I had my Viking vi out for its first long run since I purchased it. There are a couple things that I notice. One being that when it shows the fuel light blinking, it only takes 6 gallons to fill it. The other is after about 35kms my nice quiet ride, started squeaking badly. I never had it in mud and the trail was dry. It squeaks so loudly that you can hear it at any speed. Anyone else have a squeaky Viking?
