1974 Honda st90 repairs

[Jimbo’s_st90]

Hello, I need help finding what drive chain size I need for my dads 1974 Honda st90 that’s been sitting in the garage for 30 or so years, driving this thing is a blast! But every time I take it out something new breaks this time I noticed a link that was about to give out but I’m having a hard time finding what size I need. Any help would be appreciated!

It’s a 428 chain ,sorry I do not know the length off hand .

Those bikes are a little tough to find parts for ,DR ATV is a good site to look through ,as they have some parts but they show the parts diagrams so you can search by part number in other places .
