Hello, I have vespa p125x. I have your polini reworked worb5 and i wanted to know if
 i can mount Crankshaft Vespa PX125-150 WORB5 Special-Lip
with the standard rotary valve carb (open to 40mm for polini) to set-up(si26/26g  carb).
Or I can only use Crankshaft Vespa PX125-150 WORB5 Special-Lip with malossi Carburetor kit MALOSSI PX reed-valve, PHB 30mm.

hello,

you can use special lip crank only with a reed block. Since their construction the rotary inlet system won't work (the crank shoulder that regulates the sealing of the compression plate is shaved) so the inlet has to be regulated by reed valve.
