I just cleaned my power valves again, I clean them after every time out! But this trip was around 1200 miles, and them things were like pulling teeth! Just wondering if anybody else is having this same problem, or if it the oil I am using? I am using Phillips 66 Injex, I have been using it since day one, but seems to be getting worse and worse to get them darn things out of there each time! This is on a 04 Viper S by the way! Just wondering if I am not alone here? Thanks in advance!
 

Maybe that is my problem, I have been trying to use this oil up and switch to something else, but I bought like 4 cases of this stuff a couple years ago and am still using it!
 
Maybe you should check your oil injector adjustment. I have been riding an SRX & a Viper for the last five years and the power vales have always been well lubricated and rarely need cleaning when I did take them apart. :rockon:
 
Riding style is a huge factor. If your on the pipe a lot with higher rpms and loading it harder the valves will be open more and wont collect as much carbon. The higher exhaust temps of higher speeds also make it burn cleaner. Also, warming the engine up before pulling the valves makes them come out much easier. ;)!
 
Thank you all for the great advise, I tried the warming up idea, and it didn't seem to work any better. I finally got all of them, but I don't like tugging on them as hard as I had too, to get them out. Just wondering if it was something I was doing, or the oil, I might just go ahead and switch oil and try it. Do I need to burn all of what I have in there out, or will it hurt to mix a little of it? Thanks again!!!

in response to your question of if you need to drain the old oil before adding a different brand.......I have always been told that you only need to do this if you're switching from a synthetic/semi-synthetic to a non synthetic oil......was told that if you mix the two together they will "gel" up......not sure if its ever been proven.....or substantiated......just what I have been told. I ran Yamalube for the first year I had my SRX....and had some problems with deposits on the valves......switched to the A/C VES oil for the Cat powervalved motors......and had an even worse problem........I talked to a marine mechanic.......he suggested running the semi-synthetic yamalube made for the watercraft engines.........since I've been running that I have absolutely NO problems with deposits on the valves....or with the valves sticking. Not sure what is so different about this stuff......but it has definately worked for me.
 
Wreckless, that is pretty weird that a semi-synthetic would not carbon up as much as a full synthetic, but I have seen stranger things! I also want to point out to all of you that, when i say everytime I go out and ride and come home and clean them, it is a good 1000 to 1300 miles each time! So just wanted to clarify that, also! Thank you all for the suggestions and pointers!
 
If you're going to change oils I wouldn't recomend Yamalube for pv engines.Mind you this is my opion only but there are much better oils out there now that don't smoke as much and leave alot less deposits both synthetic and petroleum based.As a matter of fact I thought Phillips was one of the better ones but you never know until you try it in your own personal sled with your riding habits ie throttle inputs and jetting.I tried Wynns when I first got my SRX but it was way too rich of an oil and kept fouling plugs but it worked fine in my 700 VMAX;just goes to show it could be a variety of things affecting how an oil burns.
 
i think 1200 miles is beyond the service interval for cleaning powervalves, no matter what oil you use - injex isn't very good and yamalube would be better. i run amsoil interceptor and noticed my valves to be a little easier to clean on the faces but, the round part with the bushing is still gunked up. I understand if you sled is jetted stock that contributes to how clean the valves are. Mine is stock and I have to clean about every 800-900 miles.
 
2 Smoke!

Just an observation here Rob, but when I was a 2 smoker, we used Injex for the full 6k+ miles we rode those Vipers, cleaning the powervalves twice a season, and we never had a lick of trouble getting them out. They didn't jump out of the sled, but they werent a cast iron b!tch to get them out either. Maybe you're just babying that sled too much (hahahahahahahaha!)

We followed Erics advice on setting up the injection, warmed 'em up before pulling the valves each time and they usually slid out pretty decent. I think the first change was actually the hardest, since we went almost the whole season before we cleaned them (and we didn't lean out the oil pump right away either...)

Mark has been saying he's having trouble with his PV's this season as well (01 SRX)... Maybe the age of the valves themselves is playing a factor (expanding or pitting, retaining more residue/gunk, etc...)

You can always go pick up an Attak... :) I love checking my oil, and not having to carry it...

I agree with you Mook, it would be alot eaisier to just check the oil and go!!! How you guys doing? I hope all is well, we are planning on going up over St. Pattys day, are you guys going up also? Talk to you soon, Rob
