top end job

try searching your topic. I think this topic was hottly debated in another thread.

It's best to hone the cylinder. It will take all of the unburned oil and other varnish off the cylinder and help the rings seat. I generally hone the cylinder when I rebuild the top end.

On the other hand I've also done top ends where I was either to busy or lazy to properly wash the cylinder after honing so I didn't hone it. The bikes always ran fine and I didn't notice any power difference or excess blowby when the engine was torn down at the next top end.
