So,
the main issue is fork oil leakage

it’s a mess~
For vehicles without a manual, the manufacturer’s service can tell you what to do.
I called Suzuki Motorcycles and they gave me the information

well, I’ve already confirmed it’s not bent

pretty uniform★as you’d expect
Once in a while you get a bad inner that was chromed afterward, so watch out for that.
I also installed the muffler bracket, so we’re done after a test ride.
