I have a 120" build with 4 1/8" bore and 4 1/2" stroke that doesn't have that rattle and the skirts are shorter than those on the 110". Just saying that the 110" doesn't have to slap because of skirt length.
Ab-so-lutely!!! The entire skirt length issue is just one more of the many bogus answers floated by H-D and their minions when they either don't know the real answer, or don't want to spend the money to fix the real problem. Don't forget, until recently the official word from the MoCo was "problem, we don't know about no steenkin' problem" when queried about things like oil leaks on the 110.
Anybody pulled their pushrods after plenty of miles and looked closely at them for contact on the sides? Just wondering after reading the blurb in the catalog for the new tapered SE pushrods if perhaps the MoCo already knows the cause but as in the case of the compensator instead of correcting the problem in production they just came up with another way for the customer to pay for his own fix.

" SCREAMIN’ EAGLE® PREMIUM TAPERED
QUICK-INSTALL ADJUSTABLE PUSHRODS
These premium pushrods are
tapered for enhanced clearance
at the cylinder head, allowing the use of higher lift
cams. "
