Yes, you can do it, read the instructions that are on the link listed on Pieman's 1st post of this thread. If you have a ceiling hoist or portable engine puller, you can rig your bike to lean over to its right side as no damage allows, and you will only lose about a cup of oil, when you pull the engine case. Don't forget to get a case replacement gasket for when you go back together too. If you have a torque wrench and a manual, you can be sure you do not over tighten the casing bolts, remember steel bolts that thread into Aluminum have a limit before they strip the threads.
