This is a brand new aftermarket generator stator for the big twin Kawasaki Vulcan range, covering the Vulcan 1500 and 1600 in Drifter, Nomad, Classic and Mean Streak form. It is a direct replacement for the original unit, supplied with the connector and rubber grommet already fitted, so it installs in the engine case exactly where the original sat and plugs into the existing harness with no rewiring and no splicing.
These heavyweight cruisers ask a great deal of the charging system - long touring miles, heated grips, driving lights and audio all draw from the same output - and the original stators are known to cook their windings over time. RMSTATOR wind this replacement with the highest grade copper, rated to 200 degrees Celsius, over the highest grade laminations. The opposite connector for the main harness side is supplied too, because a melted or corroded harness plug is one of the most common reasons a newly fitted stator fails again. Every unit is tested before it ships.

Frequently Asked Questions
Will this stator fit without modifying my bike?
Yes. It is a direct, plug-and-play replacement for the original generator stator. The outer and inner diameters, the thickness, the three wire layout and the plug all match the factory part, so nothing needs cutting or adapting.
What is included in the box?
The generator stator with its connector already fitted, the rubber grommet, and in addition the opposite connector for the main harness side.
How do I know my old stator has failed?
A failing stator on these Vulcans shows up as a battery that will not hold charge, charging voltage that does not climb as the engine revs, and in bad cases a burnt smell from the engine. With a multimeter, each pair of black wires should read roughly 0.7 ohms and none of them should show continuity to earth.
Should I replace the regulator rectifier at the same time?
It is worth testing it. A regulator rectifier that has failed short can destroy a new stator, so if the original stator burnt out rather than simply going open circuit, check the regulator rectifier before fitting the replacement.
