05 rxp vavles
my 05 has about 177 hrs on it and i am looking at starting to boost the performance a little bit. it has a stage one kit and soon to have exhasut and opas block offs. i then will be doing an x charger, external ic and 42lb injectors. my question is when do i need to start upgrading my valves? before those mods, after or not at all. do i need to just do the head studs, springs and retainers? or vavles as well?

stage 2 and about 200 hours... so far... I was planning on it this winter but I would say earlier is better... there is known problems with these valves soooo.... saw a set in the classifieds too...

As long as you aren't adding a after market ECU to raise rpm's and it has held up this long I would think you are good to go!

replace your valves asap, 05 exhaust valves are prone to rusting and snapping!

I recommend replacing them regardless, with Ferrea or Seadoo 08+ . There are many cases from ppl that baby their skies and these valves still fail. This should be the first mod on a list before adding any speed performance mods.

The 05 valves are hollow and WILL break.Get them out if you if you want performance.
Also the Ferrea valves are junk . They break quicker then 2005 valves. 2008 and up
only way to go.

If i had 200 hours on motor no way will i not solidify my bottom end like drag cars you dont to top end fresh without doing bottom end but on a budget go for it dice sometimes roll your way

i am no baby to my machine i am always on throttle only time i let off is when it comes out of the water i dont hold it wide open to hit the rev limiter. from everything i have seen the only time to modifiy the valves is when you use an aftermarket ecu that allows the engine to rev higher and can possibly get the valves floating. but that is more vavle springs then valves themselves
