Found my way here searching for info on Suzuki M50's. I just got one - an urban barn find, a 2009 with 250 miles on it. It's not running yet. I have replaced the fuel pump and screen. The injectors are out of the bike for cleaning. I've got my fingers crossed that I won't have to do more to get it un-gunked from the years of sitting. I'll be leaning on the forum for advice when I hit snags.
