I go to ride my "new" 02 Viper that I bought this year. Put about 25 miles on her mainly to ferret out any running problems. The only problem I came up with is the speedo. The numbers bounce all over the place - 15-35-17-20-42-ect. Just want to know if anyone else has had this problem and if so is it the pickup on the driveshaft or the speedo itself?
