I came back from riding last week, was looking over my bike and wiping things down prior to putting the cover back on her. I noticed that the shift linkage rear bolt was sticking out. I checked it out, it vibrated out from the shift lever that goes into the engine housing. I was about to lose it and lose the ability to shift at all. All HD Street 750 and 500 owners please check yours and make sure that your shift linkage isn't loose.
