Dr. Bean's 950 fuel pump kits

Hi,

I will answer all PMs asap.... I Just came back from the Balkan rally:

about the fuelpump: "how it works"

You are almost correct:

1st of all:
The ECU (the electronic control unit, located below the 'glove-box') in the bike switches the power to the fuelpump ON after you turn the ignition key (+killswitch) to ON. It does this through the fuelpump-relais. IF the engine is NOT running, the ECU will turn this power OFF again after 5 seconds, and only ON again when either the engine starts running, or you will turn the killswitch/key OFF-and-ON again.
This is a safety in case the engine is not running, but fuel would be leaking out of the carburetor because e.g. the bike is on its side...

This is all KTM-original, and has nothing to do with my kit/electronics.

My kit is IN the pump and just replaces the function of the contact breakers.

How the pump works:
the pump is a diaphragm pump, which works a bit like a hart.

A coil/solenoid pulls the pump-rod 'out' when it is activated (current flowing through it) and makes the pump-chamber suck fuel IN.
When the pump-rod is almost at its end the contact-breakers OPEN, and de-activate the solenoid.
A spring in the pump now pushed the pump-rod back, emptying the pump-chamber towards the carburetor.
The carburetor has a normal floater: When there is enough fuel it closed the fuel-line. This means the pump will NOT empty and the pump-rod will not run back.
Only when the pump-rod is almost back (spring decompressed) the contact breakers will close again and re-activate the solenoid/coil. starting over the complete cycle.

My kit replaces the contact breakers and:
- detects the position of the pump-rod with an optical detection: activating the coil when the spring is fully decompressed.
- switches the main-current of the pump with and electronic switch (power mosfet)
- includes a damping diode to avoid power spikes, and
- it also activates the pump 1x per 2-to-3 seconds anyway (even if the pump is not empty): this is a safety run mode: When EVER the optical detection would fail, e.g. because it would be dirty, you still get some fuel, enough to run 40mph and get home/to a garage: clean the optical detection and it should be ok again.
Myself, I was the only one to ever experience the need of this, after I completely flooded the pump with mud-water, after getting to s stand in deep water for quite some time ....

Hope this clarifies: feel free to ask!

Looking forward to hearinbg back. Hope the rally was ROCKING!

RIDE ON!

I ordered a kit from Mr Dr Bean awhile ago, just wanna give him some praise. I havent been able to install his kit yet (gonna do it in the winter when I cant ride) but he was super helpful, and the package he sent came quick over to the great white north! Cant wait to try it out either!

Installed the kit two days ago. Pretty easy, and works great.
I was lazy so I instllad the kit with the pump on the bike without disconnetning the hoses, still fairly easy..

Lying on my back soldering is for me a new experience though

Gerben is a nice guy, I have had good contact with him..

Thanks Gerben

I recently Removed my Facet 40171 because from the start, it allowed fuel to bleed through and into the carbs, causing hard starts and tons of white smoke from unburned fuel. This was after sitting for a couple hours or overnight.

I used Dr. Bean's kit on the stock fuel pump and so far so good.



Thanks for all your assistance Dr. Bean.

Hi guys!
I read about this kit on lc8.org (italian site) and bought it 10 days ago.
I mount it yesterday in 10 minutes and now my sm is still alive

The pcb is very well made, like instructions!
The kit is very complete, solder included!

Nothing to add ... thank you Dr. BEAN

Just some tips for installation of my kit

(Most people have no issues with installation, but some people are not always sure they did everything correct and occasional mistake happens of course)

- When testing the new kit on the pump:

* ONLY connect the pump to the original plug on the bike, never directly to the battery (no fuse.. risk of swapping the wires...)​

* The pump will only be activated by the bike for 5 seconds, BUT it doesn't always 'plop' the full 5 seconds: It only 'plops' as when there is actually need of fuel. IF the carburetor is full of fuel, or if there is a fuel-connector in the line (like SM(R)), the pump doesn't pump because there is no need to pump! This is fully normal. Just connect the pump to the bike and try the bike, it will work!​

- Make sure you leave the hole in the PCB marked 'GND' unused!
this GND hole is made for backup, in case the original gnd-ring on the gnd-lead is broken

- Make sure to mount the thin wire coming out of the pump in the SMALL hole in the PCB, marked "S-"

IF it still doesn't work.. don't hesitate to contact me (PM on this forum please); we will analyze the problem together and find the solution. So far every kit ever always worked!

up till end of Januari there will be NO kits available any more (temporarily other prios....).

Mr Bean, I'm a rookie on this whole internet thingamabobber... I would like to purchase a Kit for my 06-950. Could you show me the way to pay....

new stock of kits is ready.

everyone who send me a PM should have received an answer by now.


be aware: this kit is ONLY for 950 with carburator. The injection models (990 and on) have a completely different pump without contact breakers.

Ordered...$$ via your PayPal, Thanks

Finally installed the kit and it worked first time! I was impressed with the quality of the circuit board and the detail in the instructions. I'd definitely recommend this fix.
Here's a pic of the points after 40k kilo's.



Thanks Dr. Bean!!!

out of stock! and Due to holiday season:

NO kits available till 1st of August.

I'll take one when they become available. I'm in Canada.

Thanks!

Me too, please!

Enjoy your holiday, and I will contact you then.

+1

I'll post when I have new ones are available. Please send me a PM by then.

Best way to get the most out of your Ninefiddy. I've tried all of the other pumps and can say Doc Bean's mod with the OEM pump is da kine. Everything else is a compromise.

hmmm...where do I find the link to order?

Hey joker, I put one of these pumps in my 950 about 10,000 kms ago.
One of the best mods I have done.

Just pm dr.bean and tell him what you want.
He is very good to deal with.
