Lower Bearing?

[weekendwarrior]

I was riding and she just died. Like it ran out of gas except no putter before. She had plenty of gas. still getting a spark. turns over fine, but won't start. Took it to the shop they said I have a bad lower bearing. But to me if the bearing is out she wouldn't turn over at all. Is it possible that is just bad enough to not start and still turn over? I checked spark, checked my coil. can't seam to figure it out. Started to tear apart my emgine to look at the bearing, and found some shavings in my oil filter. If it is there bearing please explain to me how it is possible. And which bearing is the lower bearing? Are they talking about the rod bearing or something else?

I think I would have spent more time checking the fuel system before I tore the engine apart. A "lower" bearing just seems like a general term they may be using to refer to the bottom end of the engine. The guys at the shop might have heard a knock in the engine when you tried to start it. However, a bad bearing in the bottom of the engine shouldn't cause the engine to stop, unless there is other collateral damage that may have killed the compression.

When I pulled the spark plug to check for shock, it sounded like I had good comprtion, and the smell of fuel was present.

How was your spark? Nice strong blue color? Did you hear any noises as the motor was turning, such as grinding or clunking?

Spark was strong. There is some clunking when the engine was turned over. Found metal shavings in my oil filter. I keep reading through the steps in my repair manual on splitting my case, do you really need all of the speacial tools it calls for?
