opening venturis
I am investigating opening my venturi's on the center and end carbs. Bigger cam and heads going in and I think a bit more CFM will be a good thing.
I assume to do this I need a cone shaped grinding stone, but can't really seem to find a lot of options on diameters out there. I I think a 1 3/8 for the end carbs, and maybe a 1 1/4 will be a small adjustment for each based on current measurements. So two questions:
Does anyone know where I can source these size stones? and
Any tips on mirroring the venturi proportions once the narrowest part is opened up?
