hey guys, i just took my bike to destin florida. it was 266 miles from my house. i had a problem after i filled up my gas tank at a shell station. when i was on the interstate, the speed on the speedo kept jumping around. i was cruising at about 70mph, but my speedo kept jumping to 97, 86, 35, etc..... i just installed a power commander on my bike, so i didn't know if that could have been the problem or not. anyone else had the speedo problem or any solutions to fixing it??? it only happened once in a while during the whole trip. other times the speedo was reading correctly. thanks for any help.
