Here's a real hottie: the SERIE PRO racing crankshaft for the Vespa 125 VNG/GT/GTR VLN2T -> 145900/Super/TS VLN3T -> 18138/150 VBA/VBB/T4/GL/Sprint/V VNB1T -> 2942593/Super VBC1T -> 412373.
WORB5 lengthened the intake timing of this shaft on a MAZZUCCHELLI basis. Puts a lot of punch in your tired old original motor. Higher rpm, improved acceleration and higher end speed are possible. This racing shaft harmonizes very well in connection with 177 cc racing cylinders and touring - race exhaust systems.
Conclusion: very good and simple tuning for your weaker, original motor.
