Wow, nice bike! Most of the leaks I see on these bikes are transmission leaks through the main shaft. My solution has been a product called the "super nut" and the liberal aplication of Permetex's "the Right Stuff", (best sealer on the planet), to the splines on the drive sprocket and the output hub. This is the only way I've found to seal the chronic leaks on Harley 4 speed transmissions. And, boy does it work well.
