Is there such? I want to have my m/c battery charge a little higher, so that it powers the MSD box properly.

[Voltage regulators for generators are adjustable >I have never had the cover of one for and alternator My 1922 Model T speedster has a 3 brush generator and a cut out relay. It is adjustable by moving the 3 rd brush location in the generator. another option might be changin your pullies. In the 50's A high reving engine could explode the generator windings.

PREMIUM ADJUSTABLE EXTERNAL VOLTAGE REGULATOR CHRYSLER DODGE PLYMOUTH, 1970-87 | eBay a quick google search shows one

GM mechanical voltage regulators from the 1960s were adjustable.

From MSD "The Ignition will deliver full voltage with a supply of 9 - 18 volts."
Anyway, depending on your regulator if its ground is through a wire and not from being bolted on, you can add a low ohm resistor in the ground line. It would be hit and miss but I'd start at about 3.3 ohms, 1/2 watt or maybe 1 watt would be enough. The higher the resistance, the higher the output voltage. That is the ground wire from the actual regulator to ground. Not the alternator ground.

Turns out that I don't need the regulator. I didn't ground the HEI module. Once I did, the bike turned on like it should.

Oh a bike! I was thinking you had a race car that only had a m/c battery to run and an external one to start for weight savings.

Lol. Sorry for not being clear.
