They make a second coil kit that about doubles the amp output. It has a simple to install voltage regulator. The stock 420 uses 1 coil. It puts out around 3 amps. If you retain the stock flywheel you can add a coil and regulator.do you guys know anything about installing a voltage regulator into a 12v dc system on a go kart with a 12v battery etc. for front light etc.
ive looked at a few of them and the 4 wire harness/pigtail wiring seems to be pretty common but still want MORE input from people who can advise how this setup works?
thanks mike.
