[Blaster bob]

I am looking to buy a carb for my blaster It has a +3 veto's crank 240 Vito's big bore kit that I am sending to KOR for head work and port work also have V force 4 reed cage and spacer I was thinking of a 38mm but don't know if that will be to big if some one could point me in a direction that would be great

What is going to be your intended use?

unless that's a drag only build, avoid the 38mm
33-36mm keihin pwk would be my choice
