YARRR SUBY MONSTER!!
I was riding along on my motor bicycle, and suddenly I hear a weird sound going up hills or accelerating. Weird, WTF is that? Upon further investigation I see the head gasket seeping, and when I hit the throttle could feel a bit of smoke coming out of the gasket... yay. I got about 3 more careful miles out of it before it completely blew.
Fortunately it is a $2.50 part, and I can replace it in 2 minutes with a 10mm socket
