Hi, this is my first post so I'll start with a hello to everyone
I have an '09 R1200GS, K25 0303, standard edition bike with 64k on the clocks; cast wheels and rather tatty. About two months ago the bike suddenly stopped and refused to start giving an awful squeaking when trying to turn over. It turned out the alternator had completely seized; the casing was cracked, it was rusty and furred up, the stator showed signs of uneven wear. I sourced a new alternator from France (cheaper than the UK) and went about fitting it. I found numerous posts on how to do this along with the Haynes manual, so out with the old and in with the new.
Parts replaced:
1. alternator, incl. belt, with a shiny new one, same model.
2. Upper throttle cable had a small kink so has also been changed. Routing has been checked and appears correct; as are the lower two.
3. FPC replaced
4. Service - oil, oil & air filters, spark plugs
Everything was fine until the alternator seized, now I have new issues:
5. Initially high, now irregular & low idle.
5a. Removed & cleaned TPS; tested with multi-meter. Appears ok. Reset actuators with GS-911 too
6. Battery appears to have drained despite being new. Cables & connections have been checked and appear correct.
The idle is now quite irregular, and ends up stalling after a while; it recently started with around 2k rpm which then gradually decreased as the bike warmed up until it stalled. Failed to start again without opening the throttle a little.
It seems as though the system can't stabilise itself after the parts were changed or I appear to have missed something after completing the jobs.
Do I need to carry out an adaptations reset with the GS911? On that note, I do have a replacement tps on the way though I'm not sure if this is required.
Also, I've not yet carried out a throttle body synchronisation as I can't get a constant idle. Nor have the O2 sensors been checked or the valve clearances checked.
I am aware of various posts on individual points mentioned but I can't seem to pinpoint any issues/solutions to satisfy the problems.
Many thanks
