If you look at the right side of the motor, you will see 3 Allen bolts about 2" away from each other in a triagle pattern. Take those off. Be carefull when you pull the triangular plate cap off, there is a spring inside....don't loose it. that's all there is the filter.
By the way, the make lifetime filters, they are made all of metal mesh and you only have to wash themin your dishwasher with every oil chage.

I ride a Suzuki M50 BLVD and their is no oil reset button. I do not know about the Suzuki C50 BLVD.
According to my 2005 Suzuki C50's Owner's Manual, you need to use a 10W40 oil with an API rating of SF or SG. For an oil AND filter change, you need 3.6qts (3400mL). For just an oil change, you'll need 3.2qts (3000mL).
Obviously, like other motorcycles Suzuki requires maintenance as well, change oil filter as well on every engine oil change.
No you only change the filter when you change the oil.
3 litres if you're not changing the filter , 3.5 litres if you are
Take 3 quarts with filter change
