I was able to aquire a set of carbs that belong on my 76 550k. When I got it, it had PD carbs, presumably from a 77. I cleaned the carbs installed them and the bike starts up beautifully (thanks SteveK). My throttle cable on the pull side seems like the casing is the right length but the cable itself seems WAAAAY too long... any input? Thanks.
By the way, if anyone from Z1enterprises sees this, the new site is a little troublesome locating specific parts now... I suppose I could just put that to them and not on here...
