96 k1100rs first ride report + humming sound

Finally got the brick to a point In which I could take her for a low speed test ride around my neighborhood. Whilst cruising at about 15mph a took notice of a humming sound coming from the final drive area, nothing profoundly loud but enough to hear if you pay close attention. It's a constant droning "Hum hum hum hum".. any of you notice this on your k bikes ? Should I be concerned? Also it should be noted this bike has 127,000 miles on it
 
Tires are 6 years old and haven't been ridden. So in the parts bin I found two wheel spacers. I of course only have one installed (on the final drive side). Would there be any reason two would be used ? (Also this bike came to me in pieces so I wasn't able to see it assembled )
 
Ok good haha. I'll re check everything in the morning. The very last thing I will check is the drive shaft. I would think if that was out of phase it would sound differently than the humming I described and vibrate like crazy. I've never INproperly installed a drive so I don't know what it would sound like. I'm very confident I have it installed and phased correctly but we all make mistakes.
 
I found the problem. It was the tire rubbing against the large zip tie I placed on my swingarm to secure the abs sensor cable. There was good clearance when the bike was on it's center stand but when I put weight on the tire it expanded just enough for the cut tip on the tie to come into contact with the labels on the tire wall.. I guess we all need to laugh at ourselves sometimes. I took her out for 20 min with no hums to be heard.

Always enjoy hearing a happy (and inexpensive) end to a story. I hope the rest of your project ends the same way.
