Removing Engine from the frame

Am about to dive head first into the innards of my GS and was wondering if anyone had any recommended methods to "slide" the engine out of the frame for servicing. I do not have a centerstand....so the best I've got to stand the frame up for such a maneuver is to prop a few wood blocks under the sidestand.

Aside from that I guess I could fasten some rolling casters to the underside of a very thick and wide wood plank.

By the by...how much does an '82 750E engine weigh on its own?
 
I know based on the SEARCHES I did before that some folks will lay the frame down on it's right side and pick up leaving the engine on some kind of a roller or jack or something.
 
It's much lighter and more maneuverable if you take the top end off first.
 
Undo all your engine mounting bolts .
The engine mounts should come off the right side of the frame .
Get a matress or some blankets and lay them on the ground and tip the bike over onto them (right hand side down) .
Lift the frame off the engine .
Have a beer .

Cheers , Simon . :)
 
i just did it like a month ago 82 750E i'd say its around 150-200 pound range, me and my brother were able to pull it out but do not try to do it by yourself it feel heavier than it actually is and there isnt many places to grab it by. Like other said lay it on the right side it will be a ton easier.
 
I think laying it down is OK for a frame, not sure about a complete, road ready bike though. :confused:
Shoot Matchless a PM, he took his 1000G motor in and out using some planks to slide it on and a little jack on wheels, as I recall.
Me? I just unbolt and then suck in a deep breath and lift it out.(not good for the back :()
Yes, it only comes out to the right, and yes easier if you pull the head first, if not, remove the little breather cover on top of the valve cover, otherwise it won't clear.
Don't forget to unplug the stator wires, they are hidden under the motor, easy to overlook and rip out.
 
I now use the trolley jack method. Place a bit of wood on top of your jack and under the sump. Lift the motor slightly (oh, and breather cover off - you need as musch room as you can get). Once you've got the motor balanced on the sump (and these motors will balance nicely - not like bloody Hondas!) pull the jack to the right of the bike. Once your jack touches the frame you have to stop of course but now get a block of wood the same height as the lower frame (you want a block approx 18 x 18 x 18 inches but you'll have to measure) and tip the motor on to the block. If you've got the block placed on top of an old formica worktop you can then really easily slide the motor away from the frame.

I use this method all the time for motor in and out of frame. I used to take the deep breath and go for it route but a slipped disc ended that. This method is much more controlled for putting the motor back in to a nicely painted frame without scratching as well.
