Hi,

I'm currently in need of a starter motor and battery for a 2006 F650GS. I don't mind used and wondered if anyone has an F650GS in storage from which I could take them (and pay new price for them) or if anyone is coming to UB in the next week who could bring them with them if I had the parts shipped to them in advance?

Alternatively if anyone knows anyone who may help. I.e. Any tour companies that use F650GS' or anyone who may have a dead f650gs/one for sale in the area etc.

Any help appreciated. This is one of many major problems recently and I would really appreciate the help!

Mike

You don't need an original battery. Any 12V battery that will physically fit, will do.

Can't you find someone out there that can repair a starter motor? Its normally a pretty simple motor and in asia they can repair almost anything.

I'm past looking for an original battery and haven't had an original battery since I bought the bike. Finding a 12v battery that fits is proving difficult. As for the starter motor, we've stripped it down and found nothing obvious that's wrong; making it almost impossible to repair because it seems the problem lies in the sealed part of the motor. I'm looking for a permanent solution, not a bodge job. Having replaced the battery with a cheap chinese battery in Bishkek (all I could get), it only lasted 2000 miles. I need a more permanent solution now, otherwise I'll just face the same problems throughout Russia.

Have you tested the starter motor BYPASSING the starter relay circuit ??

A starter motor is a simple device really. Very common and easy to rebuild. But I understand your situation. Sometimes replacing is just easier and less stress in a foreign land.

To get a replacement starter motor, you pretty much just need to find a motor with the same throat size and same splines..

Yes we've tested by bypassing relay. It looks in good condition when you open it up despite a chip on a magnet. But it's dead. As I've said, I'm not looking for a bodge job. I need to be confident that this bike can get me home from UB via 7000 miles of Russia etc. So not looking for a 'quick fix', I'm looking for a solution.

Same thing happened to my Hilux it was the rectifier that went followed by the starter

Mike i would try a quick fix bodge job for now to get yourself to a Russian city (find a motorbike club ) and then get the bike fixed right there. I have never been to Monoglia but would think in Russia it would be alot easier to fix it right there rather than in Mongolia....maybe i am wrong

sorry to hear your bad luck AGAIN, good luck

P.S tell your mother the crunchie bar and other food bars she posted for me to give you tasted nice

An update on this one. I couldn't get a battery in UB and I'll be honest, I didn't come across any locals who were particularly keen to help, including the mechanic at Oasis and Vait at Steppenfuchs. The starter motor just started working again so it may have just been the spilt battery acid that initially stopped it working. Following your advice, I did what it took to get out of Mongolia and bought 2 small batteries, strapped and wired them together, mounted them on the rear of the bike and connected them using 2m cables (pictures below).

I then rode to Ulan Ude where I stayed with Sasha's family. He thinks the regulator/rectifier is broken but we couldn't get a regulator or battery in UU so rode onto Irkutsk.

Here I went to the bike shop and they didn't have any fitting batteries either. While there the mechanic tested the regulator, alternator and charging system as a whole and thinks there's no problem. He also thinks that my current 2 battery (12V 9A each) isn't causing any additional damage.

I've now decided to put me and bike on train to Moscow and ride home from there saving me and the bike 5000km. I'll be in Moscow on 01/07/14 and I'm planning to ride back to UK via St Petersburg with current set up but carry a spare battery with me in case these ones stop working.

So, does anyone know where I can buy a good battery that fits in Moscow? And, what does anyone think of the conflicting diagnosis' and whether I can expect any more problems between Moscow and UK with current set up?

When i read text i saw so many repair attemps and thinking by repair people that i doubt many of them capability and understanding of what they are fixing.

As many have requested please get your bike running and measure what is voltage output bike is giving to battery with multimeter (voltage meter)? If reading is something between 14.2-14.5V then your bike rectifier is ok. if it is over 14.5 V or more likely over 15V then it is bad and your bike is burning your battery.


Paraller connection what you have done to your battery might be enough to hold overvoltage some time as you incread A/H to 18 amps and basicly you have two normal batteries there now(how much is normal in GS650? 9 Amps?) but it will fail eventually.

Try to print out or get this fault finding diagram, get multimeter and start to follow instructions and you should find reason quite soon.

We can talk about it if you are still in need?

Please contact me.

I really like your work Mike i really do, that's how i would roll

The voltage reading is around 14.4V. I think heat probably killed the previous battery due to the stupid placement next to the oil tank and air box. Both of which get pretty hot on a warm day and there's little cooling to the battery. Using a tank bag doesn't help. Hopefully that's all it is. As you can tell I know little about electrics but that flow chart is really good and I'm pretty sure that was all done yesterday

Now as i remember I know at least two separate cases happened to friends to pretty much same bike/model range where bike batteries have died in Mongolia.

In first case it was not sure what was liquid level of battery when bike left from Finland but some distance after Irkuts coming back from Mongolia battery was dead dry and dead.

In other case battery died near Gobi desert.

I am not expert with BMW and GS650 bikes but definately for me sounds like it would be good to periodically check liquid level if you dont have AMG or gel-type battery.

First battery that died in Kyrgyzstan was gel type. Second battery was cheap Chinese acid battery but the liquid levels were fine when it died and had only done 5000km. It was extremely hot though

Ha thanks Wesley! Hopefully it'll get me back to England from Moscow!
