Petcock alternative

[JimC]

To those that are interested, I found an alternate fuel shut off for my 99 interstate, the valve I used was designed for the Honda CBR600, 1999 and 2000.    PART # 16950-MBW-023

It uses the same thread to attach to the tank,
It uses the same chrome shutoff valve and extension that the Valk uses,
I had to use the screen from the Valk as the one from the CBR600 is too long,

Best part is NO VACUUM operation, PLUS, the price is only $44, Cheaper than the original, and much cheaper than the pingle (that you have to reach all the way under the tank to use)
To be honest, I am not sure there is a reserve on this valve, but it does have two on locations, and one off in the center.  With an interstate tank I have never come close to needing the reserve.

Nope, the outlet is straight forward, just like the Valkyrie, been using it for over 100 miles so far without an issue

It's MBW,
 SORRY, Jim

Typical in the UK it is £95.76 ($120.74) from David Silver. Still it is better than a genuine Valk one at £228.53 ($288.21)

Thanks for finding this.

I just ordered 2 - one for each Valkyrie in the garage. The OEM petcock on my Tourer left me stranded once, and almost left me stranded a second time. Given I'm firmly in the "Turn OnOff The Gas, Dummy!" camp (and have been forever, since I first started riding) a manual petcock such as this or a Pingel isn't a big thing to remember to operate.

This does not have the reserve

This does not have the reserve

One wonders if a brass tube - similar to the one used with the Valkyrie petcock - can be added to this one, thereby giving it a Main/Off/Res function.

We'll see when they arrive. I have a selection of K&S tubing and can get more if needed.

ETA: The stock petcock's brass tube measures 0.298" (7.5mm). K&S has 7mmx300mm - which I think will work. Maybe as-is, maybe with a slight amount of internal flaring of the first 10mm or so.

JimC,

When you examined this part upon receiving it, what did the section inside the attachment nut look like? Were the exit holes similar to the Valkyrie petcock's in size and position?

They looked similar, but to be honest, the reserve function is not high on my list so I did not attempt to use the brass stand tube in the new one.

I need 2 but just ordered 1 and hope it works out , thanks so much
Well JimC thank you so much, I installed it and just wanted to tell everyone it’s working perfectly for about 500 miles so far, thought I need one for my other bike but found it was just a vacuum leak at the hose going to the petcock and fixed it but the one that I replaced seems to have more flow than the stock one, I always had a little hesitation just off idle and now it’s gone, thanks again to JimC

The "down" on position does feed from the full round hole as does the stock petcock, and the "up" on position feeds from the side cut hole. So if you could fit a brass tube into the manual petcock that Jim found you could have reserve as well. I bought the little lever just in case I could use it somewhere, but as Jim said the stock selector will work on it. Great find Jim.

Have been using a Pingel petcock for many years and find it really easy to access while riding.

Vacuum hose leak on #6 left me stranded once before I knew enough about the Valk.

Also had a hydro lock close call with the stock diaphragm petcock. (added inline fuel filter too)

Simple is best. Never liked the look of that chrome plated plastic petcock knob.

[Bagger John - #3785]

I managed to get the brass tube out of a Valkyrie petcock and into the new one without tools. A little judicious wiggling will free it.

The petcock on my I/S appears to have a very slow leak (1 gallon over 7 months), even though it was rebuilt last spring. As soon as I get the opportunity to pull the tank and switch the valves, off the old one comes.

[jdp]

I just want to thank JimC for sharing information on this petcock, it works better than the original, maybe it’s my imagination but my bike sure runs better, thanks

Ordered mine; thanx, JimC!

[nogrey]

Wow! This is great! Wish I hadn’t just spent $250 for 2 new OEM’s. No way I’ll remember this in 20 years when they wear out. Great information though. Sounds like if you use the tube from the stock OEM petcock, you will retain the reserve function. I see that it has been done, but can you confirm that it does in fact work?

[JimC]

BAD NEWS!

I used my new petcock on my recent purchase, intending to replace it.

Today I tried all the OEM parts houses that I am aware of and they are all sold out, they are now listed as unavailable. If anyone finds a parts house that has one in stock, let me know as I would like to have a spare.

Thanks, Jim

I put the converted one in my I/S tank yesterday. Ordered the Valkyrie fuel screen kit and installed it on the stand tube prior to installing the petcock assembly.

Static tests indicate great fuel flow. Will try a road test with ON and RES positions as soon as I get the pods and carb covers back on the bike.

Revzilla has these $50 with free shipping as well as JP cycles.  I just ordered from Revzilla.  Thanks for discovering this

Revzilla is showing "out of stock" on P/N 16950-MBW-023, and a search of JP Cycles' website returns nothing on that part number. Nor does a search for a CBR600F4 petcock.

