2. An oil filter wrench, if you're changing the filter. Either a 3/8" drive ratchet or a 17mm wrench to turn the oil filter
3. Oil--you need about 3 quarts of 10W/40. I use synthetic motorcycle oil
, MOTUL, but any good oil will probably be fine as long as you change it. Oil filter, if it's being changed--Suzuki pn# 16510-34E00. As a minor note, the sv650(s) needs 2.9Q of oil if you also change the filter, rather than merely changing the oil without changing the
4. Newspaper, something to catch oil in and a rag.
Drain the oil from a warm engine by removing the 14 mm nut on the bottom of the engine on the left side, having first spread newspaper under the bike
and put your catch pan underneath
. Remember that bolts mostly come out counterclockwise (Righty tighty, Lefty loosey). For directionally challenged, you might have to lay on your back to figure this out. Also remove the filler plug on the right side of the engine to help drainage. If you don't know which is the filler plug, check your owner's manual to find out--under oil.
If you're changing the filter, remove it using your special tool.
To replace the oil, screw in the drain plug. It should be pretty tight, but don't put all your weight on it. Replace the filter by putting some oil on the gasket, and then turning the filter on till you feel the gasket contact the engine. Using the special tool, tighten it two turns more.
Pour oil into the filler, 2.4 US qt, 2.0 imp qt, or 2.3 liters. Start the bike and run it a few minutes. Turn it off and holding the bike level, check the oil level in the sight glass on the right side of the engine. If it's above full, drain a bit out, if below low, add a bit more.
Pour the oil into a jug and take it to a recycling center or gas station for disposal, don't just pour it out. Throw away the newspapers, go wash your hands, and go for a ride!
