Here’s today’s entry:
Shoutout to the LBS owner who put this eMTB chainring lockring on with an impact driver. He came to the customer’s house to do it. I guess he couldn’t be bothered packing a 45Nm wrench 
That cheat bar is half a meter long. I had to stand on it with roughly half my weight - the frame was flexing like a yoga teacher as was the wheel, and the 4-pot brakes struggled to hold the wheel still despite being strapped hard down. I was seriously worried it would permanently damage the motor/frame.
It wasn’t moving, so I poured about half a can of Shock Unlock onto it. Then it broke loose - with a gunshot crack.
I reckon it took over 200Nm to break it free. The spec is 45.
Well done Yamaha for making motors tough enough for reality. Yay bike industry 
…I’m now wondering do I need to buy a 500Nm impact wrench to have in the event this sort of stuff turns up again. @Dave_Rome what say you? Would an impact wrench be a safer bet for this sort of thing than a cheat bar?
Moral of the story? Never underestimate the cack-handed agriculturalism employed by the last edjit to touch the bike you’ve been handed.
