So stoked to see a yz250 yesterday in Arlington! Talked to Jared and his mechanic Michael for bit. Super friendly, seemed more than happy to talk about their setup. Idk, just 2 down to earth dudes and honestly besides watching the racing it was pretty much the highlight of my day. The bike was just so sick, sounded amazing!! Lol the only thing Michael wouldn't talk about was the piston you put in it. Top secret insider info! They had nothing but good things to say about this engine you built. Got to admire the guys that really put it on the line like that.
From what i gathered there is a STIC in the carb, so it's there, but i might be wrong, if so HP have to correct me there. But again different engine conf package different aproach.
Hi just i just wanted to ask which 250f is best allrounder for me, i am crusing on trails, fields, hillclimbs and etc. Never going on track. Can u give me an advice what should i get
Curious about ceramic bearings. I know wheels are an easy upgrade, but wondered if you utilized them for the engine? Lighter is one benefit, but rolling resistance seems like it also could be applied.
hey man, just wondering... I got an 01 yz its got a 144 kit, Vfoce 3 reeds. Lectron. what all would all do to it if i where to send it out to you guys, Looking for somthing to keep up with the modern 125s. Thanks!
modern 250fs are ridiculously good - notably factory bikes. Im not sure a full works 250 2 stroke would be any better with a few exceptions in outdoors. but for sx I think the 250f would be better sadly

Motor looks great hope to see it in a main this year kid can rip
Why don’t we hear much more about the STIC-metering block? Don’t you use them anymore?

He is running a stic. I forgot to mention it.
Nice work!

Hard to say! I think you should consider an off-road model, such as a ktm xcf, or similar.

They add no power. Sad but true. Done incorrectly they can cause issues in reliability as well.
Ford tried ceramic bearings in their diesel turbos for a couple years. Didn’t work out very well.

@@HPRaceDevelopment Its a athena 144 kit, They are chinesse but they are doing me well so far...
Not one person recognized Jared's voice in the video? lol
not jared
Role reversal: The AMA should allow works 2 strokes in the the 250 and 450 classes. Imagine what we would see.

@@HPRaceDevelopment what about a 150 vs the 250f
@@SL4US the 150 is a tad off peak hp and waaaay off the avg power
What HP does it show on your dyno and with what pipe?
we published a video of a yz250 build, its similar to that engine
@@HPRaceDevelopment btw what timing does yz250 like when talking about top end Power? I heard 3 degrees advanced gives about 1 HP on top
@@xfdfff2620 depends on the combo.
@@HPRaceDevelopment I mean like similar porting as u and with Pro circuit or dep Pipe
@@xfdfff2620 It's unlikely it's similar porting - unless we did it...
Go rent some dyno time and buy a dyno tire, see what works best for your combo.
Awesome video, because I definitely didn't want to hear it run🙄
check his instagram out or catch him at arenacross tonight and supercross race near you!
What hp this motor has????
what dyno we measuring on
@@HPRaceDevelopment excuse me but i don't understand your answer.. i would just like to know how much power this motor produces...
@@panosgliaos5725 different dynos show different results
It’s a custom engine you’ll never know 😂
@@HPRaceDevelopment to the crank
Who’s the rider?
