While you have it out, don't forget to file flat the top of the flange on the right lower engine bolt's mount. That flange can make it impossible to reinstall on some occasions! It almost always damages the "groove" across the bottom of the engine, where that long bolt goes through, on the way out.
When putting it back in: tilt up from the front slightly to start, then level out after the 1st exhaust pipe bolts are past the right frame downtube. Then go level to the next exhaust studs and tilt back up to clear them. The rest is cake.
If you did remove the oil pump and it's "crankcase" cover, protect that gasket surface on reinstallation or the frame can gouge it pretty nastily on reinstall. I always installed with the pump & pan installed, for that reason.
