Description
The VRH cylinder head from Pinascois not only the ideal addition to the 177ccm cylinder kits from the same company.
With its central plug layoutsimilar to the Vespa T5 cylinderit ensures optimal and ring-free combustion. The layout provides for more symmetrical flow conditionsand more powerwith simultaneous decreasing temperature, which is very beneficial for the air-cooled two-stroke engines.
Due to the thick material thickness it can be further processed very well for other racing cylinders of the brands Polini, Parmakit,etc.or in connection with long stroke shaft conversions.
Material composition and processing are at the highest levelfor long life and thermal stability.
The cylinder head cover must be modified for the spark plug hole.
cylinder head nuts must always be tightened step by step crosswise, preferably with torque wrenchwith 1.8-max.2.2kgm.
