Going south on Highway 17 along the coast, I began hearing popping noises from my rear end. I've had rear wheel bearings fail on me twice before so I suspected it was another bearing.
By some miracle, I came upon a Honda - Aprilia - Moto Guzzi shop in Namsos, Norway who had some bearings in stock. I had them installed and never heard the popping noises again.
I now have 52,500 kilometers on the Tenni. The only problem being I'm on my 4th set of rear wheel bearings.
On a more positive note, my transmission spring hasn't failed....yet
