    A side benefit of the external filter/pump is an approx 1/2 gallon of extra fuel capacity.

    Thanks for the reply. I just finished swapping out the filters and o-rings, & went for a little 200mile ride. Shes running like a top again.

    Re: the filters, they didn't really look that dirty, so no I'm thinking that the available surface area for the sock filter especially may be just too small? I'd bet a filter of similar width, but with added thickness and length would significantly improve filter longevity and performance. :deal Looks like there is plenty of room for that.


    I'd also be interested in an external pump/filter system. Disassembly and reassembly of the internal unit was not rocket science, but it does take a while, expecially with crash bar removal, etc. I'd be nice to simply detach a few lines and go. :thumbup

    Sorry but the production process is rather bumpy and I cannot predict or give my word until I receive the items in my hands. Sorry about that.
    Cheers.

    Just an FYI. KTM has increased the price on the 990 fuel pump to $540.00 from $495.00. The 690's fuel pump prices have also jumped to $391 for the pre '11 models and to $525 for the '11 and up. So the need for alternatives gets even greater! Thanks for the effort so far from those working on solutions.

    Got the 990 SD fired up last night with the new setup!

    FPR needs to be dialed in, but it runs. That's a plus. It's been so cold and icing around here I'm a little fearful of a new bike with slicks out on the road. Might have to mount up some knobbies, or stud the tires.........

    Thanks. I'm familiar with them. On the 990s, it's inside the tank with the fuel pump. Hence the question:freaky

    Should be up to 38F on Thurs and Fri. :clap If the glacier recedes from the driveway, I'll take is for a test spin.

    Best chance before it's down to -5F this weekend.

    Yesterday I got out on the test bike for a lap around the neighborhood.

    This bike was in a front end crash with a car. 3,200 miles. Front rim is bent - won't hold more than 20 psi when tire is cold (20F). Radiator was smashed - I fit a 950 ADV Radiator in for test purposes. Oil tank was cracked - welded that back up to seal it. Hung the headlight back on with a few bolts and zip ties.

    No point to stick a bunch of money in this as a test "RAT" bike. I've got other ideas for that in the future.

    As long as it runs and is ride able, I'm happy.

    I have more adaptor plates made, o-ring sealed to the tank with pick-up and return line fittings. I'm running a CPR filter kit on the bike so I have room to fit the external Filter, Pump, FPR.

    The FI light is blinking and I need to look it over for vacuum leaks and confirm SAS and all the junk were removed properly once it warms up and I have more time.

    Well...... The bike runs, idles great, revs nice. I let it idle for about 20 min and it was stable. Fuel pump stayed cool to the touch. Fuel lines were cold, so that's a plus. Now it's time to toss on the gear and helmet.

    Remember, Flat front tire with dinged up rim.....

    When pulling out of drive, RPM revved up a bit..... something I failed to check in my excitement. Throttle cable play from lock to lock. I guess something needs a look at when I get a chance. NO biggy for now though. Let see what it's like.

    Well.... It's no ADV. This thing is LOW, and planted, but still has room for my 6'4" body. Steering was very heavy, Low air in tire, but the engine felt nice with a small hick up off bottem. Not sure if that's mapping, with all the mods and screwing around or the NEW FP setup. Straight line, this thing comes alive in a big way around 5,000 RPMs. Front end up...... Ooops. upon contact to ground I think more air got pushed out of tire. Very flat now. Hard to corner. Time to head back to the garage before I'm in the ditch. Big smile though. This is going to fun. This would be a blast at a track day.

    I'm happy with the first ride even with the small issues. New bike to me and this should be a great test bike for Engine and FI mod testing in the future. Easy to do engine swaps and strap down to dyno.

    These are the same rims as I use on the 17" ADV/SE rim conversion so I'll put a new front rim on it when time and weather allows and get out for round 2.

    The Tank adaptor plates are complete and if anyone is interested in one to build there own kit, contact me.

    I hope to have a complete External 990 FI pump kit ready in Spring. This should install and fit very well on a 990 ADV

    It's 10F hear now, so bike is parked until it warms up a bit, at least back to 40F. :freaky

    Please send me an email with what you need and I can try to sort it out for you. Nothing for sale yet, I don't have kits ready, this is all just testing.

    Just got my 990 ADV 2007 home and got one question for you guys. When I turn the key to ON position, I hear a very ugly noise and I'm pretty sure that the fuel pump is making it. Seller left the gas tank completely dry, so I thought this may be the problem. So I put in gasoline to top and let the bike run for 10min, but the ugly buzzing from pump is still the same. I changed my CBR600RR 06 for this 990 and I'm used to clean bzzzz instead of bzshchszshzzshc, or is that normal? :d

    Thanks.

    I don't see anything for sale..... yet :D plus, I am happy to see that someone is working on a solution.

    I am enjoying this thread quite a bit. It keeps me motivated that I can, one day, find an alternative for my internal fuel pump. Plus I don't have the time to do it.... so keep going Craig. It looks promising and if I can help with testing or feedback, I'd be happy to.

    Let's keep testing!!! (and keep up the updates and pictures so that we don't all wonder if any progress is being made:1drink)
