That sounds like a tough one Albie. As far as I can remember the monster speedo's like most in the range are sealed at manufacture, ask anyone who has tried to fit an MPH sticker over a KPH speedo.
However - I do believe they can be opened up by cutting the top off then glueing it back on again. No doubt someone will be along in a moment to tell you how to do this properly.
