Hello all,
I'm new to the site but not to my Road King. I've had her since 2003 and put 65,000 miles on her.
I do all my own maintenance and am a retired Aircraft Mechanic of 30 years. I replaced the heads & re-ringed her last summer along with replacing the cam chain tensioner shoes for the second time.
Rode out to Sturgis and back again last summer for the 75th after the new shoes & top end job...everything went flawlessly.
Put her away pretty much all winter and got her out the other day went for a ride and felt a new vibe I've never noticed before.
Along with new vibe is a grating, rattling noise which in my mechanical mind sounds like a bearing rattling and crunching.
It happens at a light almost floating 1/8th throttle load....3rd gear, 4th gear, 5th...doesn't matter.
If I put heavier throttle to it the vibe settles and the noise goes away.
Roll off the throttle, floating along and vibe returns with associated grating rattling noise.
Its very, very hard to keep the noise/vibe steady as it rolls in and out of it every time the throttle or load on drive train changes.
I've pulled outer primary off, inspected compensator & checked torque, re-adjusted primary chain, re-checked belt tension, etc... no change.
Right now I took outer and inner primary off, took compensator, chain & clutch off.
Was hoping I'd find a smoking gun somewhere but thus far I haven't.
Stator magnets are all good, no scrapes, inner primary bearing isn't galled...it is slightly worn looking on inner race meaning not shiny chrome surface anymore. Bearings aren't pitted looking.
I will say, I've had an oil leak for many thousands of miles that I believe to have been coming from the inner primary bearing seal...always leaves a wet spot after a long rides about the size of a quarter or a little bigger but stops. Only outside of pulley and belt has wetness at any given time.
The bike always shifts flawlessly.
It seems I used to remember hearing a little clutch noise when idling in neutral that would stop or at least lessen when pulling clutch lever in....I don't seem to be hearing that anymore though?
I am truly puzzled but obviously very concerned as well...I cant just take the ride it and see what breaks approach, its not in my DNA make up to do so after 30 years of working on aircraft!!
When this vibration & noise occurs I can feel the crunching noise in my floorboards.
This bike has never, ever done anything like this before...we have many, many happy and flawless miles together and I've got to get her feeling better soon!
I noticed another thread on here that sort of describes the same symptoms so I've attached the thread here:

Thank you for any and all advice and please feel free to hit me up for any questions you can think of.
