture of your map so I can try to make my bike a 350 thanks
I think what you have done is way better than buying a 350, because if you ever want a little more all you gotta do is make a couple clicks. If you bought a 350 and wated more your talking engine work, race gas or big bore kit. What you have done is 10x cheaper and gets the same effect.👍
Very cool that Yamaha offer this feature on their YZ450F!
Love it! Just done it to mine!!!
Cool! This was a better "350" dialed back map on my YZ450F... ua-cam.com/video/MsJrtPo70xg/v-deo.html
Awesome video. A friend of mine has a 2024 yz450f that he'd like to tame down quite a bit at times. We have the power tuner app but it will pnly let us adjust traction control and nothing else. Is there something were missing?
When you make a new map the Yamaha Tuner automatically shows the simple slide bar adjuster for FI/IG, TC, and LC tabs. In the FI/IG tab just above the #7 there is a little white circle with (3) tiny slide bar icons....tap that little white circle and it will open up the detailed Fuel Injection and Ignition RPM vs Throttle 4x4 grids and you can start adjusting away. Make changes and go ride the bike and see what you feel (if anything). Have fun!
I wonder what maxing out the fuel leanness does for the engine life though.
That is a good question. I assume Yamaha has completed durability testing on the complete range of ignition and fueling changes allowed in the GYTR tuning app. VORTEX or GET ECU's tuned by private individuals can probably get into ignition and fuel settings that are outside of what Yamaha recommends. Here is a more effective dialed back "350" style map I made for my 23 YZ450F... ua-cam.com/video/MsJrtPo70xg/v-deo.html
@@mxengineer1 Oh for sure it says in the app that it's not possible to damage the engine as long as you use high octane fuel but running lean will make the engine run hotter and reduce its lifespan.
@@6Twisted Yes that is one reason I tend to retard the ignition if I want a smoother throttle response
The thing is, the reason 350s are great is their light feel, not soft power.
Yes 350's are such a great combination of Power/Weight/Handling in a 4-stroke dirt bike. Here is a better "dialed back" 23 YZ450F video where the smoother power helps make the bike easier to ride on a woods loop... ua-cam.com/video/MsJrtPo70xg/v-deo.html
I really like the 25 KTM 350XCF.... ua-cam.com/video/J3XLv4H0JUY/v-deo.html
@@mxengineer1I rode a GasGas EX350 for two years. It was incredible. Felt lighter than a YZ250fx, with most of the punch of my YZ450fx without the tendency to wear me out.
Hey I bought a wr450f but don’t have the map switch button connected to the handle bar, ive screwed it on but am unsure on where to plug it in and can’t find anything on line could you help me?
I don't have any experience with the WR450...maybe go to a local dealer and see where the map switch connects on a 24 YZ450 and compare to a WR450. The 24 WR450 is all new. The YZ450 had the bluetooth unit behind the left side number plate.
Got my bike 6 months ago rode the bike every weekend 4 months straight then got cold put it in the garage and on a power charger bike won’t start now changed spark plug just cranks getting fuel and full battery not sure what’s wrong
Mine did something similar after washing it with a garden hose (no high pressure). Would crank but not start. I pulled couplers and blew out with air hose. Clicked everything back together and it started right up. After that put di-electric grease in all the couplers. Check couplers for corrosion and good connection - even the ECU coupler.
Hey will longterm use of turner app for making the bike a 350 damage the engine of the bike? just curious I want a 350 but I would love to have the extra power also.
Yamaha states in the tutorial video on the Power Tuner the allowable settings will not damage the engine. Load the app into your phone and start learning about it. Here is a link to the tutorial... ua-cam.com/video/MuzZrXZHNgc/v-deo.html
Can I pay a thousand dollars less because it runs like a 350 😁... just kidding . love the content great job 👍
Bicycle companies often charge more for less weight and power in e-bikes! Glad you like the channel!
Does it feel like low revving and torquey 250f with that setting? High revving actual 350s feel kinda nice and just like a high revving 250f with almost 450 power, or an older version 450 to me.
The map does slow the RPM build and power but not to a 250F level - still has much more torque. I think this new '23 YZ450F engine revs so quickly and freely that it makes it very fun to ride - kind of like a 350 with a lot of power. So far I like the stock map the best though it is nice to be able to change the engine character with a phone!
