Spedometer problem My scooters speedometer is off. the faster I go the more off it is. Anyone know how to adjust it?

Actually as the tires wear the error increases. If you have a mechanical speedometer and you're fairly mechanically minded you can take the speedo apart pull the retaining pin on the watch spring, increase the tension a bit and put it back together. I've done that before. Not sure how your instruments are made, but you don't want to destroy things doing so. The other option is to get some stick on numbers and stick them on the bezel at their appropriate positions. For example, stick 45 over the 55 speedo number. Check at sign makers to see if them can fix you up with numbers. Any more they have machines that laser cut adhesive vinyl and can make any desig you want. ,,,
