The Acewell is indeed ace. It's connected into the speedo drive output on the gearbox using a cable from
Boxxerparts (great shop).
One problem - the side panels are fiberglass copies. The man who did the painting said that it's difficult for them to get a perfect and lasting finish on fiberglass surfaces. The material also dents very easily.
