Hey guys I'm at my wits end trying to make my beautiful 96 road King safe to ride. Ever since i got it last year it has had this horrendous rear wobble on the highway. Anything over 40 mph and it feels like someone is pulling the rear of the motorcycle left and right it's really scary to ride , I have tried everything , new tires , new swing arm bushings , new wheel bearings , better shocks , touring brace from progressive , the bike rides like absolute crap and I can't figure out why , does anyone have any input

 

you did not give enough info for a real answer just a guess - did you have a oem Parts and service book when you did the work

miles on the bike - its an x police unit - it was salvage when i got it kind of thing -

mine would be --- you have a seizing in one of the fork bearings - that will make the front fork sway the rear wheel back and forth - i am not on it so i do not know if the forks feel snug or loose, or if its been off and made too tight when re assembled

 

Bike is otherwise in pristine condition not a police unit or a salvage unit

The wobble def seems to be in the rear , the forks where off to change springs but the wobble was their before nothing in front end was seized or over tightened

 

22k on it btw

 

Long shot but have you checked engine alignment and motor mount?

 

No I haven't , how does one go about doing that

 

I forgot to mention that when on the highway if I apply a handful of throttle he wobble diminishes significantly then as I back off throttle to hold speed or cruise it starts wobbling like mad

 

More wild guesses...... Alignment? Condition of motor mounts?

 

the early - late evo swing arms were and still are an issue with cracking --BUT you have been in to it soo - are you sure its not cracked did you specifically look for swingarm cracks - i have been fooled but knowing better i found that it was

the side swingarm cushions were replaced ???????? and the main front bushings ????? in the swingarm

 

Post a vid and some pictures. Impossible for people to tell with "It just wobbles and I don't know why".


Last time I heard of this problem, someone forgot to put the rear wheel retainers on the bike.
