Riva pro series reduction nozzle
Does this nozzle have anything on it saying Riva or any numbers relating to them?
Also did this nozzle always come with the 81, 82 & 83mm rings?
I bought one off Ebay and was advertized as a Riva has no markings and came with 80, 81 & 82mm rings.

Mine does not say Riva on it or have any numbers from them on it. The
only numbers I see is the markings on the rings.
It came with the 81,82 & 83 rings.

The venturi does not say riva on it. It basically looks just like a stock venturi, mainly b/c it is. They have it machined to fit their rings. Should have come with 81,82,83mm rings. There are a bunch of other rings available also if for some reason you need them. I believe that riva even sells them in the .5 sizes...

Iam spinning at 7950 to 8000 rpms now with stock nozzle water temp 84 air temp 94 and altitude 1200 ft Jerry always says sweet spot is 8100 rpms on the RXP so what ring do I need to get there or close?
Stock nozzle is what 83mm I believe?
