Fellow AK550 Owners Question - Noticeable vibration at deceleration

[jermwars]

ITS GONE!!!!

After 6500 (ish) miles the "thump" is completely gone. I cant feel it or make it happen under any circumstances.

The guy at KymCo service was right.

I officially take back some of the crap i talked about them.

Great news!  Mirrors my experience with the X-T300 when new.  The transmission roughness under load smoothed out at about 1,000 miles.

After only 1400  reads the problem with the new 550 healed itself!
Thank goodness

We never did hear a word back from the guy that started this thread, did we...

 

Didn't realize my had so many responses and I wasn't alone (or crazy).  I had to take break, but starting riding again. Still feel the clunk, but seems to be less intense. Early February will be 1 year since I picked it up.

How many miles have you racked up on it?

I have tried to note if mine every did that vibration or shudder or clunk at deceleration. I cannot say that I have ever really felt it. I do feel when the clutch lets go but I really can't say that it was a clunk or vibration when that happens, just a release of engine drag. I now have 1339 miles on mine. So I guess if it was going to do it I'm past the time to notice.

I feel ridiculous now for having obsessed so much over it. Just glad I didn't waste the effort of tearing it down since it was never broken.

Self healing vehicles, it's a thing!  Readers' Digest version, driving down to Devon last week we were irritated by a strange vibration from the wife's Range Rover.  Eventually located it to the top of the windscreen (windshield) seal which had lifted about 10mm and was vibrating in the wind at about 70 mph. 

Decided to fix it myself with a tube of silicone sealant which I ordered from Amazon.  This arrived yesterday and so I mooched out to effect the repair.  To my surprise I discover the seal is now lying flat and no amount of gentle "encouragement" prising with the blade of a knife would persuade it to unseat itself again!  After a few attempts I decided that brute force would only make things worse, so I've put the sealant (which fortunately remained unopened) on the shelf in the garage just in case it lifts again.

Life occasionally throws up these mysteries!

Ive noticed I do feel it EVER SO slightly under just the right circumstances...when its cold, just the right acceleration/deceleration and its absolutely not something anyone would notice unless they tried really hard like i have been.

Im just so grateful that it didnt end up being degenerative. Never would have imagined it being regenerative

I had a feeling this might work itself out and i was getting my panties all twisted up over nothing once i saw this guy had the exact same issue. Suddenly it was no longer an anomaly...prior to that i was convincing myself that the dealer was jerking me around.

Thank god for the internet.

I'm glad that it worked itself out for you.
