    I looked at it. It looks like the Immix rack may have the same problem as the TCI 'Borrega' rack mentioned above where it mounts to the subframe side would interfere with the Wolfman rack mounts I have. There might be a way around the wolfman racks using spacers or washers, but that would mean buying the Immix rack and taking a chance that it will work. That is why I will probably go with some type of mounted top plate like the Happy trails or Automotive machine shop rack(so far).:ear


    Yes Pantah;
    That is also what I'm interested in only I was hoping they would have more attachment points across the front and rear(never to few points:lol3)

    I get by fine with the stock tank, but am considering the 3 gal model just to switch from steel to plastic to save weight.

    >"While I am on a posting frenzy, I have some thoughts on carrying extra fuel. I have been seeing a lot of people posting about buying these bigger after market tanks, and consequently having plenty of issues with them."

    3.1 Gallon IMS tank doesn't have any fuel problems, replaces the stock tank. The low fuel light comes on with .5 to .6 gallons left in the tank, in mild dual-sport, that's about 160 miles to low fuel, and probably 190 or so to tank-out. I carry a 1 gallon rotopax tank on mine too. I could probably get by with .5 gallons in small bottles, the gallon of extra fuel was useful though for other bikes!

    The 4,5 gallon IMS tank needs a vacuum pump to draw fuel from the lowest reaches of the tank and spray it up on the fuel pump.
    I have heard a variety of problems with them, i.e. not pulling fuel from the bottom of the tank. But I dunno, there are lots of people running them... hopefully a couple of them will post up here.

    Timely. I was going to start a thread, but the discussion is right here right now! :1drink

    I just pulled the trigger and cut the deal for an immaculate '09 WR250R with 1900 miles...commuting to work miles! :clap

    Bought it for the CDR next August and other trips.

    What do you say, 3.1 gal tank or 4.7 gal tank?

    I have been thinking I need 220 miles+ range for one part of the CDR. I could do that easily with the 3.1 gal plus my Kolpin 1.5 gal extra. And that way, I could leave the Kolpin off for trail riding, or when I do not need the long range. Last year I rode the WABDR and the distance between gas was < 90 miles.:D

    Obviously, the 4.7 has the RANGE for big trips. But as alluded to I was wondering about possible problems not to mention the physical size affecting trail riding...:huh

    Had the first run of tanks with the old style o-ring. Once that was updated no problems. In Baja I might pak a 1 gallon rotapax along but usually don't need it.

    IMS 4.7Gal the only issue i have had is that it touched the radiator guard(standard one) when i put it on but with use it must have swelled in that area and didn't touch any more......then

    I went and got a Flatlands racing radiator guard as some people said it wont touch :huh and it now touches FFS

    so i put a bit of heavy MTB tube cut to shape in there with zip ties and its not an issue.......for now

    other than that the only real issue is trying to get that Farkin fuel hose off the bottom of the pump when i want to work on anything:cry PITA

    and yes i can use ALL the fuel in this tank

    No problems whatsoever with mine. So far 3.1 capacity has been fine for my use, however I do have a kolpin can for longer trips if that should ever happen. The original tank was just too small, and I did not want to carry a gas can regularly.

    I bought a 3.1 IMS awhile back. I've had no problems, it mounted easy and doesn't make it any more difficult than the stock tank with regards to removal and unplugging the pump. The stock tank was just too small with my daily use. The IMS has made it much more manageable for the day to day work. I did get the Wolfman rack setup w/ a rotopax for that extra gallon if I ever need to use it.

    You just need to look at what use you have for the bike. Will a large tank be better for your typical day or would something just a bit bigger than stock suffice? Only you can answer that.

    It could happen......I'm considering it.

    She's powerfully improved, spot on perfect, race ready for adventure in every way. Wonder if anyone would be interested?

    You know I love her. Just ain't riding her much lately, as my Berg is still hogging my attention and coaxing me toward the enduro circuit. Been camping off my F800 the rest of the time, over much longer travels.

    It's been a great project and a mighty fine ride. Might be time to say goodbye. I never thought the day would come. Definitely the best bike I've ever owned to date.

    In my case it is a resounding "yes". I will concur that I had some concerns about changing the fuel system but in my case I went with the Safari which has a pretty good record and minimises the changes (e.g. keep the stock pump and add a fuel pickup to pull fuel out of the wings). At the time the IMS tanks were new or still being designed so I never looked at them.

