Hey Waterman,

It looks like a IMS from the shot you posted. The reason I say that is because the top of the tank where the cap is doesn't look tall enough for the Clarke (I have the Clarke). I have seem both right next to each other and to me your's looks like the IMS.

That's the best I can tell you for now, if I can locate my pics of the tanks maybe I can give you a definite answer.

Another idea is to look in the WR forum for threads on gas tanks and see if someone has a similar picture with the tank identified by brand. The thing I'm thinking about is looking at the section of tank below the rad shroud.

Good Luck!!!

my ims on my 2000 looks different. it could be a different model or the fact that we poured boiling water in it and put the cap on before we installed could change the look.

Well that answers my question concerning my tank. They are identical.

What is the fuel capacity? From what I've read it is only 3.1 gallons.

Is that right? It just looks like it should hold a lot more.

Just bought an 03 and the previous owner wasn't sure either.

STILL CAN'T FIGURE OUT WHAT TANK THIS IS!!!!!!!:thumbsup:

K, so originally I thought it was a clarke tank and bought a cap from a shop, screwed on fine but didn't seal, no mater how hard i screwed it down (much leakage). So I started this post yall all think it's an IMS. I look on their website but the only pics of caps look just like the last one I bought for a clarke. So I buy another one from a shop that oddly looks exactly like the clarke one but slightly different packaging and sure enough....has the exact same problem, screws on fine but doesn't seal.

So I look on thumpertalk's parts page and the pic of the cap available in the tucker catalog for a standard replacement (not billet or anything) looks just like the one that I originally had that broke. So I order it and when it shows up, it is the exact one that I just bought last week (which doesn't work...) and not the one in the picture. So while i'm there picking it up and trying to figure out what the problem is, we call IMS they tell us that while the cap did change, they are quite sure the threads didn't, only the outer part.

So I went back to it last night and double and triple checked to make sure i was getting the rubber insert part in correctly.....tried it super tight, kinda loose, the top isn't warped, threads aren't messed up.....and still won't seal. (to be clear, this isn't a breather hose problem, this is letting lots of fuel out between the tank and the cap).

All I know is that the last cap I had looked EXACTLY like the one in the catalog pic. One thing of note, the threads on this new cap go all the way down inside to the flat sealing face. Meaning, that on this newer one, as the rubber insert is screwed in, one side makes it down to the end of the thread while part of it is still in the thread and not all the way down to the flat surface.

On the old one I had, I could swear that there was a space between the flat sealing face and the termination of the thread and once the rubber insert was screwed all the way into the cap, it was held in kind of loose and and allowed to sit flush against the top of the cap.

I the only markings on the tank are on the top, between the seat post/hook/attachement and the screw for the hold down strap. The only thing is says is "yz # 17"

I've sent IMS an email recapping most of this to see if is in fact one of theirs but they haven't responded.

SOMEONE PLEASE HELP ME!!!!!

ok, scratch all that. i was able to talk with someone at IMS and it looks like it is one of theirs but it is a much older style. they were able to find an old cap and are sending it to me.

if this doesn't work, looks like a new tank...

what happened? did you get the cap and does it work? i just ordered a tank for the same exact problem (with my stocker on a wr250f). actually i ordered both the ims and the clarke to see which is gonna work and fit better. i have two concerns 1) i have moose/enduro eng. rad guards 2) i have a megabomb that might sit too close to the tank.
