MPL Molnar Manx 90 Bore Specification
All parts are machined from original castings to ensure authentic appearance.
90mm bore x 78.42 stroke = 499cc
Pressed up crank assembly, with integral mainshafts, made from EN36 forgings hardened and ground all over. 40mm parallel pin and INA needle roller big end bearing. Titanium or Carrillo con rod. Alternative one-piece EN40 crank with Carrillo con rod.
Special forged 2 ring piston, running in a ceramic bore in a lightweight barrel casting. Maximum safe RPM = 8,200.
Revised and updated compact combustion chamber machined from castings made from original Norton patterns. Inlet valve 2” diameter. Compression ratio up to 13:1 can be achieved but the efficient combustion chamber design allows the use of 100 octane unleaded fuel. Minimum carb size 1.1/2” (38mm). Single, near central spark plug with twin spark option. Revised detail machining of cambox castings to allow for improved cam profiles and neatly enclosed valve springs.
Almost every part has been worked on to reduce the weight of the engine to 78 pounds (35.5 kg) excluding magneto and carb.
For countries where it is permitted, this engine can be supplied 2mm oversize on the bore to give 92mm bore x 78.42 stroke = 521cc. The extra cost is £300.00
