200cc Gio Beast Chain

[Rusty69]

Hey Guys, I'm new around here and was wondering if anyone knew the pitch of the chain on a 200cc Gio Beast. I stretched mine and don't want to replace it with a stock one from Gio. Being that there are no numbers stamped on it, it makes it hard to find anything for it.

The chain is 428. Can't recall the length, just count the links or measure.
