Yes it can;if the heads are removed first,then the cylinders. it is easier if you can get the bike up about waist high. but I did it on the garage floor for years. I have a '76 apart right now in fact. have some clean lint free rags handy. as you lift the cylinder up but before you get it off the piston,stuff sthe rags around the rod. it will keep crap out of the case and keep the rod from dropping and breaking the piston.take the old cylinders to a machine shop to see how much they need to be bored,have them redo the heads too.the cylinders should be bored to fit the new ,oversize pistons.use a shop manual for sizes and torque values take digital pictures before you start ,and as you work so you know where everything goes later.Iron heads are simple just take your time.don't force anything assembly lube is a must, if you can't find any use 2 stroke motor oil on pistons and rings during reassembly it will burn off at start up. break the rings in easy.use new piston pin keepers(wrist pin lock rings). the direction the pistons face is in the manual also. check ring gap and make sure they are staggered. if you can't locate a piston ring compressor use a couple of large hose clamps and sheet metal just short of going around the piston to compress them. you could use your fingers and install it carefully,but if you twist them just a little they will break. check out 'the xl forum' for more tricks. good luck.

Yes, once the heads are off, you have plenty of room.

Yes. If you're just doing the upper end it's convenient. Pick up a shop manual and take your time. Remember to replace all gaskets and exhaust donuts.

it can be done but is a pain. working overhead is ok but working underneath is the hard part as well as getting all the bearing sleeves placed properly. it would be best to pull the engine (motors are electric, at least in the US) and do the work. the result that it will be rebuilt properly are 10 times greater. this goes to all rebuilds of an engine.
good luck.

dont pull the motor on any sportster unless your doing lower end work (and I dont mean cams) just pull the heads then the cylinders its that easy just make sure you have a manual and keep the manifold squared off so that the manifold seals properly when you torque down the heads.....big time problems on iron head and shovel (and earlier) top end jobs.
