PMK:
My speedo is fine up to 60 then it seems to lag behind a bit. At 75 on the GPS it's actually reading 70 and reads 75 at 6,000 rpm.

Sometimes as I go over a bump at that speed the needle drops and rises.

Should I be looking at the clock or the drive?

Spitfire:
The speedo on my F1 is 7 mph fast at all speeds, I clocked it against the car, as to strange readings I would check the cable, oil it or change it.

Seamus:
May also be worth checking the route of the cable. Try the inexpensive methods first  :D

BigAl (Alan):
My speedo is 5-7 mph too fast, but I always thought it was a feature with Japanese bikes?

Even my R1 reads fast...I checked it against my GPS.

I think that all vehicles over read, but it's good to know by how much. More modern vehicles can have a 'speedo healer', but only for electronic ones.

On my Exup it has a mechanical drive...it is 20 years old this year...& I had the same problem with an erratic reading. I Removed the drive cable, cleaned & lubed it, & now it reads a more stable reading.
