I have a 2017 z900. It has 28k miles on it and I got it with 19k. Not sure how old chain is (At least 9k). I overtightened it recently and now I want to loosen the axle nut and it turns but it doesn’t loosen so I can adjust the wheel. Any ideas? I’m using a breaker bar and I can get it to move but it’s not loosening. Tried everything and I can’t figure it out. I ordered a new chain and sprockets but I want to at least get the axle nut loose because I will need to remove the wheel. Seems like the right side is moving when I try to loosen the axle nut. I tried holding the right side in place but it’s hard with one person. Please help.
