if its electrical, not much else.
if its gear driven like older patrols $20-35 gets you a plastic gear you can change.

Run along with a GPS, mark on the speedo correct speeds.

Where can you get these plastic gears from Bruce, me getting 35's and would probably rather change the gear as its not that hard.

[quTry this
GQ SPEEDO DRIVE GEARS . The following has worked for me in a few combinations. They are pretty close approximations in others .
It also shows by looking at gear No (ie 17) how close ratios and tyre sizes are to normal.
Normally 2350 is 100kph ie. About 43kph/1000rpms in 5th.
You can check your speedo on the highway using K markers. At 100kph it takes 36 seconds. For 5 ks its 180secs or 3mins.
