Hi Barry - your crankshaft does indeed have the restrictor orifice jets in it. In fact, I can even remember that your crankshaft rod and main diameters were turned to 1.240. The biggest problem that I have run into is that the windage tray needs to have two large holes drilled in between the numbers 1 and 2 rods and 3 and 4 rods. This allows oil to get back to the sump faster and potentially avoid the flywheel phenomenon you posted about. I have seen the flywheel scraper cast into the KJ oil pan as described in your post a la V-twin. What is more alarming with Hendersons is, in preparations for Cannonball, Crawford and Bramwell were given the task of relocating the oil pickup from the rear of the Henderson oil pan to the center. The stock pickup will only deal with an 11 degree angle to the front before pickup starvation occurs. We are talking the Rockies. Moving the pickup to the center, and we are still testing as to where its final spot will be, has gained us a 22 degree angle before starvation will occur. I cant see how the big pump could hurt a deluxe, as in previous posts, cycling oil is the number one weapon to removing heat. We have had good luck with the windage modification, however there will very soon be a pack of Hendersons dealing with riding conditions that will put the system to the test in a very public setting. This is a greeat thread and time appropriate. Mark
