Should I assume that standard Car Garage bulk buy stock oil is 20/50?

That oil should be fine for your bike. And I'd bet it's 10W-30 oil he gave you...... that's the most common, cheapest oil and ussually what garages use as thier basic standard.

but just like a littlle in the crankcase

I'm a huge fan of MMO, and have had great results with it in my Land Rover. But I was worried about adding it to my motorcycle's crank case because it would lower the viscosity of the oil in there and possibly creating slipage. Is this something I shouldn't be concerned about?

My motocycle has been sitting for some time and I imagine the crank case could use a little cleaning but thought that shorter intervals between oil changes may be the way to go over lowering viscocity but if the MMO works I'm all for it!

Pour some SeaFoam into your crank case (per the directions, of course) and go for a ten mile ride or so just before changing the oil. That should flush any impurities and remove any sludge without the risk of running for an extended period of time with thinned-out oil. If your bike is prone to sitting, switch over to synthetic oil.
