Thanks Chris.
There are a couplke of things I would consider doing.
The first is to replace the speedometer motor with the one from a cheap rev counter I would buy on Ebay.
Or, I will consider creating a new dial for the speedometer, using a colour printer or something. the new scale will stop where the 160mph value now is, but the new value at that position can be anything, for example 220mph.
you will have some free space on the speedometer dial which you can use to add a couple of leds, when the led controller "Pro Shift" is out.
Cheers
