70cc Ø46mm POLINI cast iron kit for HONDA CAMINO, PX 50 ...

Here is a kit very famous for its strength and its excellent power / torque ratio. This cast POLINI has a Ø46mm bi-segment piston with 10mm axis, a high quality cast iron cylinder has 7 intake transfers and oval exhaust.



Its diagrams and its two-segment piston preserve good torque so that the engine is not hollow at low speed. You will still be certainly amazed at how efficient this high engine is at high revs.



You can mount it with the original cylinder head. POLINI announces the power of 4.8HP at 6300 rpm. But with good equipment (carburetion, variation, admission, exhaust ...) we can get out of it largely 9 to 10hp.



It is really complete because it even comes with a forest to bore the original carburetor jet so as not to be too poor! You can put it with a carburation of 17.5 to 19mm maximum. No need to switch to a large carburetor of 21mm or more on this kit because its exhaust outlet is narrow to offer good engine behavior at low speed! If we want more powerful, we will switch to ATHENA for example!



As an option we offer a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
