1st let me apoligize for this being so long winded.
specs: 1995 HD springer softail badboy, basicly stock, w/ vance & hines pipes, and carlinni T bars
symptoms: high frequincey vibration on decelleration, can also produce symtoms at rest in neutral by holding @ 1500-2000 rpm
backstory: a friend brought me the bike to rebuild the front end due to a bit of squeeking and age. Totally rebuilt the whole front end with all new parts and followed all instructions in the manual EXACTLY. new parts included rocker bushing set, complete spring set and neck bearings and races. when I got the front wheel out and finished replaceing the rocker bushings, I noticed that the front end stayed in the center position, and felt like there was an actual "detent" much like the detent you feel as you put the bike in neutral between first and second gear. having never heard of or seen this situation before the decision was made to replace the neck bearings, races and springset as well, "just in case" we were already thatdeep into it , so why not, right.
End result: no more squeeking, nice tight front end, smooth operation, Except!...... there is now a high frequency vibration upon decelleration, which can also be reproduced as mentioned earlier. The vibe is not violent and does not seem to effect the handling of the bike , but is a bit unsettleing, and worst of all it WAS NOT there before the rebuild. I have taken this thing apart three times now double checking my work against the service manual specs, fall away test and e very other thing I can think of.... anyone else ever seen or heard of this??????
