Strange noise coming from the new Jogger.

Think it's clutch or gearbox related. Like a mechanical, gritty/whirring noise you can hear after changing gear. If you come to a stop, the revs drop and then this noise continues for a few seconds - like something whirring/continuing.

Clutch/pivot release bearing maybe?

Only 500 miles, and just after collection there was a burning smell and juddering from the clutch, which disappeared after 20/30 miles.
