What size are your wheels. The speedometer wants 26" or 27" wheels. Yours must be smaller.
 
those things are consistently 30% high. nothing to do about it but print a new faceplate for it
 
my 1960's speedwell one works ok on 20" wheels...

theyre all wheel diameter dependent. a 27" will just get faster and fasteer with smaller wheels...a 20" model will just get slower and slower with larger wheels...

reprinting the face plate is a good idea though ;) even laminate the little cutout so its weatherproof...
 
Tried the same one with mine on these... almost 20 mph over, tried a 26" on the front and got about 10 over estimated. I doubt these we're intentionally supposed to be accurate. I do however like the idea of the fix you guys mentioned about replacing the measurements with another print out. I'm waiting on a mag, replaced the factory cdi and mag but, the mag got moister due to the well hidden pinched gasket i had issues with. I'm Looking Forward to next week though. Should have it all back and ready to hit the road. I switched frames because this frame warped due to it being aluminum. I did put in a set of rear brakes after these pictures we're taken.
