Riva red jetting specs

From the horses mouth for a single carb wb1 701:

Is that with a stock f/a or a/m? That will make a difference in the pop off.

Paul Lehr is who was gracious enough to give the jetting specs for my last 96 B1. It was ridiculously spot on.

Yes, I asked for specs for a stock as a rock single carb wb1 @ sea level.

Hopefully this helps others. Of course elevation and other mods will effect this but it’s a start.

That pop off is really low. That must be for a a/m f/a?

I suppose it’s possible. I asked for stock setup. 20 psi does sound low. You’re probably right about the aftermarket f/A. I think factory pipe setup is based on having aftermarket f/A’s. Maybe the same here. In any case, it’s their tune for anyone looking for a stock baseline.

You still need to power tune the top screw.

Is this the jetting for a stock motor, or with a riva red pipe? I know it says stock in all the other comments but in the subject line on the email it says red pipe?

Those specs are for a stock motor with a Red pipe.

It will not be lean. It may hydraulic but it will most certainly not be lean at those settings
