Thank you this work like a charm on my 22 YZ450 FX looks like your initial torque on the rear spring is about 2 1/2 inches down. Hey guys if you're replacing your rear spring on the new Yamaha it's just three bolts and you could pull the tank right up there's plenty of slack on the fuel line and then two bolts to get the shock assembly out super simple
I am impressed with the amazing and educational videos you give us all. regarding new springs for my Yz 250 2022, I am in doubt. I weigh 70 kg naked and have been informed that the standard springs, both in front and behind are for heavier people. can you inform me about what I need. Regards from Denmark
Hello and thanks! The 2022 does have one rate stiffer springs and slightly stiffer valving than the previous YZ250 but it needed it badly. Honestly at 70 kg its probably about spot on if you plan to MX the bike. I weigh the same as you and for me I like my bikes a little on the stiffer side so I plan to go up (when I buy the new model here soon) maybe another spring rate or two (based on test rides I have done on the new model). It does start out feeling a little stiff when new but after it breaks-in it surely softens up some. How does yours feel for you? too soft or too stiff?
thank you for awesome video. I wish you could add link to the springs and description what springs for what weight to get. can you help me out. if I am 178 without gear. what spring should I get for my rear shick for my YZ250X 2017? again appreciate all your content! good stuff!
Thanks! Hello. Balance is important so if you plan to swap to a different rate shock spring you will want to also change out the fork springs to match. Now sure your level or type of riding so its hard to suggest but I can say I ran 5.3kg in the rear and 0.47kg up front for a while and it was a huge improvement over the stock springs. Firmer, stayed up in the stroke better but was still plush enough (was weighing 160 at the time). A year ago I went up to a 5.5kg on the rear and 0.48 up front. Thats surely on the firmer side yet still smooth, stays up in the stroke well and handles hard hits well. I have a suspension series where I give some recommendations and selecting springs. Its one of my earlier videos and its kinda long and winded but that can help. Here is a link to that ua-cam.com/play/PLyockiXvbg8G4nEIuCtfJg6TnmvQ6NoAC.html&si=k4Xw2JhMyP3RYPU7 Hope this helps
Looks like you lowered those forks about .5". I lowered my 2019 YZ250 2-stroke .75 on each end, and about 1" off the seat. That bike is stupid tall. Now mine is sensible. It is a matter of physics.
I made the same mistake that everybody else does when they put on their front wheel. "pumping the forks" up and down, or that "spin the wheel and hit the brake" method to get the fork legs parallel do not work. Your fork legs will not be parallel and wedge themselves in the upper tubers causing more wear and stiffer action. For my 2019 YZ250 2-stroke, (and probably your bike.), I figured out the distance between the lower fork legs, and cut a piece of 1" diameter aluminum round stock to 5.661" long, faced off on a lathe. Now tighter the axle and pinch clamp on the disk side, and leave the pinch clamps a bit loose on the other side. Put the rod in between the fork legs as low as you can, (fits through the brake disk), and tap the lower leg with a soft mallet until the rod is tight between the fork legs. Now tighten the pinch clams, and carefully remove the rod. Your legs are now parallel within + or- .001", and you may have to go to a stiffer spring because the action will be smoother as your suspension compresses.
@@northernspur6282 you can loosen the bottom pinch bolts on the right fork. Slide a small flat head in to ply it open just a hair to free it up some. Then slide the fork inward and outward and see how far it goes each way. Then place it in the middle of the two and tighten everything back down. Thats usually good
How did you like the work from Enzo? I know Donn Meada is a bit of a goof, but his older brother Ross, (owner of Enzo), has a lot of great experience with the factories, and seems like a very sharp guy.
@@UpAllNight91 Same with Race Tech, getting certain parts. I scratched the ID of my shock body, and they got me one from Kayaba for $200 some bucks. It was a "blem" though, (Blemish, a term we use sometimes for a false cut, mistake in machining.). It has a small mill cut, (anodized after) at the top of the shock bolt eye on one side. No big deal. One thing I know you don't want to do is buy old Yamaha plastic OEM. I bought 2 2014 front fenders, OEM Yamaha to replace the modern ugly thing, and you would not believe how twisted they were. Yamaha is obviously farming out their old plastic to some factory that has no quality control at all. Those fenders should have been ground up and thrown back in the injection machine hopper. Yea, I had to CNC mill new holes in the 2014 fender because of course, Yamaha has to change the bolt hole pattern a bit. That is how much I hate the modern abstract art junk plastic on my bike? :) Doug in Michigan.
@@EarthSurferUSA lol. So true on the plastic. My brother always says yamaha replacement plastic are usually blems. Your the first I've heard say that beside my brother. Twisted fenders and crap lol
@@UpAllNight91 Yes, that curved tool with a tooth at the end of the arc to catch the notches in the rings is a spanner wrench. Good guess. :) Mine doesn't fit though. Used a punch and small hammer.
@@UpAllNight91 do u know the stock spring lenght? (Yz250 f 2022) And the shock spring lenght? I wanna change to lighter springs (cuz 140 lbs) and i wanne make shure the lenght stays the same
Hello. I dont know them off hand, maybe check with racetech or factory connection. I dont have any of these springs on the shelf right now to check. But I will in about 2 weeks
Thanks so much for the content, if i am recommended to go up .01 up on front springs kg/mm but up a lot on rear can i get away with just doing rear? 2021 yz250 really surprised that i cant just run stock. Thanks!
.01 is not much on the front. Balance is very important with spring selection. But there is always a little wiggle room. Like for a 5.3 rear spring, a .46 up front is balanced, but also a .47 is also going to work good and be within a balance. So thats where personal preference comes in and do you ride more front end biased or rear. Not sure if you caught my suspension and chassis series, Spring selection and balance was covered in them videos and that might help you. BTW Thanks for watching!
Question sir. I am watching the vid again before I change my springs, and you mention you don't have to take the forks off the bike, (I think). Can I leave the forks on the bike, (on the stand, front wheel off) and drain the oil at the bottom, (the rebound adjuster), and just remove the guts from the top to replace the spring? Thanks Doug in Michigan
Ahh, I guess not, because you have to compress the fork to get the wrench under the assembly. So I remove the forks. I won't have to remove the handle bars. :)
Can you use 2022 yz250f fork springs on 2022 yz125? I am needing lighter fork springs for my weight but can only find the 4.2nm springs for 2022 yz250f
@@UpAllNight91 But on the other hand, after you drained one fork into the measuring cup, it looks like it reads 500cc or more. Is it camera angle? cup not level? Already had some oil in it?

This is by far the best KYB spring change i video on youtube.
Thanks!

Hello. Yes the 2022 YZ125 uses the same springs as the 2022 YZ250f, however the rate is different. YZ125 is 0.42kg and the YZ250f is 0.47kg
Would the process be somewhat similar on an 2003 Yamaha YZ250F
The shock, yes. But the forks will be different. That bike has cartridge forks instead of SSS forks. Thay are a little different.
Service Manuel says 550mls not 330mls of fork oil
Maybe for inner and outer chamber combined. But outer alone 550 would be way way too much
@@UpAllNight91 You are right. The sealed cartridge holds 205cc, and the range of the outer chamber is 300cc-365cc in my 2019 manual.

@@UpAllNight91 But on the other hand, after you drained one fork into the measuring cup, it looks like it reads 500cc or more. Is it camera angle? cup not level? Already had some oil in it?
