Where is the dipstick on a 2005 Yamaha YZ 250?
The 2005 Yamaha YZ250 does not have a dipstick. Instead, the bike uses an oil sight window to check the oil level. The oil sight window is located on the left side of the engine, just below the clutch cover. When the bike is on its side stand and the oil is at the proper level, the oil will be visible in the sight window.
