Riva Powerbomb jetting help

[JetManiac]

Trying to help an international customer with setting up his dual powerbomb carbs. Anyone have good starting point or advice for working with these carbs?

Ported 760, TL, etc.

I can not help you what so ever, but I do know those carbs are kind of like the original versions of the Dasa Carbs, so maybe you can use a similar setup with Dasa carbs for a good starting point.

I ran Riva 48 PB on my old DASA SS 850 before i switched to 49 FS and i really think the jetting between the two is close.
As Stefan says, he runs the golden FS standard setup 127.5low and 135high, with a low pop off. I had good results with reverse jetting too, 135low and 125 high.
