*manifold is fixed with 2
The all-rounder among the 130cc racing cylinders from POLINI is not only available with a crankcase intake but also as a double intake. This intakes simultaneously via a crankcase intake and a reed valve intake on the cylinder. This means that the fill level increases and also the performance and possible top speed. We stock the matching intake manifolds both for the DELL‘ORTO SHBC 19.19, and the DELL‘ORTO PHBL 24 (both with stud connection, depending on model with 2 and 3 hole attachment). Please note: The geometry of the dual intake manifold means the cylinder can no longer be raised.
Conclusion: Double is better. Optimum cylinder filling due to dual intake system.
SIP-TIP: GRAND-SPORT piston ring (e.g. part no 75020110) and MMW cylinder head (e.g. part no 38543800) mean the dual intake is ready to race.
