Where to get timing chain

[WelderDave]

Was doing my head and when I was setting timing I noticed that it was off despite moving forward and back a tooth, which made it worse. So after some digging online it sounds like it’s because of chain stretch that allows it to be slightly off despite the tension era best efforts. I guess I’m equivalent it looked as if it was 1/4 tooth off.
So my question is, where does someone find a new cam chain? I don’t want to pull the whole motor apart but I’d be interested to see what’s out there as google showed up almost nothing.

Search by OEM part number. Yamaha even still had them not to long ago as some 4-wheeler motors still used them. I would also look for a new cam sprocket. But that one might be harder to find.
