Well, I have a used 2013 engine in my garage still. It has two broken teeth in one of the tranny gears. I was tempted to buy that part and do a rebuild but I do not have 10+ hours of free time to commit too. That is what prompted me to buy another member's bike here, transfer some of my farkles, and sold the rest... well most stuff.
What happened was that I was on the freeway at 80mph and somehow got to neutral and revved real high. I just tapped on the shifter, and it slammed back into gear, but heard the broken tooth rattling around. I eventually got off the freeway but could not get into third gear. It eventually stuck and I towed it the last mile home. It turned on, but I could not shift the gears at all. Opening the bottom is where I discovered the broken teeth on the pan.
I have not considered trying to ship out of country. Perhaps you know a few tricks. I just wanted to let you know I have one. I think the tranny gears is $300 or so. That engine has 150K miles on it.
