Question about BMW Motorcycles

1 Answer

Hi there, my BMW 1100 GS cuts out when the temp gauge stops working. She re-starts immediately and continues to run when no temp bars are showing. If and when they do re-appear, the bike huffs and puffs and cuts out. On re-starting she runs perfectly even when she is hot and when no temp gauge bars are showing. Any suggestions?

Hi, Peter the following applies to carbureted also fuel injected models and the usual suspects are:
1. Severely discharged or damaged battery, 9 volts or lower.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.
4. Failed main circuit breaker or ignition switch, check for loose connections and continuity.
5. Failed system and or ignition relay, check for continuity.
6. Failed ignition coil, ignition/electronic module.
7. Failed CKP, CPS, CMP, MAP, TPS, or BAS sensor, corroded, loose or broken wire connector pins/sockets.
8. Throttle cables and or idle speed improperly adjusted hot idle speed should be 950 RPM to 1000 RPM.
9. Air/fuel mixture screw improperly adjusted.

SOURCE: engine misfire and cutting out when running at normal engine temp

Make sure your fuel tank vent is not plugged. To see if this is the problem, the next time the bike starts acting up, stop and open the fuel tank. If you hear a whoosh of air being sucked in you know your vent is plugged.

The C8HA is still available, it is NGK stock number 2168.
Good luck.

SOURCE: Fault with electric start on my Suzuki GSF 250 Bandit

Check that the clutch is in, kick stand up, and neutral light ablaze. Then try your start button. When you had it running and hit the button, the starter engaged at a slower speed then the bike engine was turning, which led to the stall. The stall means your starter works. If the starter works when the engine is running then it is wiring. Check your kick stand wiring along with the clutch wires which plug in on the handlle bar or where the clutch cable enters the engine.

I have a 2001 dakar and my speedometer and rev counter runs up and down randomly plus the clock and odometer just flickers the whole time.

Hi, Patrick, whether one, some or all of your gauges act erratically, flicker, or go dark immediately after startup or a few minutes later while riding the usual suspects, are:
1. Blown instrument fuse.
2. A bad ground in the gauge circuit.
3. Faulty wiring before or after the fuse.
4. Faulty dash wiring harness connector.
4. Faulty wiring or connector between the fuse and sensor.
5. Faulty wiring or connector between the sensor and gauge.
6. Gauge sensor has failed.
7. The gauge has failed.

My problem is with my BMW 1100GS. It has 174000 kms on the clock and runs beautifully except that , when idling and when its hot the engine cuts out. It starts immediately when the stater button is pushed,...

With that mileage I would look at the wiring from the ignition switch. Start her up and have a good wiggle to see if it cuts out. This part of the loom can be replaced/repaired and it is not an uncommon problem. Peel back the outer sheaf, you may find a lot of green corrosion here and fragile wiring.
The other option would be a failing hall effect sensor (HES), but check the wiring first.

V65 magna was runing 2 bars on temp gauge and now it runs 5 bars

The V65 should run on 3 to 4 bars, When stop & go traffic it will run 5 or 6 unless you have installed a fan switch so you can turn the fan on, If it ever hit 7 shut it down but 4 should be right on the right temp, I have never seen a V65 run only 2 bars, Something was not right causing this.

After starting my 2009 BMW R1200GS the fuel guage showed over half a tank, it was warming up and then the low fuel warning light came on. The fuel guage is completely blank, no bars at all. Any thoughts on...

The fuel gauge sensor on my 2008 1200GS Adventure was defective and needed replacement. On my first ride after buying it new from the dealer it showed full (all bars), but ran out of gas on my first ride. No further problems, and it is now 40,000 miles.
Hope this helps.
