My 2008 Honda Rebel will not go in neutral?

I have a 2008 Honda Rebel that will not go in neutral while its running. It will only go into neutral if I shut it off. I took it to the local shop and they adjusted the clutch cable and gear lever with no success.

If you believe that Shop stop believing in everything.
Okay, there's a problem and a simple clutch cable adjustment didn't fix it.

Have you change the oil and filter lately? Inspected it for debris?

Quite possible that the inner shift forks are warped/bent which means a minor rebuild.

Sorry, best that I could do without more info.

Transmission repair is necessary.

I can't rule out mechanical damage from your description.
But… If it shifts not running, that at least proves it's not totally busted.

Clutch adjustment starts at the clutch itself, not the cable. Cable adjustment should be last because it only sets the free play at the lever. Find another shop, or a manual. Those guys must be clueless.

Sure sounds like the clutch is not fully disengaging.
