hi buddy right start with warming the bike up then underneith engine will find the oil plug unscrew it then drop the oil out into a pan once drained put the plug back in and tighten it also it is recommended you change the oil filter every oil change as dirt in the filter will turn the oil black then you unscrew filler cap on side and fill with oil i recommend using silkolene pro 4 then fill it until the oil is 1/2-3/4 full on the sight glass thanks bud i hope this helped
