| This is a fix for the famous clutch shell wobble breaking magnets & stator issues on the late 84-85 ironhead and 86-90 evo engines without going to aftermarket products. The V-twin clutch and the zippers trapdoor are nice parts but I don´t think that is where the problem started. The wobble on the clutch gear splines is what I think is the biggest problem to fix in most cases. If the clutch shell can´t wobble, the magnets will not hit the stator and the problem is fixed. \\ | This is a fix for the famous clutch shell wobble breaking magnets & stator issues on the late 84-85 ironhead and 86-90 evo engines without going to aftermarket products.

If your splines are good, you can still made that improvement and it will probably help to keep the splines good.
