Thanks for all the input,
The reason I am going to wait till fall is I am allready riding the bike with a bad stator. I am planning on pulling the engine this fall to replace it, and I will do the spline lube then. I don't ride it far, nor often, and it's 32 years old, a couple of more months shouldn't matter. Thanks
Kawasaki introduced the 750 cc class Vulcan worldwide in 1985. Due to tariff restrictions in the United States on bikes over 700 cc imported from Japan, the initial US spec model was limited to 699 cc. The tariff was lifted in 1986 and the Vulcan went to 749cc.
