    The stock steel tank only holds 3.2 gallons (US), and doesn't offer the kind of range many of us would prefer. The aftermarket has the solution, with bigger (and lighter, crash-resistant) plastic tanks...
    Which tank has made your life easier? :ear

    Anyone have any comments about the factory inline filter? :gerg

    I'm running the IMS five gallon tank, and I'd recommend it. Mine is translucent, so I can see how close I am to walking. I'd love to fit a Safari, but the IMS is a big improvement over stock, and is much more reasonably priced.

    One caution: if you have the old style IMS cap/gasket, take steps to update it to the newer style. Additives in newer gasoline blends are causing the older gaskets to degrade, leading to little black foam bits swimming in your gas. Not a good thing.

    ditto! to the above but I feel the IMS is sized just right.

    ...and I like the inline factory filter since it's easier to replace/clean out than a pilot circuit in the carb.

    At 3,000 miles my bike started coughing and died twice on a cross country trip. It was about 15 degrees out and I got it home not knowing what the issue was. ADV rider to the rescue, I posted, it was suggested to check the little tiny filter and I found the sucker clogged up with a white gel like stuff.

    Now I run the little red plastic Briggs & Straton fuel filters. My Aqualine Safari tank has two filters and two petcocks. No more issues in the last two years, I need to put some fresh filters on soon. The tank has been fine though, no real crash testing yet. I like the translucent natural tank too, its a very good fuel guage. The huge tank acts like a fairing, it helps in the winter to keep the wind off my knees.

    Added a TM-40 two years ago, love it. No complaints, Procycle had it set up and jetted right out of the box. Comes with adapters installed so its plug and play with the shorter throttle cables that are included. I get an average of 50.20 mpg while touring with a heavy load on the bike and a 14T CS. Mine is runing a stock exhaust and a cut air box with a Twin Air filter. I'm jetted close to stock, one step larger jet for the opened up air box and I love the instant throttle response the pumper gives.

    1+ on the IMS 4.9 gallon tank

    I would also recommend a Pingel petcock to go with your new tank. It's a very well built simple piece.

    Note: I tried a set of tank decals on the IMS.... forget it! They started lifting right off the bat. These are the Kientech ones made for the IMS tank. They even installed them. The fact is, plastic tanks pass gas vapor through their skin and nothing very large will stick to them.

    it's tough to get a filter to work and not disintegrate when using an ims tank because of the fuel line bend. some have successfully rotated the inlet on the carb down w/o it leaking. on my ims i used the stock ims petcock, bought and upgraded larger fuel resistant o-ring and used lock washers on the bolts. it's been solid for 3 yrs. that petcock has a filter and i clean my carb inline once a year so i go w/o an additional one. you can use a locking acerbis gas cap on ims tanks. pro-fill australia also makes a drop-in the neck and leave it there fuel filter that acts as a stage 1 filtration for ims & stock tanks. very usefull for barrel gas in mexico!

    F.W.I.W. as long as the line stays below the bottom of the tank, just buy a longer hose and loop it around the front of the petcock and then back to the carb inlet. A nice wide loop hurts nothing and, if you ever have to drain the tank, unplug the hose from the carb and place it into a fuel can.

    It does seem fitting that a Briggs & Straton fuel filter would work well on a DR 650. Have you tried any other B & S stuff, like cables, air filters etc.?

    I know everyone has their own tastes, but, I think seeing the fuel level is
    the only way to go. After all what the tank costs and what the gas cost you should be able to see it.

    My stock petcock went bad and filled the combustion chamber with fuel.

    For some stupid reason Suzuki doesn't sell a rebuild kit so I called Jesse at http://www.kientech.com/ to see if there was a cheaper alternative to the $89 Pingel and he said to use one from a 660 Raptor, $30. Works great, direct bolt-on. Jesse is a helluva guy.

    Or you can use this ($8.50 USD):

    The one on the right has a pre-bent gas line and the filter itself has a right angle exit tube which works well with the stock carb inlet tube and the IMS tank. Keeps things simple and the filter is easy to get to and change out. (Also, no need to mess with twisting the carb inlet tube around.)

    Some don't like the IMS stock petcock. It is lightweight and 'feels cheap' compared with some others, but after using it for 30,000 miles I don't notice that anymore and it still works perfectly.

    stock tank, cap lock disabled.
    pingel petcock, pricey but non-vacuum, high-quality & no issues.

    I removed the curved metal inlet pipe and tapped the carb for a straight threaded inlet. Works perfect and looks clean. Instructions are in this thread somewhere.

    I prefer the IMS fuel tank.
    By the way IMS also upgraded the flat rubber petcock gasket to "Viton" to resist failure with the new fuels.
    Ive had two of the older style gaskets fail on me and its a PIA to be stranded soaked in fuel.No to mention the fire hazard.
    If you are using the older IMS gasket on the petcock,upgrade now and save some trouble in the future.Part #322141-VITON.

    Im using the Raptor petcock,have the IMS petcock for a spare...hated the stock vacumm unit.

    Just curious what size oring are yall using on the IMS petcock?

    i tried that exact setup they have for the ims tank. same straight filter & all.
    sure it bolts up, but the hose puts angled pressure on the end of the filter.
    over time mine filter has a nice bend at the end from the pressure & probably engine heat. i saw that and yanked it before the filter finally cracked out. ymmv. it's to tight of a bend needed in the hose for the space and the filter takes it in the end.

    maybe the full loop or moving the carb inlet is the only ticket.

    Translucent IMS tank for me with raptor petcock. Check ebay for these as the raptor crowd seem to dispose of oem units in favor of aftermarket shiny chrome. Rotated the carb fuel inlet pipe to the six o'clock position. Now a 10-12" fuel line loops nicely behind the carb and up to the inlet tucking cleanly behind the frame member. Also allows ample room for an inline filter, briggs & stratton if you prefer. :evil

    IMS tank for me with the little in-line filter removed and filter that you see in the photo added- to date, no dramas with fuel supply (carby inlet elbow left standard) or anything-all good

    •TANK PAINTING?From time to time, the idea of painting plastic gas tanks comes up. The bad news is that aftermarket tanks use plastic that is pourous, and allows tiny amounts of fuel vapor to escape. This vapor will eventually lift paint (and vinyl decal adhesive) from the plastic, ruining the finish. There is a method for dying translucent (natural) and some colored tanks from inside and outside, described in this ThumperTalk thread: http://www.thumpertalk.com/forum/showthread.php?t=611365


    •ACERBIS TANK? If 4.9 gallons ain't quite enough for you, but the Aqualine Safari is out of reach, and you don't mind doing some fabrication, the Acerbis 6.6 gallon tank might be what you want. Originally designed for the '92-'95 DR650's, it can be fitted to the current DR with a little work.
