I'm pretty sure all H.D. engines are dry sump engines, forced lubrication supplied by pump from an external tank.
+++++++++++++++++++++++++++ Thanks Pete I really wish this is true, but I am struggling to see it. Where does the lube go - the pump has to scavenge from somewhere? I saw potential in two engines Hz opposed (laying on their side) driving a common shaft through one-way needle roller clutches. Therefore twin engine reliability in a single engine and the weight was about right. I dropped the idea coz I thought the motors would have to be vertical and upright in tandem. The current breed of Harley motors come equipped with EFI and put out impressive numbers without being forced - a re-drive improves things and could be incorporated in the common drive shaft. What is a shovel? Take care Steve J
