There’s a hole in my bucket

tm100_crankcase_hole_smallI had a bit of a disappointment tonight as I was cleaning up the little Suzuki motor to ship off to the engine builder. Upon turning it upside down to clean the gunk I discovered a hole along the centerline of the engine cases. “Uh oh, this can’t be good.” It’s an odd little hole, sort of square. It’s located in a place where someone may have tried to pry the cases apart with a screw driver, but it’s not broken like that would be. There’s a bigger picture here. The bike wasn’t leaking gear oil, and it wasn’t empty because I drained several hundred CCs out of it before I pulled it from the frame. That means it must be under the crankshaft – which could explain why the engine ran so poorly, but the cylinder shows no sign of sucking dirt. It’s weird. But anytime there is a hole in the motor it means my repair bill could be significantly higher. We’ll just have to see.

    Turns out the hole in the bottom of the TM motor is supposed to be there. It’s a drain hole of some sort. Right there in the bottom of the motor. Whod’a thunk? Glad to hear that. Now it’s off to the post office.
