Rode my bike into work this morning and it feels completely different to when I rode it home from work the night before.

The powerband seems to kick in a bit later (around 9krpm instead of 8krpm), it has the slightest bit of resistance just before hitting the powerband and also seems to stutter slightly when releasing the throttle (the revs don't drop smoothly or quickly like they used to).

I have no idea what has happened overnight for this to happen. Has anyone else experienced this before?
