Pre-stretched! this checks out. chain link count is good.It's possible, but I'd think an extra link would make a huge difference, to the point of it going out of adjustment range very quickly. Another possibility is that the chain the mechanic installed was pre-stretched. I kinda doubt the chain was an incorrect length if you were able to keep it in adjustment for most of that 30k
I like this, and will go this route - thank you!If you analyze most reviews, the negatives are almost all related to breaking the chain. If you cut the chain, no need to break it. Generally I'll grind the pins off and pop the side plate off with a screwdriver.
With that, the only thing you need a tool for is to flare the pin. That Motion Pro tool is basically a c clamp with some sort of adapter to flare the pin. Not much can go wrong with that.
