R1150GS twin spark problems

[Dave Alquist]

 A 2004 R1150GS is intermittantly difficult to start-almost like it's flooded and won't start unless I open the throttle all the way, then starts to catch and "clears it's throat" and starts. It doesn't do it every time, mostly after sitting for a while. Test for Tank Vent valve makes the bikes fuel pump run, and shows the vent valve is "off". Any ideas?

[Caspar Berends]

Have you checked the TPS setting? As far as I'm aware, the 1150 does not have a Tank Vent Valve.

I sold my r1150 rt & my gs911. From the looks of the problems with BMW motorcycles I will never own another. There are better choices out there (more reliable bikes).

Does the bike run well after starting up?

George

[Dave Alquist]

 Yes, it runs well after starting. We've found a couple other glitches since, including no free-play at throttle cables, and a very rough starter motor that draws heavily on the battery ( 6.4 volts while cranking).

 Most riders have good luck with them. I repair them for a living, and I only feel like blowing up the factory once or twice a day!

Sounds like it needs a proper tune-up, including TPS adjustment (can indeed result in lousy starting). Regarding the battery, it could also be defective.

[Dave Alquist]

 Will check, as owner has installed aftermarket cover.

 Thanks for the response, just been tuned, found a few other glitches, maybe today!

Check the throttle cable at the throttle body to ensure that it is properly seated. It is easily displaced if you have done any work that involves the tank or right side of your bike. I had this issue on my 04 GSA.

 Thanks for the reply Ron-we're still working on it.

Pleasure Dave. Anything you need just write it up. This gs911 forum seems pretty good.

Hi, this morning I did idle actuator calibration and engine synchronization
(lock idle actuator) with GS911 on a friend's 2011 R1200GS.
The idle speed went low afterward. It's running around 1000 rpm instead of
around 1100-1200rpm as it did before.
No fault indicated by GS911.
I exactly followed all the procedure told by GS911 during engine
synchronization.
Any idea?

Budi

[Dave Alquist]

 Thanks for the response Steve. That's something I'll check!

Do me a favor and contact our Help Desk too...

in the meantime, you can clear all adaptation values and relearn.. (will
have to relearn the gear position potentiometer etc... but details are
fully explained in the software (start in neutral and proceed to ride in
in each gear for 5-10 seconds minimum)

best,
Stephan

Thank you for responding. I have forward this subject to your Help Desk.
I will try to reset the adaptation value this weekend.
In anticipation of relearning the gear position potentiometer, do I expect
running the bike through each gears on centrestand or real riding?

Rgrds,
Budi

[Stephan Thiel]

hi Bundi

If the bike has a centrestand, it most certainly can be used, however
the roadbikes don't and they need to be driven...

As always - safety first - It is always good practice to ensure the
centrestand is tied to the front wheel when doing this... you don't want
your motorcycle coming off the centrestand while you're in 6th gear!

best,
Stephan

[Budi Sujanto]

Thanks again.

[Gabriel Milewski]

Hi,

I was reading your idea on running the bike on the centerstand in gear. From what I've heard, running shaft-driven bikes like the R1200GS in gear while on the centerstand might be bad for the universal joints, which may be outside their working range in that position.

I'm not saying something will break at all, but you might want to think about it.

Kind regards
//Gabriel

Hi,
I got your point and I'll add that to my consideration.
Thank you.

Just telling you what the process is that BMW suggest...

also.. doing this is far easier than riding... you try and gear up every
10 seconds... ;-) ..the bike starts jerking in 5th and 6th.. if the
speed is too low...

Alternative: - have a workshop in a hanger next to a runway ;-)

Stephan

The adaptation value reset has solved the low idle problem.
Case closed :)
