Noise and shimmy ~ Found

Over the past several thousand miles my 919 has developed a noisy low speed vibration,1500-2500 with light load. More vibration in the bars, and I noticed that with cruise control on and low speed, I had a shimmy at 40mph.
Yesterday I decided to check my steering stem bearings.
1st thing, the chrome top lock nut should be 65lbs of torque. Nope was pushing 10-15 lbs. Further disassembly found that the lower lock nut was loose on top of the adjusting cone. The tabbed lock washer was in place, but, it was less then finger tight. I could grab the nut and washer while installed and wiggle the whole shebang.
I torqued the cone, 18 lbs and installed the washer and lock nut tight against the cone. Then re-assembled the top triple, and torqued the chrome nut to 65lbs and finished up. After about 60 miles some of it in the rain. I can say I found all three bugs.
No vibration in bars, noise in front end, or shimmy at low speed.
I didn't take the bearings out for greasing, because, I grease mine often thru a zerk fitting on the steer column.
If you're having any of the three problems I listed you may be as lucky as I was.
Rubber down and hormones left at home, make Joe an old rider.

Good catch Dickey! I better check mine too. No shimmy right now, but that coulda been disaster if it went too far.

Glad you were able to trace that down. That would have not been good if it went unnoticed. Thanks for informing the rest of us!
