There is no one answer for oil- personally, I use mostly 5w-40 Rotella Synthetic, mixed with a quart of Amsoil 10w-40 synthetic. I also think the Maxima brand motorcycle oils are very good. For a very old motorcycle, the 15w-40 Rotella diesel oil may cause fewer wet clutch problems, and is a high quality regular (cheap) oil.
I use a Walmart Supertech oil filter made for a car, and it fits perfectly. Some say only use the motorcycle brand of oil filter, others say the Hiflofiltro brand is the same as the dealer oil filter for a lot less cash. Generally, most hate Fram oil filters- the quality company that used to make them was bought out by a low quality company, cashing in on the previously good name.
TCLOCS stands for Tires, Controls, Lights, Oil, Chassis and Side stand, what to check before you take off.
