Petcock replacement options

[EmeraldCityRich]

I’ve spent over an hour trying to answer my questions. Maybe my search technique sucks, but I could not find a Sticky Note nor specific part numbers.  Since I know Petcock maintenance is an issue for all of us, I thought it might be an easy find.  My apologies if I missed it.

I want to replace my stock Petcock with a positive shut-off, no vacuum, Petcock.  Please advise if either or both of these work and which would be most like the OEM design:

Pingel P/N 1311-CH. $142.95 Amazon
Honda P/N 16950-MAL-603. $72.99 Amazon

Appreciate any advice- or another option if it looks/functions like the original Petcock

I don’t need the vacuum line.  Has my Valkyrie for 23 years and can’t remember ever not turning the Petcock off after riding.

Cheers from central Texas

I had the same dilemma.
I've now replaced it with a cbr600 petcock without the vacuum.
It does have a longer filter that, when fitted, touches the top of the tank, but that's of no concern as it's plastic and will not be a problem.
The brass "tube" is shorter so you'll get slightly less "Reserve" but so what.
One of the big advantages of this petcock compared to a Pingel is that you get to keep the ON, OFF, RESERVE Dial on the side at a handy reach.
All you'll need to remember from there on is ALWAYS turn off the petcock when stopping. That, for me, is now done automatically.
I've gone a step further and have recently also desmogged the bike.

Plus one for the CBR replacement regarding compatibility and ergonomy.
You can transfer tube and strainer from the old Valkyrie petcock to the CBR, just in case you didn't know.

If it boils down to reliability only, there's a clear draw between the Pingle and the CBR petcock.

If you want to keep the vacuum operated safety,  just add a snubber into the OEM vacuum line  and you won't have to service the OEM petcock again.
Cheaper, simpler to install and less prone to fail than adding a DanMarc for safety.
The latter working well enough, though. (just to pacify the DanMarc-believers )

Best,

A years-ago post about vacuum valves indicated.... With the selector "OFF" and the bike not running, fuel would not pass through the valve, regardless of the diaphragm condition.  Was this correct?

Yes.  That assumes that you as the rider are careful enough to be sure you have dropped the valve into the "off" notch.

If one is going to carefully and habitually turn off the petcock every time the engine is shut off, the OEM petcock will serve just as well as a non-vacuum replacement. 

Additionally, the OEM petcock can be converted to non-vacuum a LOT less expensively than purchasing a replacement.

A big difference between the OE petcock and a quality Valve is that the OE is made from what I call “pot metal”. It’s rather soft and wears way more than equipment made from better material. The OE valve does it’s best WITH the vacuum working and NOT functioning it all the time. The problem is you can’t tell WHEN the diaphragm stops working properly and  now it’s just ON all the time. Same with the switch side, WHEN the switch wears out from constantly turning it off it can be ON no matter the setting.

Pingel is a fine piece of equipment and if you get the non vacuum one it can withstand functioning it hundreds of times over many years without wearing out.

Thank you, Sir.  Owning a well-used Triumph many years ago got me into the "off habit".  Forever.

I put on a Pingle back in '98 as I had 3 different OEM petcocks fail within 6 months of ownership...

I also went "old school" and mounted a Pingle.  I did not know, after 100 years of Motorcycles.......that it was so hard, to just turn off your fuel these days????

Im sorry you went through that tough experience but it is unusual.  Ive had seven Valkyries over a span of 19 years.  I had one petcock failure and that was a failure that caused no fuel to be passed through.

Getting a Pingel is head and shoulders above just disabling the vacuum side of the inferior OE petcock. Turn it off, done! Exactly.

Once upon a time, a motorcycle accident meant gas all over the bike and road.  The engine could remain running after the bike was hit and knocked over. 

Honda gave us the "tip over" switch to shut off the engine.  The vacuum stops, closing the fuel valve.  Fuel in the tank stays in the tank.  A correctly maintained vacuum valve has this advantage.  Honda probably considered this when they designed the Valkyrie.

from what I have read, the vacuum shutoff was a FED regulation that started somewhere around '80-'81 for gravity fed fuel systems.

Got my petcock from Amazon: MOTO1988 Fuel Valve Petcock Gas Tank Valve For HONDA CBR600F F4 CBR 600F F4 1999 2000, best about it is there's no vacuum to worry about.
