What tank does everyone recommend? I think I'm leaning toward the IMS.

I've had the IMS 4 gallon tank on my 02 XRL for five years and haven't had a bit of touble with it. I did buy an XR600R petcock for it when I installed it since the adaptor IMS supplied to use the XR650L petcock looked a little hinky to me and the XR600R valve bolted right up.

I have the 4.0 IMS. It bolts right on no prob. My engine's pretty tricked out so it only gets about 80 miles to the tank before reserve.:thumbsup:

I have the clark 4.0, much slimer than the 4.7. I have been happy with the tank, but I did have to make an extra support for the front to make it solid on the bike.

I have the IMS 4.7, no problems at all. Everything lines up perfectly and it is much slimmer than the Clarke tanks I've seen.

+1 for the IMS 4.0. went on no problem and havent had any problems at all in over a year. actually feels narrower to me than the stock tank. :thumbsup: kinda wish i got it in natural instead of red so i could see the fuel level easier though.

I have the 4.0 Clark and couldn't be happier. The 4.7 looks to big and ungainly to me, and most of that extra isn't available unless you tip the bike over and slosh it to the petcock side anyhow.

Here is a picture of the Clarke 4.7 installed on my bike. I don't notice the size of the tank when I ride at all. The fit and finish were pretty good.

I just put an older IMS 4.0 on my XRl. The petcock is hitting the cooling fins. I have dremel clearanced them a bit but it needs more. Anyone else run into this? WC

The IMS 4.0 comes with two mounting brackets that bolt up to the forward frame under the dipstick. Not sure how the Clark mounts. I didn't weigh the both of them empty but the plastic seemed lighter than the stock metal.

I'm on my 3rd IMS 4.0 on different machines....no problems at all. The petcock on the current tank I have, comes pretty close to the head, for sure. Manufacturing tolerances, perhaps? I thought I would have to grind a bit of the cooling fins, but it hasn't caused a problem in over two years.

Ihark thats why I went with the XR600R petcock, it bolts right up to the tank and saves about 1.25 inch.

I'll have to give it a try....I think I have one of those laying around, from a previous project. Thanks for the tip.

My petcock (stock) is very close to the fins. It makes me wonder. On one of my lawnmowers the fuel filter was too close to the exhaust causing vaporlock.
I never sit in traffic because I live in B.F.E.:thumbsup: I wonder...?
Maybe the 600 petcock would be a good idea.

Mine is very close, and I haven't had a problem. Summer temps here can get into the 90's with high humidity, not every day, of course. I thought about the same thing, after mounting the tank, that you did. So far, so good. (I'm crossing my fingers).

Here we call it "east BF North Dakota".....no offense to the North Dakota folks. I'm not sure who coined it, but I know I've heard it for at least 30 years....

Yes Malevolent73,
