I feel dumb for even posting this, but what the heck, it's winter and I can't ride.

Sometimes I take my 2006 YZ250F on trail rides, and I'm afraid of running out of gas if we end up "deep in the woods", or if we were to take a wrong turn or two. I have no gas gauge, so if I ran out, I would just be out, somewhere in the woods. Now granted, I ride with friends, and they would help; but wouldn't it be great if I could "run out", then switch to reserve and at least get closer to a road, or closer back to camp? For riding motocross, I could just leave it on reserve.

In 2006, the WR still had the steel frame, so you couldn't just buy one of those year's petcocks for your 2006 YZ250F (the fuel line comes out the "wrong" side). Maybe you could make it fit; I didn't want to try.

Now in 2007, the WR gets the aluminum frame, and wahoo, I can just buy a 2007 WR250F petcock for my 2006 YZ250F (this would probably work for a 2007 YZ250F too, but I didn't test it). You don't actually get any more fuel; just a warning that you're going to run out.

This is what my fuel switch looks like stock.

Here is my technical write-up of said installation.

1. Ascertain what tools will be required
http://www.westsideridaz.com/days/2007-02-19/1%20-%20technical.JPG

2. Remove old petcock (remove those phillips-head screws)

3. Compare 2006 YZ250F stock to 2007 WR250F stock. You can see I get about an inch or so of fuel level to go when I hit reserve.

4. Switch the fuel line over to the new petcock

4. Install the new one (like I said, I feel dumb for even writing this up; it couldn't be easier, just a bolt-off, bolt-on affair)

Here is what it looks like on the bike. No fit issues that I could see.

I put gas in it. It didn't leak.

(sigh) only five more weeks until spring...

[RangerCharlie]

good info

[five21racing]

How much was the WR petcock?

Good info. x2

[Johnnybmoto]

Good write up... Wonder if I could work something like that on my CRF

[av]

Good job :thumbsup:

[xracer48x]

if its not leaking, it should be fine. I like the anniversary edition yzf.:thumbsup:

[Jaycycle]

Huh, cool idea. Yeah how much was the wr petcock?

Is the WR tank the same size as the YZ?

[tranqwhl]

It was like fifty bucks from my dealer! Not super cheap. You could probably find it cheaper, like here at TT.

I don't know if the WR tank size is the same.

Here in MN we got up to 45 degrees F yesterday! I guess that's why I kinda got "spring fever" already.

I rode my XR100 on a (frozen) river on Sunday, and I had to use my reserve tank. It's a nice feature to have in that situation. I stopped pinning it everywhere, and just tried to cruise home leisurely (trying to conserve gas). I got home no problem, but it was nice to be able to "run out", and know that if I took it easy, I could at least get closer to home.

I know the 230F's have reserve's, and maybe the 450X and 250X's do...

Nice writeup!

[RhinofromWA]

I had a similiar search while setting my RM250 up with a desert tank. Here is the meat of my posting in the RM 2 stroke forum.

OK I have found out some things.

I don't have measurements for you but apperantly a Husky reserve will work. I stopped by a friendly local shop and was talking when I thought to ask to see one of their petcocks. Same mounting holes but the face of the lever was pointing a slightly different direction.

Then as I went through another shop I asked if they had any petcocks and they had a Acerbis "universal" reserve with similiar mounting and another valve face configuration. Price like $18.95

Point is they will work..... Next question is if the on/reserve will be enough to get you back to camp etc.

I think the "not on new suzukis" attitude has to do with the new aluminum paremeter frames on the 4 strokes. The petcock is mounted to the frame and it would be near impossible to have a reserve circuit run from the petcock into the tank and be practical.

Rhino

the RMZ's have the petcock mounted to the frame not the tank and a hose runs from the petcock to the tank. That would make a reserve (a 2 stage tube set up, see your pics above)

$20 bucks is better than $50! :thumbsup:

[ktm rider32]

Nice!

[tranqwhl]

I actually looked at my receipt, it was 43 bucks (with tax, I rounded up).

[xr50er]

were could I get one for cheap lol I want it just so I could get back to my truck when I run out at the track lol

Can you post the part number for the 07 WR250F's petcock?

They don't have the 07 WRs or YZ250Fs listed at the official Yamaha web site. :confused:

http://www.yamaha-motor.com/sport/parts/home.aspx

[av]

The Australian site had the manuals for the 06 & 07 YZ250Fs:

06 YZ250F's manual. (http://www.yamahaownershandbook.com.au/lib/download.php?f=5XC-28199-32.pdf)

07 YZ250F's manual. (http://www.yamahaownershandbook.com.au/lib/download.php?f=5XC-28199-33.pdf)

The 07 WR450F's manual is here, (http://www.yamahaownershandbook.com.au/lib/download.php?f=5TJ-28199-44.pdf) but I don't see the part number for the "fuel cock" in there anywhere...

[jjgixxer]

I'm going to be putting my clarke 2.6 tank on sometime this weekend. I ordered 2 06 wr 250f fuel petcocks so I can change the way the lines go. I'm not sure yet how I'm going to run the fuel line on the right side.:excuseme:

[av]

Hey tranqwhl, now that you're home, don't forget to post the part number for the WR's petcock...

[tranqwhl]

I just grabbed the receipt now! :)

5UM-24500-E0-00

FUEL COCK ASSY 1

(by the way, why don't we universally just change that to "fuel switch" so I don't feel weird describing what I've done to my bike every time .)

;)

[250Thumpher]

FYI guys, Yamaha of Try has Microfiches on practally any Yamaha product...

Thanks dude. Now we know you're riding a male bike instead of a female bike... :p

Checked there... No fiche for the 07 250Fs yet...

[YZ250F06]

That's awesome. Even at the track, at least when the reserve runs out you just go back and fill up. Better than running out on the middle of the track and getting exhausted from pushing your bike back up a hill to get the gas.

Good info.

[lotten454]

that's rad, i'm gunna have to go buy me one of those

[250Thumpher]

06... 07... Same junk :busted:

Nope, 07 WR fiche has the petcock's part number that I need - can't find the 07 part fiche for the yzf or wr anywhere... :excuseme:

[250Thumpher]

DOH!

My bad

[tranqwhl]

Have you tried your local dealer? These guys, who I got mine from:

St. Boni Motorsports
952-446-1554

..said they physically got a fiche from Yamaha for the 2007 WR.

[250Thumpher]

I hate going to the dealer and looking at fiches (the people at Easy Bay Motorsports are friggin NUMNUTS!)

I prefer looking at one, and giving them the part numbers, so there are no errors. YOT has the older bikes, but apparently not the 07's yet...

[250Thumpher]

Also, North County Yamaha has a fiche as well, but not the 07 yet either...

[osheen]

If you have all that time and can't ride, why don't you wash that roach. I couldn't sleep at night if my tank was that dirty underneath. I certainly wouldn't be taking my petcock off with all that dirt and scum in the area either.

I'm just anal.
