The stock Road Star ignition module does an adequate job of controlling the sparkplug timing and RPM limitations, as long as you're running a reasonably stock engine, stock carburetor--and you don't mind being limited to 4,250 rpm for 1600 series engines, or 4,750 rpm for 1700 series engines. But if you want to install an aftermarket carb, increase the rev limit, add high compression pistons, or go big-bore, you'll need to replace that little black box with a Dyna 3000 or SpeedStar, direct replacement, ignition module.

Parts List:

• Dyna 3000 or SpeedStar ignition module

If you intend to cut an access hole in the battery box for the Dyna 3000 dip-switches, the following optional parts are for making a protective insert for the dip-switches:

• Small foam brush
• Plastic shopping bag

Tools:

• 5mm hex (Allen) wrench, for removing the bike's side-cover
• Metric socket wrench set (nothing fancy)
• Large Phillips (X) screwdriver or small socket wrench, to remove the battery terminals
• Slotted (--) screwdriver and needle-nose pliers, to reinstall the battery's rubber retaining straps

If you intend to cut an access hole in the battery box for the Dyna 3000 dip-switches, the following tools will be needed:

• Electric drill, Dremel or similar tool
