Man that’s bad. I cut threads at work everyday (single point , thread mills and rolled threads). I can get long winded on thread form… the importance of thread: major OD, thread flanks, pitch diameter, thread root….
If I needed to save a week/weekend of riding especially far away from home I’d to what I needed to do to save the trip. But then again I’d park it and fix it the right way by getting a new crankshaft.
Is this your only engine? Back up?
Thread file won’t work. I’ve used honing stones to “deburr” thread imperfections but what you have is beyond that.
From the looks of it you have to re cut the threads. I’m thinking the thread blank diameter is going to undersize thus causing a sloppy fit with the nut. A thread chaser won’t work.
