my viper has 1237 miles on it and I decided to clean the power valves tonight - I had a hard time pulling them out of the block they were so gunked up. Now they are clean and I pumped out the last quart of Yamalube from my sled and put in Amsoil Interceptor. I shall check again in 1,000 miles and see if that's any better - I guess the Yamalube will have to go in the golf cart and the weed wacker - cause it aint going in my sled or my boat.
 
did you just get the sled? left over ?
if not I think you need to clean your vlaves aleast once a year!
of course that just me
 
yeah i wouldnt blame the oil, i'd blame the maintainence. the electronic valves are far more susceptable to carbon build up than a gas operated system. i clean mine 2-3 times per riding season i try to never go to 1000 miles before doing them (750-800 miles max) if you warm the motor up to temp prior to pulling them, you loosen the accumulated deposits and the valves slide right out. you can also double check the oil pump settings to make sure you arent over oiling and causing more trouble for the valves. and you can use a product from yamaha called "ring free" that works very well on 2 stroke powervalve motors to reduce carbon build up. ski

A broken power valve thread here prompted me to pull my power valves and check them for the first time in 3000 miles. The machine has had nothing but YamaLube 2-S. All three valves slid right out and scraped clean with only a few minutes each with a sharpened tongue depressor. I was thinking after that that I'd never use anything except YamaLube...
 
Personally, i find vegtable oil works really well... plus the sled kinda smells like french fries afterwards.

I run nothing but yamalube in my sled and have never had a problem with the powervalves gumming up. I check 'em every 500 miles or so.
 
I just pulled mine after 5400, that's right 5400 miles and the slid out no problem. Except for a little buildup they were fine. All I ever used was Yammalube. If it matters, this sled was run 90% of it's miles in Canada at sustained high speeds
 
Sled was new in January 2005 - 0 miles, so maintenance is not the issue - I pulled the PV's as I just had a friend bull the PV's off his F5 (4500 miles all amsoil interceptor) and they were spotless, and I mean spotless. I will pull them in about 500 miles and see what they look like.
 
Contrary to what oil retailer's would like you to believe. Excessive carbon build-up is mostly caused by improper oil, fuel mixture setting's and the type of use the engine is operating under. (low rpms/low load/cold motor vs high rpms/high load/warm engine.

What Mtnviper is tring to say is you ride like an old ladie, Crank it up a notch, and the PV's won't get so gummed up.

At least I can ride faster....

you'll always be a prick!
 
ok...so my SRX had 2800 miles on it and it had on broken cable and the other 2 cables got yanked right out of the valves they were so stuck. So I am thinking oil pump is set rich? Funny yhring is the sled still ran pretty good. Only thing I noticed was the R's woyuld not hit 8500 all the time...but for the most part they did.
Why are some motors NOT having all the build up? I ride it hard in the UP and it saw all 22 miles of lake Goegibic last season and I was not easy on it. So why am I getting SO MUCH build up then? I mean it was oozing out of the gullies where the spring housing meets the valve housing when I took them apart. It was like tar on the valves and the housings. Only thing that would clean up the mess in the heads was goo gone, a ton of Q tips and a lot of paitence. 1 cable and 3 powervalves and 4 hours later It's back together. I ran Yamalube for one season and Amzoil the second. First time the valves were pulled.
???????????
 
I always set the pump on the lean side of the spec, 21.5 mm gap in the cable. It's seems to help. I clean the valve's 1-2 times a season, so far no stuck valves. Rich jetting can also cause carbon build up, because the oil is mixed with the fuel at the fuel pump. So when you add fuel your also adding oil.

new sled, rode most of last year, put away without cleaning valves, may have contributed to the excess difficulties of cleaning and gumming of valves. your also comparing apples to oranges with an f5, higher mileage, higher revving sled, different oil, different jetting, and oil consumption. just an observation.

and without saying yamaha has a bad pv design, i just want to point out again, the electronic operated pv's have more oiling, cleaning, problems than a gas operated non electronic system in my observations. the electric valves need more attention.

i am not sure why some srx's and vipers are cleaner than others or why some cable ends pull through while others that were "more abused" (ie: less maintainence) remained active and in good working order. all i can think of is the different riding conditions, storage, and oil pump settings makes all the difference in the world.

after i understood the problems i was seeing with the build up on the valves, i adjusted my maintainence schedule for them, as my oil consumption was where i wanted it to be. now like i said i wont go over 1000 miles without cleaning them. when you up the maintainence schedule, the cleaning takes about 45 minutes from start to finish, and you have piece of mind they function and are clean. ski

Based on my experience, I'm going to put power valves on my maintenance list too. Every 3000 miles, without fail.
;)!

At the rate I am going if I were to wait until 3K, I would be buying new valves and cables every time.
i just don't get it...

Tempted to turn down the pump...
Might have to do some looking into where it's set at. It don't seem like it uses much oil. Nowhere near what my friends riding Cat's use...so I am uneasy about tuning it down to much.
