VAPE CHARGING & IGNITION SYSTEM FOR YAMAHA 1970-78 DS6/7, R5, RD250, RD350, RD400C (SHORT SHAFT)

About the Vape Ignition system:

Upgrade your tired old electrical system with a powerful modern 12 Volt all-in-one solution. No more timing adjustments; this system is set-and-forget. You'll have brighter lights, fat CDI sparks resulting in fewer fouled plugs, and no more getting stranded from a weak battery. You could even run with no battery at all. 

The Vape charging system comprises a 12 Volt 180 Watt single-phase permanent magnet alternator (PMA) and a exclusive regulator/rectifier compatible with lithium-ion, AGM, and lead-acid batteries. This system provides a considerable voltage increase at low RPMs, meaning you're reaching charge voltages sooner and not just relying on your battery voltage in stop-and-go traffic. The ignition system produces its own power, so the stator only needs to maintain voltage for the starter and lighting. 

Vape ignition systems use capacitive discharge (CDI) tech to produce fat, blue ignition sparks that improve fuel combustion and inhibit plug fouling regardless of available battery voltage. The system includes coils, wires, caps, and an ignition signal pick up. 

Vape RD kits do not come with a woodruff key slot. We hear concerns about this from time to time. We use these on our own projects and in all the years we've sold these, we've never seen a single issue. Many bikes don't use keys, and a correctly installed rotor doesn't need one. Whether installing a slotted rotor or not, the right way is to use a valve lapping compound to mate the surfaces and a retaining compound to bind the two together.
