Had my bike at the shop for a carb sync and drive line maintenance. Noticed that when I picked it up, the trip meter was 0. I had around 90 miles on it when I dropped it off. Figured they pulled the tank and unplugged it. No big deal. Went for a ride and meter worked, and miles stayed after shutting off and restarting. Went for a ride today, and it was back at zero. I'm going to pull the seat off and check the plug. Any other suggestions? I assume it uses the main battery for memory and not a dedicated battery.
