VHM 2 PIECE CYLINDER HEADS
We may sound really biased about VHM products.........that's because we are !!!!
The unique two piece design allows the convenient and cost effective solution to getting the correct compression ratio as well as more efficient cooling.
The CNC machined outer cover takes an insert of your choice, there are a number of different profiles available, for various fuels and performance levels.
VHM are constantly developing new profiles and if you want to develop your own, we can supply you with blanks to machine also
We recommend you also consider the VHM setting tool. All VHM inserts come with a piston protrusion measurement that the head is machined to. Using the tool you simply set the squish by the amount the piston sticks out of the top of the cylinder. This save the hassle of using solder and is really accurate allowing a small amount of adjustment, or ensuring your bang on every time you change your sometimes not so bang on pistons. You also ensure you have constant port timing on your cylinder.
If you run different cylinder heights, VHM will, by special order make inserts to suit.
Everything VHM has made for us has been of the finest quality, accuracy and on time. They are a pleasure to work with and really good people.
VHM PISTON HEIGHT TOOL

VHM PISTON HEIGHT TOOL
Essential for measuring the correct piston projection to set the default squish for your VHM heads. We also machine std cylinder heads with piston projection values so you can use this tool to set your squish as quickly and accurately as with the VHM heads.
We use this system for all our engines now, saving time and increasing accuracy and adjustability for your squish clearances, available for RS 125/250 and most moto x ers .
Comes with simple, easy to understand instructions and made to the usual fantastic VHM standards.

Note: The Volume is calculated on the bike by filling to the top of the spark plug hole. The volume of the spark plug hole is 2.50cc (11.20cc is 8.70cc volume with plug installed)