I'd think a quiet slip-on would do the same for the other 450's, yes?
Yes I believe a more restrictive and quieter muffler would soften the throttle response and make it easier to ride. A G2 throttle cam would also slow the response. Easier to dial back power and response than add it!
Can you do this to a 16' with the power tunner? I mean, are those values avaliable?
Yes you can change values of ignition timing and fueling on a 2016 YZ450F but I think you need to use the previous hand held unit and not as many RPM/Throttle positions to adjust...I recall a 4x4 matrix but it has been a while since I used that hand held unit on m y 2016 YZ250F and I sold it a few years ago! Get ahold of it and try retarding the timing a lot - see how that effects the throttle response and power character
Brilliant, I just asked a friend yesterday if this was possible and you provided the answer. Could you compare the feel to a KTM 350 XC-F if you are familiar with that bike? Thanks! Great work!
I will be doing back to back rides with KTM and Gas Gas 350's soon. I have a 21 KTM 350XCF Kailub Russell Edition and used the myKTM connectivity unit to dial in back to 250F level... ua-cam.com/video/C9Yw_l4NHTo/v-deo.html
I have a 22 350 and it's a great bike I just wish I could push a button and have a track in my back yard 👍
Yes that is my buddy Dave's place - lucky to be able to ride there!
Can you send a picture of the map settings please
Check out this video where I dialed back the power character of my 23 YZ450F with changes to the ignition timing (my "YZ350F" map). This map ran well in the woods....the map details are noted at the beginning of the video. Nice that Yamaha provides the option to tune the engine character! ua-cam.com/video/-Bsk-3UoEHo/v-deo.html
How would this compare to a yz250f?
More inertia and weight feeling and a lot more power/torque than a '22 YZ250F. I will do a back to back with the '22 YZ250F and '23 YZ450 soon
is there a downside to running it so lean for an extended period of time? this is a great idea to use a larger displacement and de-tune it if it works out without lasting negative effects
That is a great question! Yamaha says in the Power Tuner information they will not let you adjust anything to the point of damaging the engine and the tuner allows +-10 points of change of fuel or ignition timing. The YZ did chuff a bit off throttle - but no stutter or hesitation on throttle. Pretty cool to have multiple bikes in one with just a change of EFI map!
@@mxengineer1 that's good to know that yamaha was smart enough not to trust us to do whatever we want with the bike but provided a range that is not detrimental to the bike to work within. no if only the aftermarket world had as much to offer for yamaha as they do for KTM turning a 450fx into an adventure bike with a larger tank might be a really fun bike to have.
Taking away fuel will actually produce more power not less, to the point of being too lean that is. For less power add fuel and be rich and safe.
I am doing the same basic thing with my KX450x and the Kawasaki calibration tool. Creating a map that smooths the bottom end and makes it easier to ride in the woods.
@@Randy_Cox Thanks for the input. The Yamaha Power Tuner app recommends taking fuel away or adding fuel to lower or smooth the power output. I tried taking fuel away in this video but as you noted going richer can soften smooth the throttle response. Fun to be able to dial in the engine character with a phone!
@@Randy_Cox what year is your bike ? how much does the tool cost to put on ?
Great review. Awesome bike , really versatile for an mx 450. Can they get any better???
I think so! Lighter weight and lower cost...gotta dream big!
Do you -10 on everything? I wanna do the same
Yes for this video I simply minimized everything so -10 on Fuel and Ignition on everything. Not the best map - just checking how much the power/response could be dialed back. I think just retarding the ignition -5 to -8 and leaving fuel stock will also slow the throttle response - easy to try different settings.
I knew this was coming ! And I just bought a 22 ktm 350… 😢 please do a comparison!!
I will get the 23 YZ450F back to back with my KR350 soon. Realize dialing back the power on the YZ450 does change the inertia or weight feel (ie it is still a 450) but does help smooth the engine response which can help make it easier to ride in some conditions. The 350's are such a great combination of Power/Weight/Handling in a 4-stroke off road bike. Enjoy your new KTM 350!
