Dude this vid is awesome! Man, you've honed in on some of the most useful/valuable bits of knowledge to be shared w/ the MX community, be it service work or aftermarket parts selection. I can't ride this weekend because North Alabama is getting swamped out w/ rain, so this vid is my track time for the weekend haha
@@kdcustoms1272 the bills pipe , and Pro Circuit Ti silencer are a great combo . really enjoying my 2022 125 , i run T2 fuel , Apex head , a wiseco piston, and JD jetting kit , really livened it up a LOT. so much so i was able to change sprockets from 13/49 , to 14/48 , and lost no low end , but gained HUGE up top.
Dustin liked the Scalvini because he rides in the upper rpms. That's one thing I noticed off the get go. He really likes to rev to the moon. I've heard fitment issues with Scalvini from at least 85-90% of people who buy them. Personally, Pro Curcuit for me. Great video...
@@thomasphilyaw8593 for sure, I agree. For me the chassis stays more under control when I'm in the sweet spot. I will say I'm so surprised how well he rides because he only has about 2 years of track time. When I first met him a year ago is was all over the place. Now I gotta give it my all to just stay behind him. He's learning so fast
Dustin is a good rider I just getting into this I got alot of practice to do I haven't been to track yet just a big field on someone land but I'm getting better each day
LOVED ❤THAT YOU TESTED THE STANDARD PIPE ,SOMETIMES THESE ARE BEST POWER SPREAD & AFTERMARKET PIPE BUILDERS COPY VERY CLOSELY TO THIER SPECIFICATIONS. IMPRESSIVE TESTING TOO . AWESOME TO TEST ON DIFFERENT DIRT TEXTURES
Scalvani had a pipe with problems. Mxa called them out like 15 years ago. Scalvani fixed it in response. Mxa rated it their best after the fix. Mine is awesome. I have a pro circuiut silencer long on my yz 250, a shorty on my 125. An rv pipe on the 125 and scalvini on the 250. Do some wider searches on the various pipes. That looks like an old girl to me.
Please try the Cisco’s spring from Cisco’s racing in Australia. It runs about $60 shipped to your door and I’ll change out the real stiff YZ power valve spring and you’ll be blown away at how it changes the nature of the bike power everywhere. no real hit just right. When you crack the throttle it’s truly impressive.
WELL DONE A GREAT VIDEO ON REAL WORLD TESTING, ITS THE ONLY WAY TO TEST . BACK TO BACK IS THE ONLY WAY TO REALY FEEL THE DIFFERENT STRENGTHS & WEAKNESSES . LOVE ❤️ TO SEE MORE MAKES JSV DOMA HGS WITH THE ONES YOU RODE WITH ON A TRACK WITH HILLS . KUDOS TO YALL 💃💃💃
Oh man I would have loved to have a HGS and others here. We only had what we had and the FMF was a surprise lol. i dont think there are any tracks in Florida with hills though lol.
Good to see another track ride video. You had the track to yourself; I guess everybody know don't disturb UP ALL NIGHT WHEN he testing at the track As far a vp race gas go which one do you recommend for 2 strokes ?
LoL. Moto Bros opened a new track just up the way from lazy springs and everybody was over there for he grand opening. I will give it a few weeks for the crowd at moto bros to calm down some. VP C-12 is about the best for the smokers
You mentioned the heads are different on the 2003-2010 yz250s, can you still buy those heads OEM? I have a 2018 im building into a dessert race bike but I’m 250lbs trying to get all the power I can within a reasonable price. I’ll probably notice more performance gains if I loose weight lol thanks for the video.
Hello. Yes the 5UP head is still available from yamaha although its not cheap. I have had some luck finding good used ones on ebay from time to time. Just make sure it doesnt have any dings or damage. But here is a link to the new OEM ones from yamaha www.partzilla.com/product/yamaha/5UP-11111-00-00?ref=28ab6a726698db582367d81735166c1bceb42c26
@@UpAllNight91 If i remember correctly the 250f swingarm is a little longer than stock and the 450f is a little longer than the 250f...its only like 1/4 inch. I'm really not to sure though, It's been a few years.
Clutch pull is way better but it doesn’t fully disengage running stock plates. I put a toque drive clutch after burning up the stock one in about 15 hours. So far it’s been working well.
Clutch pull is surely easier. I like the new body work. But it is kinda a trade off. Seat feels a little taller and firmer. It does kinda make it feel like the front end steers better. But the older one feels softer in the seat area and kinda easier on the butt during long rides.
Hi my friend...i have the yz 250 2024 and i just put on the procircuit platinum pipe and pro circuit factory sound...in midrange i have so much wheel spin and at low or high rpm is worst than the stock...and when i let the rpms goes low i have so much engine braking like a 4 stroke...is that normal?
That sounds weird to have engine braking from a pipe. I haven't experienced that myself. Maybe try putting the stock pipe back on and get a good back to back? The PC pipe does have less bottom than the OEM pipe but will have more mid and top end. However to get the top end pull out of the PC pipe it does require a little bit of jetting. Mainly the main jet likes to be a little leaner than the OEM pipe does. PC recommends 175 main for the PC pipe but thats at sea level at 70 degrees. I currently run a 172 main in the summer and 175 in the colder winter days.
Maybe the factory sound silencer make the engine braking?I will try the exhsaust back to back....reed v force 4 will help me on lower rpm and leaner jetting to make the bike faster on low rpms?
@@Lostre450F If your looking for more bottom end power with reeds I would suggest the V Force 4X without the spacer. I actually did a review on this if your interested, here is a link... ruclips.net/video/WleTE9GVRMk/видео.html
I have never see it happen myself. Too much oil in the gear box usually just causes over flow out of the vent tube. And too much oil in the fuel will usually just smoke like crazy and foul plugs.
@@JackMacdonald-ih3ht Hello. I cover this better in my 2 stroke oil ratio video but I dont see a huge change in jetting with changing the premix ratio a reasonable amount (like going from 40:1 to 25:1), at least not a whole jet size change. Maybe in the old days when oils like golden spectrum was thick as honey but these days I just dont see much of a jetting change when I change up the premix ratio.
Good informative pipe video on revving the gonads off it, but where was the use of any torque ?. Not impressed with your's or Dustin's cornering technique 😮 !!! Free wheeling into sand corners is about as wrong as you can get🙈
The reason all mx riders use shorty silencers is because they give more top end not bottom end , that’s why all enduro riders use longer silencers because they give more bottom end
You will hear people say longer silencers are better for top end and vs versa. Especially back in the day. Even magazines would claim this (Which I never subscribed to that theory personally) . Enduro riders are usually required to have a spark arrestor so thats why their silencers usually look long. On the hare scramble races Ive done that require a long spark arrestor silencer it seemed to kill top end but also didnt help the bottom end any. Didnt like using them at all.

