Quick Look 2023 Yamaha YZ250F Top End Rebuild, Piston, Timing Chain And Valve Spring Replacement

[@stevenstocki3122]

Thank you for doing this. Just ordered all the same parts you listed and plan on doing this over Christmas break. Got 82 hours on my 2024 YZ450... Im 220lbs and ride mostly in the sand with the throttle constantly pinned .... Im greatly overdue ! Thanks again .

Glad I could help

Good video, doesnt look like any wear on anything important. Wonder if it would have lasted another 50 hours

[@DeRail479]

Verry true, only thing I noticed was starting a little hard so valve adjustment may have cured even though it was minimal.

[@mbvjg4217]

it would last a couple hundred more hours easily with proper maintenance. you dont wanna go that long tho but thats not my point. my friend has a 15 yz250f that lasted 550 hours before it finally blew which is just insane, also depends on your riding style

[@JaredRectenbaugh]

Good video! I want to try my hand at doing mine. I built the 5.9 Cummins engine in my 2nd gen.

[@DeRail479]

You should have no problem just measure your valve shims properly and all else is easy

[@reineherrera8897]

It actually looks great in there. You probably could’ve gone another 20 hours on that piston without a problem. What oil were you using?

[@DeRail479]

Hi, I agree on the condition and I use Blud Lubricants 10w50 every 3 hrs 👌

[@clintkeaveny8700]

How much did all those parts cost in total? Looking at doing my rebuild hopefully also around 50 hours sometime this summer

[@DeRail479]

Yamaha parts I wanna say was $400 and then I bought shim kit and valve spring compressor tool for $150 Thanks

[@SurfJdog]

How much did a rebuild cost for the yz? Curious of price difference in parts between ktm vs yamaha.

[@DeRail479]

I want to say $400 in parts and another $200 in tooling

What was the engine of your 2022 FC 350 like with the power vortex from bottom to mid range? I have a FC450 Husqvarna. But I'm about to turn 48 years old and that thing tires me quickly. and it pushes outwards in the curves due to the inertia of the engine. It is good to have a good bottom line but that wastes energy. I want a 2022 FC 350 but my only fear is that it doesn't have enough bottom-end power and can take me out of the corners since I weigh around 215 pounds. You had the fc350 22 that's why I ask for your help and your opinion. I tried a FC350 23 engine. It had enough bottom power for Mi. but I didn't like the chassis. Best regards and thank you for your help, how will the bottom line power of the 22 be compared to the 23 FC350. Here in Mexico we only have tracks with intermediate to hard terrain. They are short, low-speed tracks with tight curves. Could you use third gear more in corners with the vortex?

[@DeRail479]

Hello sir I had a 21 and 23 both had vortex and the 21 is what your comparing to was a great upgrade I had 2 maps and the max power map had lots of bottom and reduced engine breaking a lot I also ran it with one tooth up on the rear sprocket. It was money well spent

[@MOTOSYMOTOCICLTETAS]

@@DeRail479 thank you

[@MOTOSYMOTOCICLTETAS]

Did you sell the 2 husqvarnas 350?

[@DeRail479]

Yes I did sell them
