i need a few parts to start my 64cc reed valve kit for my vespa bravo. the exaust port measures 25mm with 43mm apart studs, so possibly a puch pipe? also looking for reeds and block for an a35 or the puch polini type, but a set of the stock a35 reeds and block will get me going. also, the intake o.d. is 24mm so suggestions for a carb would help also. i have a 19.19 shb i'm hoping to use.
