Any ideas on why a 05 Yamaha speedo whould quit working? Sometimes, it will register between 3-7 mph when I'm going around 35-40, and sometimes when I go really slow, it will register 35-45 mph. It just started doing this, and the only changes made to the sled are that I put on a new belt.--The speedo did work correctly for 3.1 miles after the new belt. I really don't want to take the sled to the dealer, because the days left to ride around here are dwindeling. Any help would be great. Thanks alot!