YUP,
I have found the same thing. I hope they make another run of these because they work so well.
If not, we will have to keep our eyes open, I am sure there are other makes and models that have something very similar.

I found this by accident as the neighbor kid had his tank off and I noticed the similarity.

I have a couple aces up my sleeve and will communicate my findings to the board at large if my theories pan out.

I bought one last night from these guys and it’s already on its way

https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F163636869582

Still some available. Thanks so much for this option !

[Texcarguy]

Yes RevZilla out of stock but I did order from bike bandits. We'll see if it shows up

[Rio Wil]

Bike Bandit is out of stock....they just canceled my order....

If the photo is of the actual part you get....it appears to be 180 degrees out....the selector is on the wrong side...

That petcock looks to me to be a China copy. It may work, but I still like the OEM parts. I will keep looking or go to a Pingle.
What I like about the one I found is that you can still use the chrome ring and shut off lever, and at the same position as factory. I am sure other options will show up.

[hubcapsc]

There's about five OEM ones from parted-out bikes on ebay now...

[Gnarly]

Really like mine, JimC!
Works like a champ with the original attachments & new AFC-123.
 
Shared your discovery with David Wilder, while he was reworking my carbs. After using the Viton gasket material  to convert several original Valkyrie petcocks to "no-vacuum", he was impressed with this upgrade.

Hope these petcocks are back in stock soon, because now I'm craving an orange & black Standard....

[Texcarguy]

I've now had two different vendors take my order for the alternative petcock, only to inform me a few days later that the part is NLA.  I guess many of these guys don't inventory these Honda parts.. they just take orders then pass it along to Honda NA for drop shipment.

My guess is that this part is truly not available any more.

At the end of the day, I decided that it is hard to go wrong with the original OEM part for our Valkyries.  My own original valve while still operational via vacuum, got to the point where it would NOT turn off the fuel flow with petcock in the OFF position.

I just ordered a brand new, Honda OEM vacuum controlled petcock: 16950-MZ0-033 from ebay (capitolcycle eBay seller) for $113.99 and free shipping.  This IS a part that is currently readily available from numerous sources.  Hardly a huge difference over the suggested "alternative" here, especially considering the wrangling necessary to make it function (changing out the pickup tube and screen, and possibly no reserve option). 

Installation took all of 15 minutes, and removing the old petcock gave me a chance to flush out my 22 year old tank (lots of goobers in there).

Now I have a brand new Honda branded OEM valve with the added safety of the vacuum shut-off that, given Honda's quality, will most certainly last my lifetime.  Well worth the additional $50 spent (and time saved trying to kludge a valve that wasn't designed for this bike).

Sometimes just sticking with stock components makes the most sense!

[TTG53#1717]

So 9 days later my petcock arrived.
It is 180 degrees different and has no marking as to brand or origin.
I guess my exuberance needs tempering.

[Bighead]

My OEM is 22 yrs old and still Works fine. Never rebuilt or tampered with. Think I will stick with it. 

[MarkT]

I've gone to Pingel on George and Jade.  Found you can make the access to the lever better if you JBWeld a paddle on the lever.  For me, still need to be bare-handed.  But I pretty much never need to move the lever anyway on Jade, with a Dan-Marc, belly tank setup as super-reserve, and now an IS tank provides 326miles to the fumes with average 34mpg.  I've never used reserve on George either.  I always shut off the fuel - have to reach it from the right.  I suspect hydrolock isn't a threat with it's single carb and maybe the geared-lobe-type Magnacharger but I shut the pingel off anyway (don't know if that seals against leaking gas).  Superstitious.

[Bagger John - #3785]

Tested my -023 petcock conversion this past week. Works good; flows adequate fuel even at high speed.

There is another similar petcock which caught my attention. The P/N is 16950-MAL-603, and it's the part used on the CBR600F2/F3. I took a chance and ordered one for comparison purposes.

This petcock comes with a stand tube installed. It's 71mm in length (from the edge of the nut to the top of the tube) whereas the Valkyrie petcock's tube is 86mm. The screen which comes with the petcock is 33mm longer than the Valkyrie's screen, and the support boss (where the little rubber stand tube spacer fits) is located where it'll engage the end of the stand tube in its intended application. You can't use a Valkyrie screen set with this length of stand tube, as the center of the screen isn't adequately supported.

There are two options:

• Measure the amount of clearance inside the tank, and if adequate use the -603 supplied screen;
• Remove the stand tube from the petcock, replace with the Valkyrie-specific part then use the Valkyrie screen set.
  

Note that you'll get a little longer range on the main ('ON') setting and a little less range on Reserve should you use the 71mm stand tube. Also note that there may be insufficient clearance in a Standard/Tourer tank to use the longer screen. When next I have a tank/petcock off one of my Valkyries I'll measure the depth into the tank and see if adequate clearance is present. FWIW, both on my F6s have I/S tanks...so YMMV.
