Hello, i have vespa VBC with stock 2-ports cylinder and the head. The cylinder head doesn't have squish band, so the compression ratio is very low, about 1:7,4 according to the manual book. Here is my cylinder head look like > imgur*com/a/oDwBTau My question is, can I use another cylinder head with big squish band that looks like this > imgur*com/a/GyOzMKg with stock cylinder and small taper crankshaft? the compression ratio of this cylinder head is I think around 10-11:1 with 57 mm stroke.
