replacement manual petcock pn#
« on: August 22, 2018, 07:43:47 pm »
Not seeking debate or argument, as i know what I like already.Had this same issue with my little kawasaki sherpa 250 with the crappy vacuum petcock.Bought a brand new oem yamaha manual petcock for an XT-250 that bolted right on in about 15min for less then 20 bucks. I've read so many forums for my new to me C-10 and can't remember where I saw the post but can anyone confirm that the manual petcock for a yamaha 660 grizzly quad is a bolt on replacement for 25 bucks??  thx

Did a little search for you. http://forum.cog-online.org/concours-c10-zg1000-general-chat-and-tech/replacing-petcock-just-remove-and-install-a-new-one/ It looks like Strawboss and Tim have used a yamaha petcock. Don't know which one.  Maybe they'll chime in.

Yeah, the Yamaha bolted right in on mine but a few here said they tried and it did not.

I went to look at the Eagle Mike site... don't know if he pulled thru his cancer problems, but there isn't any further info on his site, about the petcock.
OK, my '82 KZ lists the same Kaw part # valve as my 2001 Concours, same. The KLR part number that I found for the 650KLR is the same with the exception of an "A" suffix #51013A. The Yamaha part I received bolts up directly to my '82 KZ, EXACTLY. Maybe different years KLR used a different valve? Not sure, but I solved my fuel leaking problem with a part that's made in Japan. Sorry, I don't have the Yamaha part# handy but I can get it if you need it. Here it is.

I bought one, too, and it did not match up on my 2005.

The Yamaha petcock that he was selling for the KLR clearly stated in his pages that it would not fit the Concours. The packing slip when I got mine (for the KLR) stated the same. Issue is the hole spacing.

I'm not convinced I want to install a manual on my C-10, but interested.

I don't know if the petcock for a Yamaha 660 Quad will fit or not.
But, they have them on Ebay for $6.15.

https://www.ebay.com/itm/302033516914

At that price I bought one just to see if it fits...
   {If it won't, it should fit my old Yamaha Dirt Bike}.

Interested to hear how this turns out. Assuming the hole spacing is okay, it looks like its length may cause it to collide with the valve cover. If it clears, that length would probably put it down where it is easier to get to.

I have no issue flipping a petcock ON and OFF. I've been lucky (I guess) with the Connie petcocks not allowing burbles of air to to let enough gas to flow to fill a cylinder, or two. That wasn't the case with my GPz. I had two of them fail and just plain leak filling cylinders on numerous occasions. Trying to head out in the dark to leave for work found me standing in a puddle of gas. Fortunately, none of the cylinders lit off and the starter didn't have enough grunt to cause any damage. After the second one failed, I fiddled with it enough to where gas wouldn't flow in either ON or RES, and just ran the bike on PRIME - the vacuum de-nutted. When I shut down, I just put it in one of those two positions and never had another issue.

I replaced the one in the KLR with the Yamaha version because the OEM petcock took a crap on my way home from work one night. Left me stranded, but was fortunate enough to catch a ride with a fella in a P/U. Figured out what the issue was once I got home. IF that one had a PRIME position, I could have gotten home okay without the lift.

So yes, please keep us informed.

(after I ordered) I noticed the length too, but figured it was worth a try.
Some of the photo's in their add: show the long one and some a shorter version.
                                                  some are shown with strainers, and some without...

Will wait and see what arrives.


NOTE: On Ebay, there are several sellers that have the Petcock.
          Different sellers offer different lengths.

Ride safe, Ted

Thx for taking the chance. If it fits and functions well PM me your address and I'll be happy to pay for yours and mine.For 12 bucks the piece of mind is well worth it. As I said the yamaha one I used on the little 250 Sherpa fit like it was designed for a kawasaki. thx again Ray     By the way I'm the proud owner of a new to me 2004 black(kindof) C-10, 12,000mi. runs like a finely tuned swiss watch, Can't wait to start spending all of my retirement checks on doodads.

Thanks for the offer, but not necessary.
I can use it on my dirt bike if it doesn't fit the Connie.

