Cylinder kit and crankshaft Top Performances Racing 86cc 44mm Derbi D50B0

Description

Solid tuning kit with cast cylinder with mini chrome liner, 7 transfer ports, 50mm bore, split cylinder head and a full 86ccm displacement. Also included are a full-flanged crankshaft with 44mm stroke and racing crankshaft bearings. All the small parts and seals required for a smooth assembly are also included in the kit.
All components are matched to one another by the manufacturer! Install, tune the carburetor, done !! With the right exhaust system and the corresponding carburetor, the output is around 20PS.
We definitely recommend using a tuning exhaust system that is suitable for this Big Bore displacement class and a larger carburetor. A 24mm carburetor is ideal. In addition, due to the large cylinder liner on the motor housing, some material has to be removed / milled in order to be able to insert the cylinder. Notes on this and assembly instructions are included and are available for download from us.
