Reduction nozzle use on RXT/GTX
Anyone use the Riva pro reduction nozzle kit in Jerry's store
on a 3 seater????
Want to get some input before I plunk down $340.00
Could these be used to adjust for air/water temps as opposed
to changing out/ repitching impellers?
Thanks for any input

You will get the best top speed when you pitch the impeller to run max RPM's with the 81 mm ring.

I have it on mine and found I get the best speed and throttle response with the 82mm ring. Which is also reccomended to be run with the stage 3 setup. I hated the 81mm ring, I lost speed and accelaration, it just felt like a turd. Each ski is different so what works on one doesnt necesarily mean it will work the same on another. I noticed about 20 RPM difference between each of them. 83mm 8140, 82mm 8120, 81mm 8100.

unless Riva got their head out of the ARSE do not order this part for a RXT or GTX,
I ordered one for my RXT-X (same as RXT) and they sent one for a RXP I called and was told this is the only one they have so you must remove OPAS (most do) and drill and tap 2 holes for the steering nozzle
I could have just ordered at the wrong time and talked to the wrong person so please just ask before you spend the bucks

i have just fitted the RIVA pro-series reduction nozzle today to my RXT-X with no problems, fitted perfectly & no alterations to be made, i live in UK & bought the parts from 4 Tech performance on this site along with all other mods listed 2 weeks ago, cant fault em !
i to was looking for what difference each of the rings would make but after reading this thread i guess i will just have to try em all & see whats best,
(will be testing with speed gun next weekend & will let you know results)
