Description

Here they are finally available, the latest BIG EVOLUTION thermal units from POLINI MOTORI. This model with its Ø47,6mm, it offers no less than 69.94cc real torque and power! POLINI surprised us a lot with this high engine ... Between the kit, the pot and the crankshaft without even mentioning the admission ... POLINI hits hard in this series named BIG EVOLUTION! This cylinder preserves the magnificent cooling system of the well-known evolutions ... Named CLOSED DECK. The cylinder is a really worked model. It has 6 admission transfers and a huge model exhaust bar. To better release the power of this monster, POLINI has reviewed the exhaust duct on the rise with a good venturistaion, the exhaust now comes specifically with a large flange 3 screws (delivered with the exhaust). The piston is a mono-segment model, reinforced light alloy, POLINI branded ... The cylinder head is also very specific with its cooling system CLOSED DECK, quenching, external and internal machining ... Really impressive both in performance and aesthetics ! In addition, a lot of accessories are delivered to you like the bolts of nuts, the studs lengthened, the joints to make the squish, the arrivals of water machined in mass ....


Reminder : bore Ø47,6mm, for original stroke diagrams 192/129 °, compression ratio 15: 1. You will obviously need to be machined in the housing to put this cylinder! We have greatly depreciated the finish and the small tricks as centering pins breech automatically posed.

 

We recommend at least to accompany this kit : crankshaft reinforced connecting rod 85mm , variator POLINI EVOLUTION 9 rollers, carburation 21mm with valves BIG EVOLUTION , Pot POLINI Big Evolution, extra reinforced bearings ...


Optionally we offer a stage 1 preparation, this preparation is a modification of the channels and exhaust light by increasing the diagrams and improving the pipe, it increases the performance of the cylinder. An improvement of the piston and skirt stocking is also included in this modification. Allow a little extra time for this preparation!
