Anyone else experiencing this on the Rushmore models? Mines a 15, and while out on a ride Saturday, I parked the bike because I was going into a store. I had a helluva time getting the ignition to lock. The key wouldn't turn to lock it. I ended up stopping at the local dealership and the senior tech recommended some of the HD lube that comes in a pen. I bought some and it's loosened up a bit, but in my opinion, I've got to push down pretty firmly on the switch to turn the key. It's never been removed so I know that's not the problem. The only thing I can figure is that it's gotten really cruddy because I live on about 1/4 mile of gravel, and it's always dusty here. Any input on this? If it continues to be a problem, it's still under warranty, so I'll get it in do they can repair it. I'd hate for it to decide not to unlock one of these times.
