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!
