This is a fairly common symptom, caused by wear in the bearing on which the
internal spinner turns within the drag cup. When the bearing is worn out
and begins to wobble at high speed, it allows actual glancing contact to the
drag cup, which will peg the needle. You need a replacement speedometer,
Kerry, or else take it to a speedometer repair place and have them go
through it.
Sometimes lubrication of this bearing will settle things down for a little
while, but the problem will recur, especially in cold weather. You could
try some oil in the wick above the cable socket - it might help for a while.
Also make sure the cable is not bent and applying sideways pressure on the
back of the speedometer head - this makes the problem worse by stressing the
bearing. I've seen them where simply re-routing the cable to avoid any
sideways pressure or twist on the cable will calm down a noisy or erratic
speedometer - again, for a little while anyway.

My 'new' 62 has an interesting speedo problem. When you get up to about 65,
the traveling band (needle) goes up to about 100 pretty rapidly and stays
there until you slow down below 40 or so.
Anyone seen a problem like this?
