Another warning with the sump plug, if you do remove the plug make sure it is fully home and tight when refitting if not the vibration will cause it to come out. I discovered this with catastrophic results requiring a new engine.
Yes, the temptation is always to lean on the sump plug due to fear of the consequences of it coming undone. However, it's equally important not to do it up TOO TIGHT as I found out to my cost recently when I discovered that my sump plug threads had stripped. 1/2in Helicoil kit on order! Interestingly I cannot find any recommended torque setting for the X-Wedge drain plug in the S&S documentation. Harley seem to specify 14-21 ft-lb and I'll certainly be using a torque wrench in future. I'm normally pretty careful with this kind of thing so I reckon that if it can happen to me it can happen to anyone!
