DIODE BOARD This is a totally redesigned diode board for all aircooled Boxer twins with alternators. It is designed with reliability in mind and costs less than the original part. [$75].

SOLID BOARD MOUNTS These solid mounts replace the breakage prone rubber board mounts.Order these with a diode board and save $$.[$15/$18]

VOLTAGE REGULATORS Two types are available: one is a high output replacement for the factory supplied part, the other is adjustable so you may fine tune it to your requirements. Both cost less than the factory replacement. [$23/$28]

IGNITION MODULES This is a direct replacement for the electronic ignition module used in all Boxers equipped with electronic ignition at considerably less cost. We sell two units - the earlier unit that bolts onto a heatsink and the later unit that comes with heatsink installed. Click here for more information[$55]