Oh man rain! Glad to hear the video was enjoyable and somewhat a pacifier for the weekend. Hopefully next weekend is perfect and makes up for it!
Interesting information about the silencer lengths.
Bill's FTW . . . . . best pipe i have ever ran . nicest material of the raw pipe options too .
Would have loved to have one to try today. Hopefully one will come around soon.
Everyone I've ever heard that tried that pipe loved it.
@@kdcustoms1272 Would be nice to try one

You wouldn’t lose any low end because you lowered your overall gear ratio from 3.50 to 3.69.
Another fantastic vid packed with info and expierence. Thanks.
Thank you!

Thanks! Yeah Dustin surely keeps it up on the top. He might actually be buying a Scalvini now.
@UpAllNight91 He might get faster running a little lower in the power band. Trying to keep it in the sweet spot up top can be a little harder

@@UpAllNight91 HGS is also a top end pipe
We’ve been running hgs and really like it
Right on. Been looking forward to trying one of them as soon as one comes around.
the GYTR pipe is actually a HGS
@@UpAllNight91 it's similar to the Scalvini: the HGS it's kinda soft in the bottom end and screams at the top
LOVED ❤THAT YOU TESTED THE STANDARD PIPE ,SOMETIMES THESE ARE BEST POWER SPREAD & AFTERMARKET PIPE BUILDERS COPY VERY CLOSELY TO THIER SPECIFICATIONS. IMPRESSIVE TESTING TOO . AWESOME TO TEST ON DIFFERENT DIRT TEXTURES

Low end pipes all day
I just have a gnarly gold series for my 01 cr250. Hills and trails
Right on! Them gnarly pipes are also a lot harder to dent.
More weight👎😂
I’m hoping to get a 2 stroke dirt bike in 2024. Deciding between KTM or Yamaha. I own a CRF450RL and love it although I do miss riding a 2 stroke
Right on! 2 strokes are fun thats for sure
@user-fz8fy4zl1c Congrats on the new 23 YZ.
I'd get the YZ just because they have been the same for 20 years... Easy to find parts and cheaper.. but that's just my 2 cents.
Although electric start would be sick😂
@@kdcustoms1272 Surely parts can always be found
Awsome review!! 👏👏

You ever considered a 09+ 4 stroke swingarm swap? I got a 09 250f arm but never got around to it because my lower rod bearing went out...
No I havent. My understanding is its a long swingarm which will extend the wheel base some. I would like to try someone elses though

@@kdcustoms1272 Right on. I have a buddy that did the swingarm conversion but I havent tested it out yet.
Wonder how that hydraulic clutch feels on the newer bike, also how do like the new styling on the 22+ yz's?

GYTR FMF FATTY IS THE BEST BY FAR
Is the GYTR a different profile than the normal FMF?
@@UpAllNight91 According to fmf it's the same thing.
@@rztrzt ahh ok. Well I can say from this review the FMF was one thrusty pipe. I really liked it.
FMF is what I have I love it so much power
Tin pipe gets hot quickly and 2 strokes with hot pipe loose power
yes, the stock pipe holds the power better than most pipes, I believe
If I ran to much oil in my yz 125 mix could it cause to much heat and ruin bearings i heard someone say this
I have never see it happen myself. Too much oil in the gear box usually just causes over flow out of the vent tube. And too much oil in the fuel will usually just smoke like crazy and foul plugs.
@@UpAllNight91 oh ok so to much premix in your gas isint gonna run hotter and kill bearings
@@JackMacdonald-ih3ht I dont think so. at least not within reason. I would avoid going richer than 20:1 but yeah, should be good.
@@UpAllNight91 oh ok and does more oil in gas cause leaner air/fuel ratio because the gas is thicker and harder to suck in?
