When I push my chain up (under the swingarm) between the front and rear sprockets, the top portion (over the swingarm) also moves. I don't have to push hard at all.

What does it mean? Is that normal? (I'd never noticed that before).

You don't suppose taking the slack out of the chain has anything to do with it?

 

[SittingDuck]

Oh, I absolutely suppose that's the case, but considering the chain is wrapped around sprockets at either end and that the sprockets don't move (tranny in gear and wheel on the ground), I was a bit surprised.
Am I right to assume you're saying it's not a cause for alarm?

If the gearbox is in neutral the front sprocket can turn when you take the slack out.

Oh really, I guess the rear can't move for some reason

Sitting Duck,

Perfectly normal and absolutely nothing to worry about.

Thanks.
I hate how noisy this chain is...
It's not due to a lack of lube; my scottoiler is pumping lots of atf onto that thing...

Sometimes ATF isn't always the best lube for a chain. It doesn't have much in the way of clinging properties and basically migrates around from metal pentatration. Oil on the other hand migrates via contact and will spread over the length of the chain better with an automatic oiler. I run Mobile 1 15W50 in my Pro-Oiler and it keeps my chain lubed very well and keeps it quiet. I'm using my next to lowest setting so I'm only filling my reservoir (6oz) every 4K miles give or take a little.
