The carbs were spottless. I believe the first previous owner had them cleaned before I had bought it off the previous owner who said he rode the bike about 5 times in the past 9 months. I'm going to take out the carbs tomorrow and inspect them. I do remember that when I replaced the main jet on the front cylinder carb that the whole assembly came off and I had to unscrew the jet apart from the bottom of the unit and screw in the new main jet and then screw the whole unit back into the carb. That part took me aback because in the instructions the main jet is supposed to just unscrew off and then you screw in the new one on but I had to kind of just guesstimate how hard to screw the whole unit back on.
