Here's another YZF newb question... With the spark plugs removed on a YZF750, just how much resistance should I expect to see when when trying to turn over the engine by the back tire when it's in six gear or have a bolt threaded into the crank?

My bike sat for about ten years. So before firing it up, I wanted to get a little oil on the top end. I pulled the plugs and removed the valve cover. A little Marvel Mystery Oil went into each spark plug hole and I liberally sprayed PB Blaster on the valve train. But it still takes quite a bit of effort to turn the back wheel. It does seem to be getting a little better but there's a lot more resistance than I would expect. Do I have an issue here or is normal?
