Somehow related...

I found out that I can make it prime by blowing into the tank's breathing pipe.
That trick is so old... I'm pretty sure I'd forgotten about it for at least 20 years. Thanks for the reminder of a good, quick and "clean" alternative to the messier, clumsier methods of priming Carlos.

Was able to find the 2 outlet version of the Adventures fuel pump thru Heeters Performance Centre at 1/3 the cost of the OEM unit. Also the rebuild kit for $10. I had a feeling that the KTM price was a little out there, kinda like there spin on filter VS the Hi- Flo, both made in a factory in Thailand and Hi-Flos can be had at 1/3 the cost.

Gunner,
Was the correct part # 11-7903 for their rebuild kit for the square pump.
Just trying to pin down what to order as a spare kit for traveling.

Bill, I believe Heeters part# for the rebuild kit was ET-79-1103, close to your #.

Took the new pump apart for comparison to the oem unit, I noticed a couple of differences. The KTM pump has a helper plunger spring on the main diaphram and a spring and ball bearing stopper on the inlet, also the main diaphram is a rubber material as where the two outlet pump has a clearview plastic diaphram. I installed the rebuild kit to see how it would work in the oem pump:I reused the rubber grommits for the check valve diaphrams because the ones supplied in the kit are longer. Put the clearview main diaphram in place of the stocker and put the pump back together. I hooked up my remote tank and fired up the bike, it ran fine with gravity so I set the tank on the floor below the skidplate, no noticeable change. When I reved the engine I could see the fuel speed up in the clear line but the pump could easily keep up. So it looks like the kit works fine but I don't know if the clear plastic diaphram will be as durable as the stock rubber unit when the spring loaded plunger is pushing on it.

Fuel Pump Rebuild Kit

Another option is to have your local dealer order the kit from Parts Unlimited. You'll pay tax but no shipping. They don't sell directly to public.

These pumps are also used on various ATV's and while the PU website is not too helpful, if you're dealer calls they will gladly help out. (Even my crappy local worthless Albuquerque KTM dealer/mechanic could handle this task........only after I gave them the part number of course.)

Mikuni part #: MK-DF52 (is whole rebuild kit)

http://www.mikuni.com/c-fuel_pumps.html
(also lists individual part #'s if you need a specific gasket, valve, etc.)


Price was < $13.00

Cheers,

I'll update this a bit... The rebuild kit I installed over 2.5 years ago is still going strong.... I was wondering if the clear plastic diaphragm would hold up but many miles {flexes} later it's still moving the fuel with no noticeable change... I carry a spare rebuild kit on longer trips just in case....

Bit O/T but what's the nominal ID of all the fuel pipe on the 640? Looking at getting some filters from parts unlimited...

KTM 640 Mikuni Fuel Pump

after my original fuel pump stopped working. I purchased this pump:
http://www.aircraftspruce.com/catalo...ifuelpump1.php

which is 14L/H while the original is 32L/H
however, since then the CARB is pouring fuel. when I connect the fuel line directly to the fuel tank it works fine. I even replaced the needle of the CARB float and it didn't solve the problem.
Any Thoughts?

ERD,
Not sure I understand what you are describing, anyway, did you replace the O-ring on the float needle seat.
