What things have gone wrong with the motorcycle?
I should mention that I bought two, brand new, out of the box, XL883s at the same time. One for me, one for my wife.
OK, well at 750 miles it left me stranded on the side of the road, at night, in the dark. As it turned out the ignition module fried and I had to call my wife to bring the truck. Due to my unfortunate circumstances, I had to buy the module from a non-harley repair shop and install it myself. Such is life I guess.
At about 2000 miles my bike developed an oil leak from somewhere under the engine. It wasn't much of a leak, but enough to leave little tracks in the garage floor. I never got that fixed.
The screws that held the side cover that covers the electronics opposite of the battery, all decided to fall out one by one. This happened on both of our bikes. I had to end up using some RTV sealant on the threads after a couple of sets of screws were MIA.
On my wife's bike, the valve cover gaskets all of a sudden began to leak like nobody's business after about two years. Instead of taking the bike to the dealership, I just bought some gaskets myself and replaced everything from that point up. It was an easy job and saved me the downtime.
