I have just recently picked up a 1990 imported\nKawasaki zzr. The Speedo is in kph. In the lower\ncentre of rev counter there is a four digit counter\nthat only advances when the bike is moving. The\nthing is though, it only advances ever 3/4 of a\nkilometre and I can not work out what it is for. It\nwill not reset and only goes up to 9999.\nany ideas as to what it is for.\n\ntaz.
