So I've bought this cbx750, been riding it about. It's a heavy thing, about 240kg wet. It has a center stand and a side stand Now, don't laugh, but.. .. I don't know how to work the center stand. I've tried pushing down on the stand with my foot and pushing back on the bike to roll it on, but all I end up doing is overbalancing. What's the trick? Also, if anybody knows how to change the oil in one of these... it's sounding a bit rough and I hear the older ones tend to consume a fair bit.
