The enthusiasts dreamed it, POLINI did it, the famous POLINI SERIE 6000 kit remade for your old ZUNDAPP engines. This kit is really complete, it has an exhaust pipe internal diameter 29.5mm and external 32.20mm.
An intake pipe with its flexible sleeve internal diameter 19mm, external diameter for rigid carburetor of 24mm, and diameter of the flexible sleeve of 35mm internally for flexible carburetors, if you install a flexible carburetor with this sleeve, you will cut the intake pipe at the entrance, its diameter will then increase to around 25mm.
It is ideal for the installation of a 25mm POLINI, DELLORTO PHBH, PHBL, VHST ... The cylinder is in high quality aluminum with nikasil coating, it has 2 rear transfers which are also used for filling the lower engine which the laterals will then be fed. It is therefore ultimately a real 4 transfers because the 2 rear does not come into action for the PISTON sweep unlike the AM6, DERBI ... The exhaust is a large oval.
The housing inlet skirt diameter is Ø52.9mm, so a 53.1 or 53.2mm reamed housing is required. Between axis of the studs 46X46mm. The piston is a model with high silicon content, with segment in L. The delivered cylinder head has a very worked combustion chamber, hemispherical, micro-blasted finish.
It has a reinforcing bar in the mold to prevent curtains. In view of the quality of aluminum, do not be afraid of cooling, this cylinder will not exceed the temperature required for performance! It will give you a lot of torque and power when you start afresh with your good old ZUNDAPP motorcycle. It is really a superb set that has emerged POLINI, in limited series! Have
