The 6v starter will work just fine, a 12v much better, but you will need a 12v solenoid, or a voltage drop for a 6v solenoid after you convert to 12v. COE and automobiles used remote starters w/solenoids.

Are you planning on key start switch or a push bottom mounted on the dash?

As stated above to use a 12v starter you have to change the ring gear on the flywheel. I believe a 6v ring gear is 139 teeth and 12v ring gear is 168 teeth.

And if memory serves me correctly a 6v starter has a 10 teeth on the drive gear and a 12v has nine teeth.
