Yes it heats up the oil and lets it drain better.
Yes , if you want to , and then top up the engine oil ( but in the long run it's best to change both )
You CAN change the oil filter by itself and then top up the oil , but it's best to change both in the long run
it depends on the oil tank
It depends on how loyal you are at changing your oil. Do you change your oil every 3,000 miles? If so you can wait to do it every 40,000-50,000 miles. If you are not so good at changing your oil and you use cheap oil then they recommend every 30,000 miles. It will run you $50 to $120.
As long as there is oil in the engine it can run. If it has not had an oil change for a year even if it was stored I would change the oil/filter before driving this car.
No, but it helps. Warm oil flows out much more easily.
Start the bike up and let the oil warm up (side of the cylinder should be pretty warm to touch) before killing engine. Remove drain plug (on bottom of engine) and let all oil run out. Replace drain plug and remove filler plug on side of cases and add oil.
Did it run before?
Standard is full choke first, then half-choke for a couple of minutes, then run.
Most motorcyles have a liguid clutch which means they run in motor oil so when you change your motor oil you are changing your (gearbox) transmission oil and to check your (gearbox) transmission oil level you check the motor oil level.
the oil type should be T76 5w-30. i don't use synthetic, but if you suspect sludge buildup, go to your local advance auto parts and ask for seafoam. it's like a dry gas type liquid, but it can clear up sticky lifters and valves when added to oil. run it around the block a few times before changing the oil.
In general, the computer can tell you when a sensor has failed. Always run a computer diagnostic test before you rip into changing sensors.
