I got the cheapest timing light from sears. 15$? It's been fine and weatherproof for a few years now.
My dipstick says 2L, but I really fill to the full line. Mine has an aftermarket sump cooler on it, so the manual isn't much help.
I rode mine for a few days and discovered after the fact that the transmission didn't exactly have oil in it, just water. So, maybe drain and refill that.
