Installed all new power valves last year. Only did around 830km (515 miles). Went to do maintenance on them today and I had one of them 3/4 of the way pulled through. &*%$#! Here is the strange thing, the pv wasn't hard to pull out at all, none of them were. Carbon deposit looked equal on all of them and not to bad.
Could it be that I miss-adjusted this one to tight? Causing the servo to pull hard on the cable, further then its supposed to and wear it down?
Not sure if I should fill the wear part with J-B Weld seeing as the other two still looks new (quick fix). Or send them to YA*AM*A*HEAD for the SS bolt fix...
With all the $$$ upgrades/maintenance I did lat year I though I was done. My father just sold his Venture for an RS Venture and we wanted to sled together during Christmas vacation. Oh well.

If they are adjusted too tight, the servo motor will be constantly pulling on the valve, which will cause issues.
Do the SS fix, or buy a new one. The PV's work well, but the design is shitty........it's what we have to live with.

I have almost 10k on my srx and not on pull through.

Thats what I have done. I sent 4 undamaged valves out to do a "Preventive Srtike". Richard turned them around in less then 24 hrs...just waiting for the mail to get them here!
I also am very interested in the stainless valves, if he gets some fabricated.

Brand spanking new from Yamaha. I use the best procedures. The ones on this site! With some of your pics

The only thing I wasn't sure was when I tried to test it manually afterward. Before closing the two allen bolt back I was turning the servo manually to the full open mark I did. But then your basically puling against the spring. So there is play there. Hard to tell if you have it right.

something went wrong for sure to tight had to be...put a dab of grease in the slot when you put it back together.

Well my good luck continues. @%&$!
I let my pv's soak for 48h in a all purpose cleaner I have at home. It's called Kleenol and is biodegradable. It has been good stuff for around the house and the boat... But look what it did to my pv's. Didn't do much for the carbon deposit but where there was no carbon to start with it started to eat away the aluminum!

Thanks to YA*AM*A*HEAD I have fix pv's with SS bolt which I installed yesterday. I will be able to ride during the Christmas vacation woot woot!
To prevent anyone to make the same mistake as I did, I'm posting a picture of the all purpose cleaner that isn't to aluminum friendly. I know allot of you guys posted that you let your pv's soak in a cleaner to loosen the carbon. Well its a great idea until the APC likes to eat aluminum for breakfast. lol
I bought a big jug as this product does wonders around the house, boat, cars. It is non toxic, biodegradable and doesn't have a strong smell.
Notice is says safe on metals... The only thing close to a warning is the do not let dry on surface bit.

I agree, it has something corrosive in it. If you can use brake cleaner without doing damage than somethin is seriously corrosive in that product.
