So I recently needed to replace the tube in the back tire on my GS 450.

Now I'm getting a low whir sound when moving, even if I kill the engine and coast. As far as I can tell it is coming from directly under me. I'm thinking that it's likely just the chain being a bit too tight, but is there anything else I should look for?

I'm also needing to press the clutch a bit harder when starting to avoid lurching forward, if it is related.
