The Parmakit 187cc long stroke EVO aluminium cylinder kit has 5 transfer ports with a bridged exhaust port. A two piece self centring machined billet aluminium centre plug cylinder head and skull cap and a twin ring Vertex molybdenum sulfide coated piston. The cylinder comes with a bolt on steel exhaust stub. The kit is supplied with an exhaust stub gasket, 4 x multi thickness paper base gaskets and 2 x copper head gaskets to get the correct cylinder head squish with the option of lowering or raising the exhaust and transfer port timing.
A 60mm long stroke crankshaft must be used with this cylinder kit.
The port layout is larger than the original gasket face on the flywheel side casing, so the engine casing will need modifying to extend the gasket face by use of an aluminium epoxy or welding or using a Malossi or Pinasco uprated engine casing.