I just bought a 2024 YZ450 FX and I have a 2022 KTM 350 XCF which I love, I bought the YZ 450FX for the Nevada desert and the track , I would like to dial back the engine braking on the YZ450fx to match the KTM, does anyone know how to reduce engine braking on the YZ Tuner app? The YZ450 fx is 10 lbs heavier than the 350 but does not feel heavy.
On the map you made for this video, what Rev Limit do you have it set to? 8000?
Not sure I understand. I put -10's pretty much everywhere and turned TC on high. I left the rev limit for Launch Control at 8000rpm but I have not engaged launch control - no effect while riding.
I always think your Chanel is jwalks from you icon
Didn't notice that till you mentioned it! Jeff has a great channel
@@mxengineer1 you as well. I did comment one time thinking it was him. Probably confused you haha. Thanks for the content man
cool
So....could you dial up the 250 and get an even lighter and more flickable bike with nearly 350 performance?
Slowly the engine response does not reduce any engine inertia or weight feeling - just makes the engine smoother with slower RPM build and less power.
lol no. The 250 is essentially at max performance, all you can do is dial it back or move the power/torque around the rev range. No map is going to give you what an extra 100cc can.
Lol....I guess I already knew that answer. So,guess I'll just keep my 350s
@@jameswampler3135 The EFI map tuning allows the engine character to be changed noticeably - that can help dial a bike in for different riding conditions (like taking a 450 moto bike off road riding)...all by using a smart phone. Sometimes using the myKTM app I dial back the power on my KTM 350XCF so it is more like a 250F and easier to ride on tight trails and can result in quicker lap times.
Does it feel like a 350
This is a much better YZ450F dialed back to a "350F" video...and yes the throttle response is much smoother and power reduced - easier to ride.... ua-cam.com/video/MsJrtPo70xg/v-deo.html
Very helpful, thank you !
I did a more recent "YZ350F" map with just dialing back the ignition timing - runs better and works pretty well in the woods.... ua-cam.com/video/MsJrtPo70xg/v-deo.html
Thanks for doing this video.
Easy to change the character of the new YZ450F engine...with you phone!
I feel like the twisted development dual injector kit I put on my 2022 YZ250FX made it like a 350
I have not ridden a YZ250F with the dual injector but I can imagine it makes a lot more power. I assume you are running a specially mapped VORTEX ECU that controls the extra injector?
@@mxengineer1 Yes, mapped by twisted development. I just had the ECU updated with some new maps. We have the same taste in bikes. I have a 2023 300XC and had a 350XC-F until recently. I also purchased a 23 YZ450F a few weeks ago.
@@mikeb4708 Great minds think alike! What model year 350XCF did you own? I am curious your opinion on the 350XCF...
@@mxengineer1 I had a 2021 that I raced for 2 years in GNCC and hare scrambles. It had Xact Pro suspension and a tuned Vortex ECU. I liked the bike because it was fast enough to stay with the 450s on the start and I had a enduro tune in the ECU so it had good throttle response in the woods. I struggled with the suspension set up and ultimately I couldn’t find comfort on the bike. I started racing a 2022 YZ250F and would find that I felt much less fatigued at 5he end of a race. The dual injector kit on the Yamaha makes it rip like a 350. They only place I felt like the KTM had an advantage was it turned a little better with better front end feel. I am excited for the YZ450F as it appears to be a better turning chassis. I will still be riding the YZ250FX for hare scrambles. The 450 will be my MX bike and at the moment the 300XC is my Enduro bike.

350...400...450...depends on the map!;)
I would love a Dyno
Would be interesting to see actual numbers. Very easy to feel the slower response and lower power output from the seat with this dialed back map.
There is a Dyno test out in the google world of a 2023 with max power from the tuning app and lowest power. Don’t quote these numbers but I believe the max HP was like 57 and the lowest they got it to go was 51. I will try to find the link.
i bought my 450fx so i can use it as a snow bike in the winter, but didn't want to buy another bike for summer. this makes me worry less, i just picked the bike up yesterday. im really happy about this.
The tuner can help change the power character of the YZ450 engine ...let me know how your like your new FX!
Does this setting make the bike feel heavier in motion? Does dialing back the quick revving nature add to engine inertia feel at all?
Love the videos. Keep up the great content!
Thanks! Not going to make the 23 YZ450F feel any lighter or heavier - just slower revving and a little less power.
