The 650 Dakar Thread

[Seventh]

Had some free time today to take the bike apart. The short of it is I didn't find anything wrong with the harness, so I pulled the injector and am going to replace it. Here's the vid:

Is that a standard 2004 BMW F650GS injector? It doesn't look like the one in the manual. If it's a replacement, does anyone know the make and part number?

@divimon2000, i don't seem to see the circlip, mine might have fallen off. Worse comes to worse, the sidestand switch seems disabled. Went through the visible harness and it seems okay. I pulled the injector, and it seems to have some crud in it. I haven't touched the coil yet.

@WayneC1, thanks for the instructions - checked the common chafing points, and didn't find anything. I can't seem to find the diodes, will check the manual.

@baams, thanks, that doesn't seem to be it - jiggled the wires and no GS death. I haven't taken the ignition assemble apart yet though.

@jpkailua, nope - it still dies with the gas cap open.

@everyone, appreciate the help. Will let you know if a new injector fixes things.

The injectors are standard items, BMW use Bosch and the Bosch No should be on the unit, there are cheaper aftermarket units. The 650X shares the same unit as the GS and the X runners are fitting a higher flow rate unit to improve performance with some good results. There is a thread on advrider about the tests and results

The Part No's (BMW and Bosch) for the stock unit are in this doc on page 4 http://www.f650gs.crossroadz.com.au/.../GSECUInfo.pdf

What you are saying though is it stalls at idle and has flat spot about the point the BMS moves from closed loop to open loop. I would look at the idle actuator & ensure it is clean plus check the o2 sensor and wiring, problems with these are also known to give symptoms like you describe

Also check the whole lenght of the throttle cable to ensure it is running freely and not giving a false zero when starting.

Mine did when the little rubber piece on the cable between the cable sheath and the thottle housing moved on the cable and got caught on the throttle housing causing the butterfly/ air intake to stay open a couple of mm's even if the throttle was shut at the handlebar. Would run when I gave it gas, but died as soon as I let go. Easy fix, but I just stubled upon the culprit by chance though.

It's been a while since I've seen my bike, let alone taken the whole top of, but I believe this picture shows the rear of the throttle housing as it is mounted to the top rear of the engine. On top goes the rubber ring that connects the air box/ intake with the throttle body. The throttle cable comes in from the left through bracket #4. the rubber piece sits on the cable between #4 and the housing. I don't think the plastic bit where the cable attaches is actually in the drawing though and I can't find any pictures of it.

The sycl 4.6 battery drops right in with the anderson connector.
No modification needed. An extension cable 8awg of about a meter is needed to reach to the new place.
Herrhelmet is excellent seller. Fast response and willing to help me out with my enquiries.

Try this- it is a BMW injector available in the USA at NAPA stores (yes, I know you're not in the US). Part number is 13559, and hopefully it cross-references.

...

Could this have anything to do with the ecu switching between open loop / closed loop at a certain RPM? The only other thing I could think of would be an issue with the fuel pump...

[divimon2000]

The Diodes are in the green relay looking box.
CHeck chafing one more time behind the "L" bracket where the shock adjuster is
If you havent, check the fuel pump wires where they connect to the top. Notoriously short causing breakage
I wish you were closer, we could swap parts, but then again you'll have a good set of spares next time!

[divimon2000]

Oh, and the injector looks correct but check it here against your BMS software:

call me crazy but im looking to lower the dakar a little and was wondering if i used a standard f650gs shock in place of my dakar shock would that be all i need or do i need the linkage too? and how much would that lower the rear? thanks in advance.

[1911fan]

Koubalink lowering links would be a lot easier. Drop the forks an inch to match and you're done. Fast and simple. I'm doing this to Mrs1911fan's GS650 before we start riding again in the spring.

Price it out Kubiak. I agree, you should just be able to use a link and drop the front. "IF" you find you need more I have a std GS shock and forks (although I still think you could just drop yours the diff) and 19" front avail.

[LoJack]

I have a set of Kouba 1" lowering links I am using currently and want to switch back to stock but can't seem to find them (it's been two years, so likely they are gone...)

Care to trade?

I also have the 2" Kouba links that I used for a short time that I've not been able to sell, so you can have them for shipping cost.

Let me know.
