I'm with Gregster on the danger factor in using the engine power to rotate your chain, but I'll go a step further and say that's not only dangerous but incredibly stupid.
Too many people have lost digits to chains. Engine off in neutral is the only way.
Having said that, I'll also say that on my 6mo/25k mile odyssey around the States, I carried a small can of PJ1 black label, and used quality chains/sprockets. My lubing schedule was/is sporadic, from every day in the sandy stuff to almost never.
I typically average around 15k miles on a chain on the 950.
