My friend Colby bought a barely-running EX250 to tinker with, and ultimately turn into a bike for care-free track days. Since I have absolutely nothing else to do right now, I invited him over to spin some wrenches. Spin them we did. For many hours. In vain.

Long story short, something screwy was going on with the spark plugs. They’d been changed already, but apparently they needed to be changed again. A new set I picked up today, fired the bike right up. The noises coming out of the engine are not supposed to come out of an engine, unless you just put a round of .50BMG through it.

Looks to me like Bumblebee needs a new engine.
