VHM Head Install on 2024 Yamaha YZ125. Better than a pipe? High Compression "SX" Insert.

- The VHM cylinder head is a really easy, quick modification that should provide great performance benefits. This is being fitted on my 2024 Yamaha YZ125 with the High Compression dome/insert to see if I can pick up a little more bottom. If I don't like it, I can just swap out the insert for any number of other options.
No doubt the claims for a much cooler running head must be true with the drastic increase in cylinder head coolant volume and huge coolant passages of stock.
This build will also see a full FMF exhaust and a drastically re-tuned carb with the JD Jetting kit. This should be one great running YZ125.
Stay tuned for the after build start up and some great ride vids coming up!

Hello sir, I'm a little lost with the nocks, there are from 10:80 to 11:80, which one to put to have the biggest bass for enduro? Thank you very much, greetings from Spain

Does the VHM head and standard insert add much extra power?
I can't say that it does. I don't have the standard insert, so unfortunately I cannot really say.
We’d just loose the gasket and use silicone pretty much the same thing
Question, why doesn’t Yamaha make it like vhm head?
They want to save money.
@@GOATbro_Australia you’d think they’d want to make the best engine possible to compete with the Austrians
Can you reuse the stock O rings in the head or need new ones ?
You can reuse if they are undamaged and in good condition. New rings are cheap though, so something to consider. I think I paid less than $10 for the set.
@@GOATbro_Australia thanks. Not about the cost but availability.
@M3FTMFW got it. I ordered a set from revzilla.com and they took about two weeks to arrive. Longer than I had expected.
Which insert do you have?
The SX insert
