Modular Cylinder Head VOCA Race Head RAW, virgin cylinder head, Yamaha DT LC/D - black

Voca Race Raw black cylinder head for Yamaha DT LC/D

The Voca Race Head (blank insert) has completely revolutionized the world of DT and TZR preparations with square cylinder, making an infinite variety of possibilities possible.

This two-piece modular cylinder head is composed of an anodized aluminum cover and a removable blank insert, all accompanied by their respective O-rings. Made from a single piece of aluminum, later CNC machined to achieve this part with a 100% Racing look.

With the possibility of changing the combustion chambers (insert), this cylinder head allows for a different setup for every preference. This insert is recommended for the most experienced tuners, who have a lathe to shape the insert preparation.

Cylinder head:

Having a removable insert offers the possibility to use different inserts depending on the setup. This kit includes a removable insert, which must be shaped and adapted to the piston, stroke, squish, and compression ratio you desire.
It features a locking pin, which prevents the insert from rotating when tightening or loosening the spark plug.

Cooling:

The cooling has been improved compared to the original, optimizing the internal flow and increasing performance. The great innovation of this cylinder head is the possibility to rotate it 180º, allowing the installation of multiple radiators.

• Right side, use of one radiator
• Left side, use of two radiators

For high-performance setups, the use of two radiators is recommended.

Temperature sensor:

The thread allows the use of the original temperature probe. We also offer aftermarket sensors for use with digital gauges, such as the Voca Racing gauge. For digital temperature sensors, you should use Koso, Stage6 sensors (M10x1mm) and pay attention when selecting the plug color (black or white).

Gaskets:

Another of the most important features is the replacement of the original simple gasket with O-rings. They ensure greater sealing and reliability.
Gasket kits are available as replacements.

The kit includes:

• Black cylinder head cover
• Blank insert
• O-ring gasket kit
• Water connector
• Anti-rotation locking pin
• Assembly instructions

High quality product, Voca 100% Racing!

NOTE: The internal diameter of the insert before the O-ring is 61 mm!! Therefore, all modifications for pistons over 56 mm in diameter will already be too close to the gasket, which may cause gasket damage, loss of compression, and coolant leaks. Make these modifications at your own risk.
