SOURCE: Drain and change 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.,

SOURCE: level of oil in front forks

not sure about newer models but the old models take 280 ml in each fork

SOURCE: KX 125 (2003) motorcycle

its 120 mm or 4.7 inches from the top of the fork
Some measure the oil quantity and fill the fork up, some fill the fork up and measure the oil level. The most correct method is to measure the level, I guess, but many guys measure in quantity.. both ways work well.

Hi Lukepentcof.

its 350cc or 11.8 ounces in the Clyma book, but that's for a 1986 onwards model. you can vary the amount you use to suit your style of riding anyways. I doubt it would be that far from the mark.
