this what I got just bought the bike for the wife Bike had a miss in it thur all rpms Changed out the worn out Carb with an S&S .072 main .295 inter jet ran better but still had the miss and didnt idle any better so changed out the total Igintion system back to stock, wiring harness and all the rest went to time it and couldnt get a stable timing mark due to the rough idle now checked VOS switch found it was bad replaced it now I can see the timing mark but it is still not a good idle runs real rough on idle but above 1500 rpm smooth as a new borns butt when I pull the Vac line on idle engine smooths out I guess the ? is no telling how long this bike was running with the vos switch bad did it do some damage to the top end valves are semi carboned up the new plugs are sooty black after and the engine seems to be running on the rich side there is nothing wrong with the carb or the ingnition system took all that and tried it on my other fxr ran fine did the valves burn from running with no advance for god knows how long Did a compression test shows 110 to 120 psi
