Cleaning YPVS

[EricMichael]

I talked to my local yamaha dealer, asked him about adjusting the power-valves and he said they have some substance there that you put in your gas tank called Ring-free or something and he said it does a real good job and cleaning the valves. He said to still have the valves adjusted atleast once a year using this stuff.Anyone have any input on this stuff on whether or not it works well?Thanks

no one has heard of this stuff?

i use this stuff but when i pulled my valves out this year i still had lots of carbon. i guess i was better off than some since i didn't need vise grips to get the valves out.

i use seafoam which is a similar product to ringfree-- i think it helps a lot, but they'll still need a manual cleaning and adjusting. i wouldn't let them go more than 1500 miles without at least checking/ cleaning them. although some sleds need it at 1000 miles, some could go 2000-- depends on how you drive it, oil type and consumption, etc. i readjusted mine before this season and you could really tell the difference-- motor just sounds and runs crisper and smoother. .02
