He's noticed a vibration in the engine when above 70mph, which makes the bike uncomfortable over long-range rides. He thinks it's coming from the bottom of the bike.
Today he put the bike on the sidestand in the garage, started to walk away and it curiously toppled over and bent the gear-lever. This resulted in him dragging me out to help him get it straightened (bearing in mind that I've got a possibly-broken wrist!), as he needs it tomorrow for the first day of his new job. In the course of doing this, I noticed that when the bike's in neutral with the clutch in, the engine is the only noise. When you let the clutch out, there's a noise like something's catching in the engine...which you can also feel throughout the bike. I feel the two symptoms may be related.
He also states that the neutral vibration/noise only happens once the engine's up to temperature - when it's just been fired up it's fine.
Any ideas?

when the clutch is engaged part of the gearbox is spinning too, hence the additional noise
i'd wager it fell off the stand because he didn't put it down fully
all engines vibrate differently at different rpm, the SV does it at ~5k, over 70mph = motorway cruising = bored = notice things you missed before
