Crankshaft -TAMENI Racing -
Serves e.g. as a conversion shaft with 51mm stroke / 97mm conrod for your Vespa PK50XL to be able to drive a 133 cc cylinder. The intake timing is longer than with an original shaft, which increases the degree of filling. This allows higher revs depending on exhaust and carburetor type.
The crankshaft has the oil seal with 20mm on the alternator side and therefore a thicker cone than e.g. PKS, V50, PV, ET3. Who converts to an electronic ignition, should access here directly to prevent a tearing off of the cone.
