I am switching my 250cc 1 cyl. Italian made 1960 Moto Parilla Road racing bike from it's 30mm Del Orto carburetor to a 30mm Mikuni. round slide. Upon attempting to make my own V. stack for has occurred to me that you folks may just have the solution. If so please let me know ?

Hi PJ -

Great bikes! Looks like a labor of love!

I don't have stacks for the mighty 250, but I could help dyno test on a real EC997 dyno (aka - "not a dynojet") - It would be fun!
