I have a crappy stand but it does its job. I measure the slack in the chain following youtube tutorials, channels like Motorcyclist Magazine put out some really informative content.
Anyway I usually leave about 3mm of slack and the chain in my Husqy had about 1mm of slack, so yeah pretty tight.
I took her to a shop and they loosened the chain back to 3mm, giving the wheel a few thumps to make sure that it was pulled right into the adjusters as you said.
It’s been a couple of days and she seems fine but I’ll keep a close eye on it, it’s a pretty weird thing to be happening.
