VHM cylinder head for SHERCO SE 300 from 2021 to 2025. Two-piece cylinder head: body and interchangeable combustion chamber insert.
The VHM AA33205 cylinder head is designed for SHERCO SE 300 from 2021 to 2025. A VHM cylinder head is made up of an aluminium body and an interchangeable insert that forms the combustion chamber. By swapping the insert, you set the engine's compression and character to suit the fuel and the terrain, without modifying the head.
Key features
- Two-piece cylinder head: body and interchangeable combustion chamber insert.
- Compression adjustable by swapping the insert, without removing the cylinder.
Specifications
- Brand: VHM
- Manufacturer part number: AA33205
- Engine: 2-stroke
Who is it for?
- Original head damaged by pinking (detonation), cracked or warped.
- You want to match the compression to the fuel, the terrain or a tuned engine.
- You're after a smoother or snappier engine without changing the cylinder.
Good to know
The insert is chosen to suit your engine and your fuel: a smaller chamber volume raises compression, which may call for a higher-octane fuel. Always check the squish when fitting.
Fitting tips
- Clean the cylinder mating face without scratching it.
- Fit new O-rings and grease them lightly so they stay in place.
- Check the squish (gap between piston and head) with solder wire before riding.
- Tighten the head in a criss-cross pattern, in several stages, to the recommended torque.
- Fit a new spark plug and refill the coolant.
