I use Lucas Oil assembly lube. Its sticky so won't run off components while you are assembling.

"Driven", make a very good assembly lube (grease), I put it on Cams, pistons, big end and timing side journals,  anything really that's a metal to metal contact. (don't put anything on the rings, piston skirts only).

Normal engine oil will run off by the time you come to start the bike (If your not getting it back together and running in a short space of time), I've also used Morris Competition assembly oil, its like treacle and very messy - its good stuff though, the Driven stuff is tidier and doesn't drip.
