What maintenance have you done? Changed the plugs, air filter, oil, and such? I would get some sort of fuel treatment to run through the gas tank and carbs. This should clear up any partial clog in the fuel system.
First disconnect the positive battery cable.
Then extract this screw and remove the cover.
With the cover removed you will see the starter.
Next, remove the main starter cable and the small solenoid cable.
Now remove the two bolts holding the starter on. One can be clearly seen and accessed, the other is a little more difficult and can only be accessed from underneath.
There is a small locating pin that holds the motor in place. Pull the starter rearward off the locating pin and remove it.
remove plastic side cover. Disconnect starter/battery cable. Remove the two screws holding the starter motor in place. Pull starter motor back and towards you
Do you know exactly where the oil is coming from? Remember the bike has an oil cooler at the front, could you have disturbed a connection and its running down the pipe?
The GS1150 is a real pain to get the precise oil level, and you may have just over filled it. As you are sitting on the bike, on the right hand side below the airbox (near the rear shouck adjuster), is a little plug. Just twist it to undo it and see if any oil comes out here.
My method to check the oil level on flat ground: After a run park the bike on its side stand for 10 mins. Place on the centre stand, wait anoth 5-10 mins, then check the oil level in the sight glass.
irst do a compreshion test on all the pots to see if there is any velve problems like one is leaking as slow engine speed's then change the plugs for a new set, always a good thing to do first? then tune the carbs,, if one is off a little it will miss fire at low revs
good hunting,,,mike.t
Its not difficult at all. It is a matter of removing parts and remembering where they go when its time to re-assemble the bike and follow the manual.
What is difficult is the rear seals that you should also change. They need to be plased in perfectly and with the correct BMW tool or your engine will develop crankcase pressures way beyond limits and blow seals.
Allow yourself two full days if you don't usually swing spanners and around a day if you do.
Don't forget to chock the front wheel from forward movement and use only quality tools.
