Mini cylinder head kit (K100 8 valve)
The picture shows a Mini engine with a kit installed.
This kit contains all of the used BMW motorcycle parts usually required when converting your A series engine to the BMW K series DOHC cylinder head and fuel injection, eg: head, cams, valves, rocker cover, injectors, throttle bodies, throttle position switch, fuel rail etc.
Kits can be tailored to your requirements eg. with different cams, or without injectors if you are using carbs. Please call to discuss your requirements.
Parts are supplied in unmodified, used condition with a limited 6 month warranty.
We can also supply any additional new BMW motorcycle parts you require for the job e.g. valve stem seals, shims, studs etc. A 10% discount will apply to any new parts bought at the same time as the kit.
We offer full after sales advice and support in regard to the BMW side of the project. Companies such as Specialist Components can supply the special (non BMW) parts and Mini expertise required to complete the project e.g. cam pulleys, seals, belts and head gaskets of varying thickness to alter compression.
