About Us
Situated in a workshop in the centre of Holland near Amsterdam (30 km) and Utrecht (20 km), Harm Klijn is the only specialist on the continent who is fully specialised in the repair and reconditioning of the Lucas MK-I and MK-II mechanical injection system, as fitted to the Maserati Sebring, Mistral, 3500 GT etc. as well as the Triumph TR-5 PI and TR-6 PI ( MK-II ).
We are proud to have succeed in improving the reconditioning MK-I and MK-II system for the various Maseratis and Triumph sportcars. Even though the components have remained unchanged, many technical improvements has been made!!  Specialization: We are specialized in the reconditioning to the highest standards of: - Injectors - Metering Units MK-I and MK-II - Petrol Pumps - Pressure Relief Valves - Inlet Manifolds - Check and recalibrate Metering Unit MK-I and MK-II. - etc.

For all types:
It is very important that the 'Vacuum Diaphragm and vacuum chamber are in good condition!! It is a vacuum controlled system, so it is very important there is no leakage in the chamber!! Also the efficiency of a vacuum injection system depends largely on the inlet manifold. A vacuum leakage in the inlet manifold is often caused by worn spindles and butterflies. This results in the malfunction of the Metering Unit's supply of petrol to the injectors, causing exessive fuel consumption!! All parts of our manifolds are manufactured under our personal supervision and are especially made for each individual manifold and partly hand-made!!

Conversion:
At the time 2 different Metering Units and 2 different inlet manifolds were produced for the Triumph TR-series. It is possible to convert a CR type ( TR-6PI 1973-1975 124 HP) to a CP-type (TR-5PI, TR-6PI 1968 up to 1972 160 HP). If necessary we can provide you with all instructions needed for such a conversion (adjustment engine and distributor). Just fitting a complete CP-injection system to the engine is not enough!.
