Drain and change oil


How do i drain and change the oil in derbi senda after waters mixed with the oil?

I can't tell you all the particulars from the limited amount of pictures of your bike. -Remove the oil drain bolt on the bottom of the crankcase (the universal bolt size for bikes use a 17mm wrench). -Drain the oil (remember to recycle). -Re-install the drain bolt with a new sealing washer if necessary. -The oil fill cap should be some where on the top of the crankcase. About 1 or 25mm in diameter with a raised tab for turning. -Fill with recommended oil. -There are 2 ways to check oil level on dirt bikes: 1) Oil level check bolt. On the right side cover. 2) Oil level site glass. A 1 round piece of glass on the side of the crankcase. Usually by the kick start & R brake lever. -Always check the oil level with the bike upright (as if you were sitting on it). -Check bolt - fill with oil slowly until oil comes out of the check bolt and re-install it. -Sight glass - fill with oil to cover 3/4 of the sight glass. -Remember to hold the bike upright when adding oil.,
