I've been thinking of adding a few guages to my scoot. Listed in order of priority are tachometer, voltmeter and cylinder head temp. The voltmeter and cyl head temp sender are going to be a cinch...but the tach looks like its not going to work. I've looked at both for VDO or Autometer tach's but the sender are all listed for 4,6 or 8cyl engines. Has anyone found a sender for a VDO/Autometer that works for a 4 stroke single? The only ones I've found so far are these digital tachs....looking for a dial...any suggestions?
