RE: Welcome to Club SAITO !
Pearlhead:
If you use a velocity stack, make sure you place a gasket between the carb body and the stack body. When you buy a velocity stack, it does not come with a gasket and there is a small space between the two bodies that needs to be sealed. If you don't do this, the stack will not be less effective. I don't know why Saito doesn't supply this gasket with the stack but you can use an o-ring or fabricate one from a faucet washer. There have been many comments made about this matter on this thread.
