CHINESE Petcock Failure; Anyone else? (Read 276 times)

HondaLavis Senior Member Offline It's nothing personal; the other one came first. Posts: 451 Plano, TX	Re: CHINESE Petcock Failure; Anyone else? Reply #15 - 09/19/13 at 07:27:42 Thanks, everybody. Oldfeller, that makes too much sense, so I did it anyway. I hope this helps somebody. The only internal difference I can find between the cheapo-petcock and the yamaha is the yami uses an o-ring around the valve lever.

Would the "O" ring around the lever have stopped the gasoline from escaping (dripping freely) once it got past the selector hole raised edge nick zone?

If so, you just discovered why the Raptor has the extra "O" ring feature.

Roll Eyes

And you will have documented two good reasons why folks should spend the extra $10 to get the real McCoy Raptor rather than the Chinese rip off petcock, in addition to getting the correct nipple ID/OD that is.

Why lube the rubber parts on all sides with grease?

If the thing is working correctly and sealing off the gasoline like it should, then there are surfaces that will never see gasoline. These surfaces (and the mating metal parts) will never be wetted with anything. So they need a permanent style "sliding lube" like a grease so they can slide easily for as long as possible.

Associated fact about rubber -- it has oil and wax as part of its construction and when rubber finally "dries out" and stiffens it has lost most of its oil component. By supplying the other side of the part with a grease reservoir, the rubber components will last longer before becoming stiff and not working well any more.

By greasing it up good you make it work better and last longer.....

Agreed on the grease part.

This grease will not dissolve in gasoline and is what I would use:

Krytox RFE

Break out your checkbook, however!

It does, however, pop up relatively cheaply on eBay every now and again....
