Look in my build thread for the process I used. The rear seal is a PITA but doable and mine is leak-free since the repair. There are numerous posts on doing the chain - it's not too hard as long as you're careful and don't drop the existing chain. BTW - I'm still running my old 200.000 mile chain with no issues at 5300 RPM but only a few miles/year. The chains are pretty tough. (Now that I said that out loud mine will promptly fail........)
