Rusty valves on my RXP
I did some wrenching on my seadoo last week. I checked the exhaust valves through the exhoust in the cylinder head and they are started get rusty. So I need to replace them before they fails.
I can replace them with new oem from 2006 + or go with a set of ferrea ?
My setup is:
SS wear ring
Rotax racing ECU
blow off kit
Free flow exhoust
What would you advice me to do ?
What are your opinions on Ferrea valves ? do they rust too or ? what about their performance ?
My ski is a seadoo RXP 2006

I put ferrea valves in my conversion this summer. They are a very well made valve. They are stainless steel so they will not rust. I have heard the 06+ OEM valves from the dealer are very expensive. If i were you i would buy a new set of Ferrea Valves. Make sure you grind or lap the valve seats before you install them otherwise you may have sealing issues.

yours shouldnt be rusting since you have the updated 06+ valves... maybe im mistaken though...

hang on, is the rust on the valve stem or on the base of the valve? A little surface rust on the base isn't a big deal, I would try to clean it up first. If it's on the stem, that's another issue. you have an pics?

Are you sure it's even Rust? And not just deposits on the valves from use?

I have tried to turn the engine, while watching the valve and it is not only the surface that are rusty. The rust is eating the metal so no doubt the valves need to be replaced.
I spin arround 8600 rpm with my setup and I know that it doesn´t last long with stock valves, valve spring and retrainers.
Can I put in a set of bran new Ferrea valves with my stock valve springs and retrainers, or do I need to put in a pair of Riva springs too ?
i think that the valve springs are very expensive and would like to advoid these but don´t know ?

You definitely need the springs and retainers bro.
