Today do some maintenance, then saw a 3 nut tighten cap (is it
the oil filter?) at the engine, so open out to see what is it.
Black oil starts leaking out, so immediately close back and
tighten. In the end the oil leak about 1 plate diameter on the
floor.
Question is: how to check the level of engine oil? My bike is
Virago 125, got a gauge at the engine there, but inside is clear
liquid leh, so dun is it use for engine oil or not. Also, got no
max. or min mark. Inside the filler cap also not dipstick leh.
