minarelli brn 47mm POLINI custom cut head

custom cut squish head specifically designed for the minarelli v1 80cc polini and other 47mm cylinders too...

these heads have been turned to clean up and re-profile the squish for better performance than the stock BRN head! oh yeah, larger = more fins = chilly head temps.

this one is cut to super street specs meaning it has a pinch more COMPRESSION and is more suited for your super ~~slow~~ ripper setup!

inner lip where head gasket fits = 54mm

for the perfecto head gaskets look no further.

uses short thread spark plugs
