While this may not matter, putting on a sidecar voids your warranty instantly. I believe it even states that in the back of the owner's manual.
A friend of mine has ridden with sidecars for years and he swears by them. But he only puts in on when he's going on a long haul and carrying 3 people. He also changes the tires out to ones that are more flat and like car tires since there is no more leaning of the bike.
