I put on a lot of winter miles on my 200 a few years ago. The muffler rusted out. Got a new cast-off one from an inmate here.
Also, the Kientech jet kit plus messing with the idle screw really takes away much of the cold-bloodedness of the bike.
Well, I ain't always right but I've never been wrong.
It seldom turns out the way it does in the song.