Another interesting tidbit.
The seller I bought it from is located in Humble Texas.  (That's about 30 minutes from my home). 
    Only going to take about a week to get here...   :rotflmao:
So, I could go see him and ask about models with different lengths or bolt patterns.

By the way; I'm about 90% sure this petcock was made in China...

I'm sure the 6 dollar ones are chinese, but I'd guess the OEM yammies for 16 dollars are most likely chinese also, but with some japanese QC thrown in for good measure.

I use stock petcock that I rebuilt with a external fuel filter and this manual inline as backup. Love it!

No in tank filter. Also have carb bowl tubes and replace needles on floats when necessary.

Alcohol in fuel hardens them. Use Lucas fuel treatment and Marvel oil every other tank also.

We have Good news  :great:  and bad news  :-[

The Petcock arrived!!  / Hole spacing is far too narrow, and hose nipple on wrong side for use on my old dirt bike.  :-[

I'll send the supplier a note and ask if they can help us.

UPDATE: The supplier said that none of the petcock's he has; have the correct bolt hole spacing..

Ride safe, Ted

PS: I like Lee's inline idea.
           That way, I can't forget turn the gas off, but I could turn valve off and run gas out of carbs when parked for long term.....

have had an inline on mine for over a year, but used a full port motion pro style one.




rode the concourse to the vintage gasser drags last weekend. had gf on back, in the counrty on a few long roads topped 115 for a few miles straight. it flows fine.  $15.89 fix.

Visually distracting perhaps. Could be run under somewhere. But I like the reminder. I never forget fuel tap now. Actually looks worse in picture than real life.

having used on bikes, many permutations of fuel filters like this


and this





I would never again use a plastic body filter, every one I've used failed within 3 years, and dumped fuel during it's failure...
That said, I don't use any external filter anyways, so if I did, it would be the glass/metal construction like in the last photo..

as for the shutoff valves, everyone says "High Flow", when in reality, how much flow can you get, thru a barbed fitting, with an I.D. that allows a 1/4" hose to connect to it...?

not saying it isn't enough flow, just making a point that the flow i.d. is "just enough" not High Flow... :rotflmao: :rotflmao:

I am also very impressed with the cheapo shutoff valve I use on my Snapper mower, really cheapo one, that has lasted 5 years now (and I installed it because I had a float needle that didn't want to seal, but it was an all metal float needle and seat... like a Mikuni carb in old days had... how did those work soo well? hmmmmmm...)


not saying I'd use them on my bike tho...

 :)) :)) :))

you get 1/4" diameter inner port. that's full port in the valve world. std port is quite a difference.

sintered bronze cone element filters are an issue with rusty sediment, they will pack in with fine particulate and not flow. the flow rate actually sucks even 100% clean especially on a bigger line. use a screen filter.

ive seen a glass filter break, and the result was not pretty. ill never use one on anything. ever.

this filter:
https://www.milfordpower.com/R10423-1-4-Line-90-Degree-Fuel-Filter-with-Poly-p/r10423.htm

please note: 5/16 OD. 1/4" id. listed as 1/4" filter. plenty.

have run there for many years. replace every 5 or 6.

yeah...

Internal filters seem to distort at base as they age and allow fuel to bypass on the three tanks I have inspected. I have broken a glass filter on road trip. Had o-ring seal issues too. To hamfisted for glass I guess.

Never had an external plastic filter fail. Have tried a few that did not flow well new however. Some just are too restrictive for gravity flow. I always check by observation into a gas can.

I have a 5/16 external petcock. 3/8ths are available as well. 5/16 th flows fine.

As said prior, like the whole affair, filter and tap in plain view. Something reassuring in light of hydraulic lock issues on these old bikes. Also allows inspection of fuel debris at a glance.

Like tires, fuel filters and manual taps are a luv affair where the beauty is in the beholder perhaps would submit....he he!

Not an issue at this point. It's shifted to the rear as far as it will go, and I will knock down the thickness of the intermediate mounting block when I get a chance. Have some other things I need to take care of first.

Can't tell from the photo.
Is the petcock your using shorter that the one I purchased?
Mine is 1.55" {bottom of the base to centerline of the nipple}
