Just turned over 35K and decided to replace the OEM throttle and choke cables thinking long enough for the originals and why take a chance. Adjusted valves, air filter clean, timing set, new plugs, wires tested this year while the carb floats and diaphrams were replaced last year. Bike was running fine prior to my cable replacement Now the idle when fully warm will be fine for a short time 1-2min, then get rough for 20 secs or so, then smooth out and continue in this pattern. It is especially rough if after a spirited ride on freeway and then exit--get to bottom of ramp and while stopped at idle, shakes horribly. I have replaced the idle and mixture o rings, cleaned these parts 3 times and their seats along w/compressed air and did a carb sync with TwinMax. Starts right up, has great power and smoothness, just cannot get the idle to stay consistent. Any thoughts? Hate to replace the idle mixture, spring, idle jets and O rings if not needed. Thanks for any help my way. Jim