    The Safari looks pretty good on the bike and aside from noticing my knees were a little more spread in the seated position than when I had the stock tank, I didn't feel there was any difference with the handling even when the tank was full. As a bonus, due to the wings you get a little more crash protection over the stock set up too ...

    For me 14L was still not enough for the most recent trip so I supplemented it with a 4L fuel bladder. With this I feel my safe distance is 400kms although I have done 377kms on just the Safari before I chickened out and used the bladder.

    Personally, I would definitely go for a larger fuel tank over the rotopax on the back of the bike. On my long trip I was already carrying a lot of weight on the back (especially when I had the bladder fuel and strapped on top of my soft luggage) and the handling was fairly poor once I got onto some of the sandy roads I experienced during the trip. But then again the Safari tank is a fairly expensive option ...

    I have the IMS 3.1 and I've had no issues......I also have a 1 gallon Rotopax for longer trips.......

    FYI - Rotopax now makes a 1.75 gallon can that's more attractive for use than the old 2 gallon can which was waaay too long to mount on the back of your bike......I have ample range with the 1 gallon but might consider picking up one of those cans for a BFE/Baja Run......same locking hardware as 1 gallon since the depth is only a half inch deeper.

    If you're not using it.....blow it out......make some room in the garage for the NEXT project......

    You took the WR250R project far and allowed a lot of folks to ride your coat tails to gain insight/tips

    Thanks buddy :1drink

    Thanks for the input guys. I am no where needing more fuel anytime soon, and when I do, it will be a random trip here and there. With that said, 95% of my annual riding, is my normal weekend riding, and for that, the lighter, the better. That is what is making me lean towards having a very easy way to have the extra fuel when I need it, and not have it, when I don't.

    For most of my weekend riding, its east coast single track..dodging trees every 3 ft. The less sloshing gas, the better. The KTM 300 EXC was supposed to become the dedicated woods bikes, and leave the WRR for more dirt touring, easy riding duty. BUT, KTM's being KTM's, it has spent as much time in not running condition, as it has running condition. :lol3

    My Safari 3.7 works well and I think the lifting pump will pretty much drain it. I took 3.6 gallons at one stop last September.

    Re: Rotopax -

    How safe are they in a crash? I have entered the Alcan5000 for 2014 and the rallymaster won't allow them for safety reasons. I need 170 miles fuel range and I'd like to ride my 690R. Since 170 miles would be a stretch I was planning a Rotopax using the Wolfman rack mount. It puts the tank on the side of the bike. Anybody fall off with a Rotopax? Any issues?

    I only really need a gallon. Rally Raid has a 1 gallon rear tank that would work but it is $600!

    I think a Rotopax would be the last thing to give in a crash, they are tough. The rallymaster is just not wanting to open the door to extra tanks, let one in then you have to make an argument about every other gas can.

    That's my experience as well. 90+ mile range on the stocker was basically letting me get to my riding areas and have about 20 miles of fun before starting to frantically look for gas.

    The 3.1 basically allows you to be less frenzied about seeking out gas on your normal type rides. The extra 50 miles is a lot when you consider it's 1/2 the range of the stock tank right there.

    Appreciate the kind words. Indeed, it was quite a project. Spent over $10k when all was said & done. I enjoyed seeing what I could achieve with it Man, she sure does run mighty fine now. I've put about 2,000 miles on the Big Bore and it's all been really good. Total miles on bike is currently 10,600.

    I remember there was'nt much interest in the WRR when I jumped in way back around page 30 in this thread (Post was in the 500 range, if I recall correctly). Been amazing to see how this thread has grown with contributions from so many. Our WRRdualsport.com site continues to see a tremendous number of page views. Glad all the effort has been so helpful to so many.

    A lucky someone is likely to snatch a very impressive machine, unlike any other. Maybe I should hold an auction. Hhhmmm....

    One of these days, i'm gonna come do a CORE ride! And yes, I do have a new project in mind. Another real good one! I'm kind of itchin to get started..

    P.s. Serious private bids welcome via PM, if interested.

    P.s.2 Someone recently posted Yamaha was dropping production on the WRR. Any truth to that? I've not heard this before. I looked on Corporate site and see 2013 models still listed for $6,690 msrp.

    Sometimes you just gotta move on. I've been spending the last week doing some of your mods. Even though you are leaving the WR fold, I hope you can keep your site up for others to use - it's been quite a resource.

    Hate to say it...but I bet you'll miss selling it someday after all the hard work you put in on that bike and site. But sometimes a new project is what your soul needs RIGHT NOW!
