New chain, stiff link problem

[Jamieg285]

I've just put a new DID chain on, but the soft link is stiff. It's my second go at it, as the first one was also stiff, but I thought it was my fault, going heavy handed with the riveting tool. I know this isn't the case the second time round, as I was extra careful.

The link was stiff right from when the inner pins were pushed through, before the outer plate was put on.

I was hoping that plenty of wriggling and a decent amount of lube (scottoiler run on prime for 10 minutes) would resolve it, but it doesn't seem to be the case.

I've not ridden it yet, and am looking for ideas on what to do about it.
