Word. The moment you think you have it all figured and prove unwilling to accept another point of view is about where I lose interest in anything you’re trying to convince me of. Not interested in your products or services at that point, let alone the accolades you’re hanging your opinions on.
My ‘23 YZ450F has finally settled in though 👍 I got the chassis to quit kicking my butt after ~20 hours of riding and dicking with clickers or sag. I ended up back at a relatively base setting and it’s been dialed since. Clutch is still a little soft and the rebound may be a bit too quick still in the rear, but I’m all in on this new gen bike.
I have never made it an "we vs. them" situation, but it seems you have for some reason? In fact I've stated many times over that we need both engineers and test riders, in this thread and in others. You're making the argument that perhaps I'm wrong (the engineer), yet at the same time you seem to be making the argument that Keefer (the test rider) can't be wrong. Why is that? Why is there no burden of proof on his end?
We've tested with A LOT of riders, from weekend warriors to top professionals who are much faster than Keefer. I understand the limitations of testing quite well, and there are a lot of them! Just as there are in engineering.
Last year we had a top professional rider (one everyone here has heard of) give very different feedback for two identical sets of triple clamps. And by identical, I mean they were as identical as they possibly could be! They were made in the same manufacturing run one right after the other, from the same bar of material, anodized in the same lot, assembled by the same mechanic to the same specifications, tested on the same track back to back, etc. I could not make them any more identical if I tried. Yet the rider felt a (rather significant) difference between the two. Would you argue that I should listen to his feedback when I know he tested two identical parts and got different results? What happened there is he went into the test expecting them to be different, so he came back with different results.
Track testing can be quite valuable, but there can be some significant limitations to it too. Knowing and understanding these is critical. Keefer is a good rider and a good test rider. But he's simply off his rocker with this one. Go ahead and ask some other engineers their opinion and see what they say about it. Just because I told it like it really is doesn't make me hard to work with. I've found quite the opposite, really, and the good engineering managers appreciate it if I can back it up. If Illumina decides not to work with us because they read a post on Vital, well, that's fine with me. But that would be strange as they're already a client of ours...
I don’t know if it’s a possibility of this being the fix in your situation, but since that code pertains to the intake pressure sensor, it may be worth rerouting the CCV that goes into the airbox on the 23’s. Being the description is a circuit code and not the air temp port clogged code, it’s not likely the fix but worth a try to eliminate future issues after you inspect. On my 23 I have a 22 model CCV hose ran to the atmosphere and then capped the nipple on the airbox to prevent pressure sensor issues with the oil getting caked in there.
Yes '22 FMF muffler will fit '23 bike

It does, I had one on my 23 for a bit. I just took it off for a full Akrapovic.
After Keefer.. yes Keefer said FCP mounts were great I wanted to test what difference different engine mounts will do. Made cut out ones to test softer upper mounts still running stock at front. Coming down hill with braking bumps bike was moving side to side more with softer mounts as stock mounts bike stayed straight and felt like suspension was working better same time. Dont know how soft FCP mounts are but after this test I would save my money and run stock mounts. Will do more testing but that was feeling first week just testing mounts keeping everything else same.
Anyone found stiffer clutch spring yet? I just cant deal soft spring and short time with plates in soft sand. Yes in hardpack soft feeling is great and plates will go longer but in deep sand they wont last.
I got the rekluse torq drive pack working well. The adjustment ring does change how much bite it has. The 3 it called for was way too soft down low but with setting 2 it pulls perfectly down low. I was able to lug 3rd easily on setting 2 which is what I wanted. Setting 1 was un rideable with the plate thickness I have.
I had contact with Hinson but it will be a couple of months before one will be introduced.
Hi Scott,
Thankyou for your reply.
So after a bit of work and some help from a team here in Australia. I unplugged my ECU and found some water and grit in there. I cleaned it all out, dried it, plugged it back in and now it's all good!
I will be doing this every few rides now to make sure that it is dry and not happen again.
The bike now runs fine and fault code is gone.
does someone know when they usually introduce the next years bike?
Im not sure if I should buy a 23 now or wait for the 24..
Tape the rubber boot around the plug.
Someone said today….
That’s exactly what I found too.
Some 2024 YZ450F detail:
https://www.yamahamotorsports.com/models.php?product=177&action=product…
https://www.yamahamotorsports.com/models.php?product=178&action=product…
Only glanced, but seems like BNGs, yes?
Seems to be no changes on the 450..
Man why did they go with black rims on the 50th Anniversary Edition? Should've been silver.
Either no changes were made or they fixed some of the issues without shining a light on them. Curious to see more details from the mags about changes
Usually updated parts numbers for update parts. Maybe they are happy with engine/clutch if no updated parts.
Pit Row
fantic or yamaha?
I will look into that !
Hopefully this information on here can help some others!

Got any sand set up tips you've found with set up ?
Right now I’m running 4mm fork height with 104 sag. I’ve tried 2mm up and flush with the forks but didn’t like the way it felt. I’m still chasing a setting where I don’t feel everything in my hands. I’m using all of the suspension and it’s not that it feels bad, just too much feedback for my liking. I have FCP mounts coming and also have a 17 swingarm to try still.
How much longer is the 17 swingarm? 😀
13mm or so. But as you know on the 23 you can’t have the wheel all the way back with the current 13-50 ratio. So when I get it on I’ll measure the swingarm pivot to axle length on both and see where it ends up. I’m assuming I’ll have an extra link or two on the chain.
I have a 14/51 setup and its pretty much all the way back. 14 tooth also calms the rear too, its a win win
also, I found the stock engine hangers modified did help no doubt on the hands, no question about it. I machined out my stock ones, not the FCP. Although I plan on buying the FCP as it also comes with the front mounts too. I honestly believe in works. I tested back to back on my modified stock ones and it was quite a difference. The comfort was noticeable, took away the jarring feel in rough stuff.
How much you did cut them and what kind of track you riding? Just upper mounts or front also?
I machined basically the same shape as the FCP, just a little smaller as I didn't want to start too big and junk the mount. Yes, just the upper mounts. But it was noticeable right away with the chassis just not being so stiff and deflective feeling in the forks mainly. I ride off road only, so cal desert chop and square edge whoops kind of stuff. It would really be noticeable I believe at places like Glen Helen where it gets all shitty later in the day. Just haven't made it there yet. I'm so convinced I'm going to just buy the FCP because I also want to front one peace ti mounts too.
Mine is between 12-14mm further back with 13/50 and 17 swing arm. Noticeably more balanced and stable in the chop, less pitching from what I can tell and still turns great.
