I recently bought a 2005 R1200GS with 26,000 miles on the clock from a guy I know and trust.
The story that came with the bike was that it was last ridden a few years ago (turns out to be four years) and has been started from time to time, but not recently.
It has been stored outside under a cover for the last couple of years and when I got it the battery was dead.
New Motobatt MBYZ16HD was purchased from Motor Works along with all the consumables to perform a full service... which I am happy to do myself as a pretty competent amateur mechanic.
With the battery fitted I turned on the ignition, let the checklist run through and pressed the started switch. All I got was two clicks from the starter solenoid.
There then followed a lot of checking, cleaning, disassembling and reassembling of various bits of the bike, following other threads on both this and other BMW forums.
Still no progress.
Since then I have done the following.
Cleaned all positive connections and checked continuity with a meter.
Installed a brand new starter.
Removed the tank, found and thoroughly cleaned both the negative grounding point on the engine and the alternator output. The negative lead was also checked for continuity, which was fine.
Turned the engine over on the front crank to make sure 1) the engine is not seized, (2) the alternator rotates. I also put the bike in gear and could get rotation of the rear wheel by turning the engine by hand (plugs out).
In a final attempt to get the bike to start / turn over. I fully charged the battery and fully charged a spare car battery.
On just the bike battery, all I get it the solenoid clicking in. With the plugs all out and the car battery hooked up, I just about go the bike to turn over a couple of revs. I installed a new set of plugs, re attached all the coils, hooked the bike up to my SUV, ran the engine with my wife giving the car some revs and still the best I can get is a few occasional rotations from the engine.
I hear the fuel pump prime, so I know that's working, but I am at a complete loss as to what is sucking up all the power that should be turning the engine over.
Any advice would be more than welcome.
