In a situation like this, what is the likely hood of internals being messed up? I had the same thing happen but without dumping of the clutch and I was planning on rebuilding it but I’d rather not spend the $300 on a kit when it won’t fix it. Which means I’ll buy one from Marlin.
Pull it apart, then you inspect.
If you believe it's fixable, replace bearings and synchros and broken/worn out parts.
I touched up a few teeth and the shift forks.
And clean, clean, clean......
