XS400D
I ride a 1977 XS400D I just rebuilt both carbs. I have not had them synchronized yet. sometimes it idles fine at about 1200 other times when I'm driving and come to a stop it will get stuck at 2500 or 3000 rpm and stay there despite goosing the throttle. other times it will gradually idle down so low that the bike shuts off. the carb kit came with main jets with fewer holes in them so I cleaned and used the original main jets. any body else have that problem or any suggestions?
