    Manx Norton 500cc Road Engine
    Product Description
    The 500cc road specification engine from Works Racing is built to the same exacting standards as our race engine. In fact it shares almost all the same parts too. The only differences are in the compression ratio and cam design. It also comes with a very neat solenoid actuated decompressor valve to aid starting. The result is a more docile engine, but don't expect ES2 levels of tractability.

    If the owner wishes to upgrade a road going engine to race specification, this can be done with ease - It is simply a matter of removing some shims from under the barrel and fitting race cams. The engine is an exact re-creation of the final 1962 specification Manx engines made at Bracebridge Street, but benefits from a myriad of detailed improvements. These improvements are aimed at increased performance, improved durability and oil tightness.

    The improvements include:
    One piece crank shaft with modern racing big end shell bearing - for improved crank stiffness and smooth running.
    Double row ball timing side main bearing - as used on original works engines.
    Extra wide needle bearings on drive side - for extra crankshaft support.
    Cross braced piston - for improved durability.
    Cylinder head ports machined on 5 axis CNC - for optimised air flow and increased power.
    Combustion chamber is fully machined - for accurate squish control.
    Uprated oil pump - for improved lubrication.
    Nicasil plated cylinder barrel (no liner) - for improved heat dissipation.
    Lightweight stainless steel valves - for reduced valve-train losses.
    Fully enclosed valve springs with o ring seals - no need for messy silicone.
