When you programmed the new tach speedo did you program the tank size. If not then you did not do it right. Ask me how I know. Once I figured that out my range shows up. Its gets a bit more accurate with more fillups. The problem with getting the Range, etc all to work is having that jumper correct under the seat. I put it wrong the first time so I took it off and rode a couple weeks without it. Then I finally got a bit of help in doing it right and ordered a new adapter plug and everything went smooth.
