R1100S Engine won't spin over

Hi All
Before my last post about cutting out, the bike would only just turn over , I did test the battery with a Sealey tester and it indicated it was ok,( 18 month old Yuasa). Anyway I bought a new one, after checking the starter and earth terminals, all ok.
Installed the new gel battery and the same thing happened.
I removed 2 spark plugs and still the same .
As it was on the ramp and paddock stand I put the bike in top gear and turned the rear wheel by hand ,all ok .
Pushed the starter button and it span over fast. So I put the plugs back in and it started fine. And has done so since.
Was it a stuck starter motor?
Bike is a 2002 R1100S with only 9000 miles and mint so not all gammed up with road dirt old grime.
Any Ideas ?

I reckon that is a possibility. Check terminal connections on starter motor. If the starter is temperamental it will do the same again.

starter motors can be repaired.

Hi Thanks for your reply
I did check the terminals on the starter motor and main negative terminal on the gearbox before buying a new battery. Hopefully it was a one off .

After seeing a post about a starter motor loosing a magnet , I'm going to pull mine just to check, So fairing off again to disconnect the battery :(
It might be the culprit of slow turning over and the total loss of movement.

Well, I bought a refurbished starter motor from Motoworks, fitted it and now the engine spins over faster than it has ever done. :D Job done
