so the other day I started my mc21 and when I rode off in first gear it sounded like a piece of metal what loose in the gear box.

what to do now, parts are available right?

maybe best to drain and flush the gearbox first? see if any metal parts drop out.. then refill with a good quality gear oil... when was the last time you changed it?

or maybe thats not a good idea and try to source a used gearbox or parts to rebuild it

heres an example on the price of parts, keep in mind it is in AUD.

Seems coincidental having just replaced the oil? Did you check the oil when you changed it?

i just changed mine too better double check it again.

refilled it with 700mls of gear oil... when checking the gear oil is the bike supposed to be upright?

Yes the bike should be upright when checking the oil level.

If it was fine before you changed the oil and not now, I wonder if something fell in there whilst the cap was off. Did you use fresh oil from a seled container?

(A dumb question I know, but worth asking all the same)
